Inconel Refractory Anchors Manufacturer

Inconel refractory anchors are nickel-alloy refractory anchors — welded to a furnace, reformer or incinerator shell — that mechanically hold refractory lining in place at the highest temperatures. Made from Inconel 600, Inconel 601, Inconel 625 or Incoloy 800, they withstand extreme heat, oxidation, carburisation and thermal cycling where stainless steel grades reach their limit, and are usually custom-made to customer drawings.

Use Inconel anchors when the service temperature or atmosphere exceeds what stainless can handle — typically above roughly 1100 °C, or in reducing, cyclic, carburising or sulphidising atmospheres. Stainless grades such as SS310 and SS330 cover service up to about 1100–1150 °C; beyond that, or where the atmosphere is aggressive, Inconel 600/601 and Incoloy 800 are specified.

Inconel 600 is used to about 1175 °C and Inconel 601 to about 1200 °C, with outstanding oxidation resistance from its aluminium addition. Incoloy 800/800H/800HT serves to roughly 1100–1150 °C with excellent creep strength. The exact limit depends on the atmosphere, loading and cycling, so confirm against your service conditions.

Both are nickel-chromium alloys, but Inconel 601 has an aluminium addition that gives it superior high-temperature oxidation resistance and a slightly higher service ceiling (~1200 °C), making it the top choice for severe oxidising and cyclic service. Inconel 600 (~1175 °C) excels in reducing and cyclic atmospheres and resists chloride stress-corrosion cracking. We supply both to drawing.

Inconel 625 is used where high strength and outstanding corrosion resistance are needed together — in hot, corrosive or sour atmospheres and where the anchor carries significant load. It combines excellent oxidation resistance with very high strength and is specified where 600/601 alone would not meet the mechanical or corrosion demands.

Incoloy 800, 800H and 800HT are iron-nickel-chromium alloys used for high-temperature anchors with excellent resistance to oxidation, carburisation and creep — 800H/800HT have controlled carbon and grain size for superior creep-rupture strength, making them common in reformer and pyrolysis furnace service to about 1100–1150 °C.

Yes — this is our specialty. We manufacture Inconel refractory anchors exactly to customer drawings, samples, sketches and technical specifications, including custom dimensions, wire diameters, flat-bar sizes, bending profiles, welding details and grade. Most refractory anchors used on real projects are custom-made, and we are set up specifically to produce non-standard anchors in nickel alloys to spec.

Yes. Custom manufacturing is the core of our business. Send a drawing, sketch or sample and we will produce the Inconel anchor to match — in prototype quantities for trials or full production quantities for projects, in the grade and form your lining and temperature require.

Yes. We routinely reverse-engineer refractory anchors from a physical sample — measuring the geometry, wire/bar size and material — and reproduce it accurately in the specified Inconel or Incoloy grade, ideal when the original drawing is unavailable or you need a like-for-like replacement.

Ideally a drawing or sketch (or sample), the anchor type, Inconel/Incoloy grade, wire diameter or flat-bar size, key dimensions, quantity and your delivery location. If you are unsure, send your lining type, thickness, operating temperature and atmosphere and our team will recommend a suitable anchor and grade and quote.

Yes. Non-standard and project-specific anchors are exactly what we make. Most refractory anchors used in industrial projects are custom-made, and we specialize in manufacturing non-standard Inconel anchors to customer specifications — special shapes, sizes, grades and welding requirements included.

Both. We make small prototype quantities of Inconel anchors for trials and qualification, and large production quantities for full projects and turnarounds. Order quantities are flexible to suit your project stage.

Inconel 600 (UNS N06600), Inconel 601 (N06601) and Inconel 625 (N06625), plus Incoloy 800 / 800H / 800HT (N08800/N08810/N08811) and RA330 (N08330). Other heat-resistant nickel alloys are available on request. The grade is chosen to match the maximum service temperature, the atmosphere and the mechanical loading.

Inconel's high nickel and chromium content gives it exceptional resistance to oxidation, scaling, carburisation and the fatigue of severe thermal cycling at temperatures where stainless steels weaken or scale. That means the anchor keeps its strength and stays sound for the life of the lining in the hottest furnaces, reformers and incinerators.

Yes. Inconel 600/601 and especially Incoloy 800H/HT offer strong resistance to carburisation in reducing and carbon-rich atmospheres, and Inconel 600 resists many sulphur-bearing and chloride environments. The right grade is selected for the specific atmosphere — reducing, oxidising, carburising or sulphidising.

A V type Inconel anchor is a V-shaped wire anchor welded to the shell by its legs — the most common, economical anchor for monolithic refractory, made in Inconel 600/601 for high-temperature furnaces, heaters and ducts where stainless would not survive.

