Heat-Resistant Steel – Engineered for Elevated Temperatures & Thermal Fatigue Resistance
We supply a wide range of heat-resistant stainless and alloy steels for high-temperature environments such as furnaces, boilers, and reactors. Grades include austenitic, ferritic, martensitic, and Cr-Mo steels.
What Is Heat-Resistant Steel?
Heat-resistant steel refers to alloys that maintain mechanical strength, oxidation resistance, and thermal stability at high temperatures (500–1200°C). These steels are commonly used in thermal power, petrochemical, kilns, and industrial heating equipment.
Core Features:
Excellent creep strength,Resistance to thermal fatigue & deformation,Oxidation & carburization resistance, Long service life in cyclic heating environments.
Common Grades:
Austenitic: 310S, 253MA, 304H, 347H,2535Nb,RA330,314,309Si2
Ferritic/Martensitic: 1Cr13, 2Cr13
Cr-Mo: 12Cr1MoV, T91, P22, P91
Super Heat-Resistant: Incoloy 800H/HT, Alloy 625 (see superalloys)

Performance Characteristics and Applications of High-Temperature Resistant Stainless Steel Products
1. Performance Characteristics
1.1 High-Temperature Stability
High-temperature resistant stainless steel maintains stable mechanical properties, including creep resistance and fatigue resistance, under high-temperature environments, ensuring no significant deformation or failure during long-term high-temperature operation.
1.2 Oxidation Resistance
It possesses excellent oxidation resistance, forming a dense oxide film on the surface, effectively preventing further oxygen corrosion of the internal materials, thereby extending its service life.
1.3 Corrosion Resistance
It exhibits excellent chemical corrosion resistance in high-temperature corrosive environments (such as acids, alkalis, or salt spray), making it suitable for various harsh working conditions.
1.4 Low Coefficient of Thermal Expansion
A low coefficient of thermal expansion means high dimensional stability under drastic temperature changes, reducing the risk of cracks or deformation caused by thermal stress.
1.5 Mechanical Strength
It maintains high strength and hardness at high temperatures, making it suitable for applications subject to heavy loads or dynamic stress.
2. Applications
2.1 Industrial Furnaces
Components used in the manufacture of industrial furnaces such as heat treatment furnaces and smelting furnaces, including heating elements, furnace tubes, and supports, as they can withstand extreme temperatures without degradation.
2.2 Automotive Manufacturing
