Heat Resistant Stainless Steel

Heat-resistant alloys are those capable of being used at temperatures above 1200ºF / 670ºC under load in particular gas environments and are indicated by acceptable levels of stress rupture and creep strengths that correspond to the required time of service.  Main groups of heat-resistant alloys are high chrome nickel austenitic alloys a.k.a. heat resistant stainless, nickel-based alloys, and cobalt chrome nickel-based alloys.  Specific performance data for the variety of heat-resistant grades (Larsen-Miller creep rupture curve, coefficient of thermal expansion, elevated temperature tensile strength, and others) are available on request.
