Heat Resistant Steel AISI 446

Heat resistant steel AISI 446 AISI 446 equal material : SUH446,UNS S44600 ,X8Cr28, Material 1.4083  is heat-resistant steel, the Japanese JIS standard ferrite series heat resistant steel. Because of this kind of steel is ferrite, quenching can not get martensite organization. Because at about 600 degree slow
cooling, on the precipitation of alpha phase after annealing embrittlement, therefore, from the 780~ 880 degree air cooling is necessary because of the high temperature oxidation resistance, therefore, the heat resistant parts under 1100 degree (sheet) and anti sulfur gases, high corrosion resistance, used in the
heating box, nozzle, domestic oil heater's combustion chamber and other components.
