Technical characteristics

Stainless steel 40KH9S2 belongs to the group of heat-resistant and heat-resistant high alloy steel martensitic class. The steel used for the manufacture of intake and exhaust valves of engines of automobile and tractor machinery heat-resistant fasteners, as well as in pipelines of heat-exchange and recovery units. Anticorrosive properties of the steel is stored at operation temperatures up to 800…850°C in air and in sulfur-containing environment. The specific name of the steel — silichrom — due to the high content of silicon and chromium.
