A stainless steel material includes 14.6 to 16.1 wt % of chromium (Cr), 5.4 to 6.2 wt % of nickel (Ni), 1.5 to 2.2 wt % of silicon (Si), 0.001 to 0.05 wt % of carbon (C), 0.3 to 0.8 wt % of manganese (Mn), 2.5 to 3.2 wt % of copper (Cu), 1.2 to 2.0 wt % of cobalt (Co), 0.2 to 0.3 wt % of niobium (Nb), and a remainder of iron (Fe) and impurities. This stainless steel material provides better fluidity during casting, which helps in the formation of thin castings. It also allows for a reduction in yield strength as needed, making shaping easier while maintaining high tensile strength and impact strength. Compared to traditional dual-phase stainless steel material, its fracture strength is significantly enhanced.
