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
Ferritic/Martensitic: 1Cr13, 2Cr13
Cr-Mo: 12Cr1MoV, T91, P22, P91
Super Heat-Resistant: Incoloy 800H/HT, Alloy 625 (see superalloys)

Frequently Asked Questions
Q1: What grade should I use for continuous service above 1000°C?
A:
For temperatures >1000°C, grades like 310S, 253MA or Incoloy 800H are preferred due to their excellent oxidation resistance and creep strength.
Q2: Can you provide 12Cr1MoV or P91 pipes for power plant use?
A:
Yes, we supply high-pressure alloy steel pipes for boiler and superheater systems, compliant with ASTM A335 or GB 5310.
Q3: Do you offer welding wire/filler for heat-resistant steel?
A:
Yes. Welding consumables (ER310, ER347, etc.) can be supplied upon request.
Q4: What’s the delivery time for heat-resistant alloy plates?
A:
Standard grades are in stock. For cut-to-size or rare alloys, 7–15 days is typical.
Q5: Are inspection certificates included?
A:
Yes. MTC (EN 10204 3.1 / 3.2), third-party SGS, TUV, or BV inspection available.