A Y type Inconel anchor has a single stem that splits into two legs forming a Y, welded by the stem so it anchors deeper into the lining — used in Inconel 600/601 or Incoloy 800 for medium-to-thick monolithic refractory in petrochemical reformers, heaters and reactors.

A Flat Type Y Inconel anchor is a Y-shaped anchor made from flat bar rather than round wire, suited to thicker linings with improved load distribution and holding power — widely used in Inconel 601 and Incoloy 800 in petrochemical heaters, reformers, furnaces and boilers.

Both are Y-shaped, but a standard Y anchor is made from round wire while a Flat Type Y is made from flat bar. The flat bar spreads load over a larger surface, so the Flat Type Y holds thicker, heavier linings better — preferred on demanding high-temperature petrochemical linings in Inconel and Incoloy grades.

A bull horn Inconel anchor has two curved legs that splay outward like horns, giving high pull-out resistance in thick, heavy castable linings at high temperature — a strong choice in Inconel 601 for demanding reformer and furnace linings.

An H type Inconel anchor is a high-holding-power anchor (often corrugated) in a double-V / H form for thick, heavy monolithic linings needing maximum retention at high temperature, made in Inconel 601 or Incoloy 800.

A UV type Inconel anchor combines U and V geometry for additional anchoring points, suiting heavier or thicker high-temperature linings that need more grip than a single V provides.

A crook anchor is a simple single-leg anchor bent into a crook/hook, welded to the shell, used for thinner refractory and ceramic-fiber linings — supplied in Inconel where the hot-face temperature requires it.

An L type Inconel anchor is an L-shaped (right-angle) anchor or stud used to retain refractory tiles, bricks and lining edges, and as a base for brick-holding systems, in high-temperature nickel-alloy grades.

A slitted anchor is a flat metal strip with slits that key mechanically into monolithic or ceramic-fiber refractory, giving good grip from a low-profile weldable base — made in Inconel for high-temperature service.

A refractory brick holder (brick anchor/clip) mechanically retains refractory bricks or tiles against the shell — used where the lining is brick rather than castable, in Inconel/nickel-alloy grades for the highest-temperature brick linings.

A twist-lock anchor is a stud-welded serrated anchor for ceramic-fiber blanket: the blanket is impaled over the stud and a twist-lock washer is twisted onto the serrations to lock it. In Inconel 600/601 it is used for the hottest fiber-lined furnaces. See our Insultwist twist-lock studs.

A twist-lock washer (fibrelok / pressed lock washer) is a pressed metal washer with a central slot that pushes over the serrated section of a twist-lock anchor and twists a quarter-turn to lock the ceramic-fiber blanket at the hot face — supplied in Inconel for high-temperature service.

A speed clip washer is a pressed clip that pushes onto an anchor's serrations (or round rod) to quickly retain intermediate layers of ceramic-fiber blanket during installation, before the final lock washer is fitted.

A stud anchor (weld stud / pin) is a straight or headed pin welded to the shell to anchor ceramic-fiber or monolithic refractory — used in large numbers across fiber-lined surfaces, in Inconel where the temperature requires a nickel alloy.

A christmas-tree anchor has multiple branching legs along a central stem, giving many grip points and very high holding power in thick, heavy monolithic linings — supplied in Inconel 601 / Incoloy 800 for maximum retention in the hottest service.

Refineries and petrochemical plants (reformers, cracking and process heaters), fertilizer and chemical plants, sulphur recovery units, waste incinerators, steel reheating and heat-treatment furnaces, and power plants — anywhere the hot-face temperature or atmosphere is too severe for stainless anchors.

Yes. Inconel anchors are supplied with EN 10204 3.1 mill test certificates confirming the grade and chemistry, with full raw-material verification and batch traceability.

Yes. Positive Material Identification (PMI) by XRF or optical emission is available on request to confirm the nickel-alloy chemistry of the finished anchors — important for Inconel/Incoloy grades — with the PMI report included in the documentation.

Raw-material verification, PMI testing, dimensional inspection against the drawing, visual inspection of forming and welds, and a final inspection report — with batch traceability throughout. Tesco Steel & Engineering is an ISO 9001:2015 certified manufacturer.

Yes — nickel alloys cost more than stainless steel, so Inconel and Incoloy anchors are specified where the temperature or atmosphere genuinely requires them. Where service is within the stainless range, SS310 or SS330 stainless anchors are the economical choice; for the most severe duty, the longer life of Inconel justifies the cost.

Lead time depends on type, grade, quantity and material availability — prototypes are fast, and production quantities are scheduled to your project. Send your drawing and quantity and we will confirm a delivery date with the quote.

Yes. We are a manufacturer and exporter and ship Inconel and nickel-alloy refractory anchors worldwide with appropriate export and custom packaging, with export experience across the Middle East, Europe, Asia, Africa and the Americas.
