Martensite stainless steel SUS441
441

 

Overview 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.
