High chromium ferritic stainless steel, type SS 446, is typically utilised in high-temperature applications, with a temperature range of 1500 to 2200 degrees Fahrenheit. One of the high oxidation resistance steels in the 400-4xx range is this one. Additionally, compared to other alloying elements, it exhibits a superior resistance to cyclic oxidation. Furthermore, this substance is the heat-resistant alloy that can handle copper and brass that is molten. This material’s strength at high temperatures isn’t very good. Additional nitrogen alloy is added in order to refine the grain.
