  • AISI 430 UNS S43000 Stainless Steel Round Bars

    AISI 430 UNS S43000 Stainless Steel Round Bars

    430 (1.4016, UNS S43000) stainless steel is called "stainless iron" in the industry because it is a kind of ferritic stainless steel, has good corrosion resistance, and has better thermal conductivity than austenitic stainless steel. 430 stainless steel is currently mainly used in room temperature or high temperature scenes such as building decoration, some home appliance parts, fuel burner parts, etc. However, because the chromium content in 430 stainless steel is much less than that of 304, it is not as good as 304 in terms of hardness.
