It is referred to an alloy steel that can remain its strength and resistance against oxidation, corrosion or creeping under high pressure and temperature. Generally elements added to are : Ni., Cr., Al., Si., W., V., Co.,…etc. Among them, Cr. is the primary element that can form an oxide file to resist against the erosive gas under high temperature.
They can be classified into 2 types by alloy added to:
(1) Cr. series Heat-resistant Stainless Steel
(2) Ni. Cr. series Heat-resistant Stainless Steel
They can be classified into 2 types by microstructure:
(1) Ferrite series heat-resistant Stainless Steel
(2) Austenite series heat-resistant Stainless Steel
Compressor turbine, annealing box, exhaust valve cleaning device, fastening parts, spring, film, rotor of gas turbine, bolts.
Besides, heat-resistant Stainless Steel is often applied to petroleum industry, heat-treatment furnace parts or aircraft and automobile parts.
Often applied to producing utensils used in food, medical industries such as tableware, container, kitchenware and medical equipment.
