SUS441
Martensite stainless steel SUS441
441Overview and features of SUS441:
SUS441 is a type of martensite stainless steel. It contains very low carbon and nitrogen. The content of titanium and niobium is conductive to improve its high temperature strength, corrosion resistance, weldability and workability.Chemical compositions of SUS441 (%):

Heat treatment of SUS441:
1. Annealing: Slow cooling at 800~900℃ or rapid cooling at 750℃.
2. Quenching (Solution): Oil cooling at 950~1000℃.
3. Tempering: Rapid cooling at 700~750℃.Applications of SUS441:
SUS441 is very suitable for the applications in automotive exhaust system, exhaust manifold, front pipe, converter, thermal switch, electronic component, heat appliance, gas stove on board, decoration materials and so on.Our stainless steels are 100% ultrasonic inspected with relatively high quality and competitive price.
