Technical feature

Stainless high-temperature resistant high-alloy steel. The base of the alloy is iron: its share is about 56%. /The composition is alloyed with chrome, nickel, manganese, silicon. It is used in the manufacture of bands, pipes, pipe fittings, gate valves and similar parts operating at t° up to 950 °C under moderate stress. Weldability without restriction.
