Heat-Resistant Castings
Keep your components performing in demanding, high-temperature environments with heat-resistant castings from EQI. We help you select the right material for your application, including heat-resistant stainless steels, nickel-based alloys, and cobalt-chromium-nickel alloys. For parts exposed to temperatures above 1,200°F, mechanical loads, and challenging gas environments, our technical expertise supports your performance requirements.
Why Choose Heat-Resistant Castings?
For High-Temps & Longer Service Life
Reduce maintenance demands with components built to withstand your operating conditions. EQI helps you select heat-resistant alloys that resist deformation, oxidation, and thermal fatigue—helping extend component life.
Strength Under Fire
Support demanding loads at elevated temperatures with alloys selected to resist deformation and maintain component strength.
Durability for Harsh Environments

Heat-Resistant Castings FAQs
What are heat-resistant castings?
Heat-resistant castings are metal components made from alloys selected to maintain strength and resist degradation at elevated temperatures. They are commonly used in industrial furnaces, ovens, and heat-treating equipment.
How do I choose the right alloy for my application?
Temperature is only part of the equation. EQI evaluates your component’s loads, operating atmosphere, heating and cooling cycles, and performance requirements to recommend a suitable material.
What materials does EQI offer?
Options include heat-resistant stainless steels, nickel-based alloys, and cobalt-chromium-nickel alloys. Each offers a different combination of high-temperature strength and resistance to environmental degradation.
How does EQI evaluate high-temperature performance?
We consider mechanical properties under your operating conditions, oxidation resistance, thermal expansion, and the material’s ability to resist sagging or breaking at elevated temperatures.
Why does the operating atmosphere matter?
Gases surrounding a component can affect how an alloy performs at high temperatures. Selecting a material suited to your furnace atmosphere helps limit oxidation and other forms of chemical degradation.
Can heat-resistant castings withstand repeated heating and cooling?
The right alloy can help resist thermal fatigue caused by repeated temperature changes. EQI considers your heating and cooling cycles when recommending materials for your components.
What components can EQI supply?
We supply trays, baskets, fixtures, furnace rolls, rails, walking beams, chain guides, nozzles, heater elements, and other components for industrial ovens and heat-treating furnaces.
What information should I provide when discussing my project?
Share your component drawings, operating temperatures, loads, furnace atmosphere, and heating and cooling cycles. Details about current wear, distortion, or failures can also help us recommend a material suited to your application.
