Stainless steel grades table

Heat-resistant steel is resistant to factors such as hot gases, burning products, molten salts and metals at temperatures exceeding 550ºC. Depending on chemical composition, the following steels can be identified: ferritic steels, austenitic steels, nickel-based steels.

Heat-resistant steels are used for industrial furnace construction, heat-resistant components of steam boilers, components of plastics dryers, in chemical industry, in power plants, in rolling mills for pipes and mill guides.
