Casting / Heat-Resistant Castings

Heat-Resistant Castings

Heat-resistant castings retain strength, creep resistance and oxidation resistance at temperatures where carbon and stainless steels fail. Monmet supplies heat-resistant steel and Ni-Cr alloy grades to the specification on your drawing or purchase order.

Grade Selection

Heat-resistant Cr-Ni steel and Ni-Cr alloy grades are selected and microalloyed as needed for petrochemical reformer and pyrolysis tube service, to the specification on your drawing or purchase order.

Typical Applications

Ethylene cracker coils, steam reformer tubes, radiant tubes, walking-beam furnace hardware, kiln components and heat-treatment fixtures.

Centrifugal Casting Advantage

Most reformer and cracker tubes are centrifugally cast for maximum density and creep life. Monmet supplies finished tubes ready for welding into manifolds.

Frequently Asked Questions

Maximum tube metal temperature depends on the alloy grade, internal pressure and required design life — Monmet works with you to select and specify the grade for your service conditions.

Yes, with matching consumables and qualified procedures — though most operators replace rather than repair tubes after creep exposure.

Related Casting Capabilities

Centrifugal Casting

Vertical and horizontal centrifugal casting to drawing — most often bronze and other non-ferrous alloys, plus high-alloy stainless and exotic ferrous grades.

Stainless Steel Casting

Corrosion-resistant stainless steel castings supplied to the grade and test requirements on your drawing. Sand, investment and centrifugal processes for marine, chemical and food industries.

Alloy Steel Casting

Low and high-alloy steel castings: Cr-Mo, Ni-Cr-Mo and other alloy grades. Quench-and-tempered for mining, cement and heavy industrial wear.

Investment Casting

Precision investment casting (lost-wax) in stainless, tool steel, nickel and cobalt alloys. Tight tolerances and excellent surface finish for complex geometries.
