How high temperature can 446 stainless steel withstand?

The maximum operating temperature of 446 stainless steel can reach 1093℃, and it can reach 1200℃ for short-term use. ‌

446 stainless steel is a material with strong high-temperature corrosion resistance. It will not produce easily flaking oxide scale below 1082℃, which makes it particularly suitable for high-temperature environments such as combustion chambers. In addition, 446 stainless steel has the characteristics of high corrosion resistance, weather resistance and high strength. Although it will become brittle in the temperature range of 700-1000°F, and will show sigma phase embrittlement at a long-term use temperature of 1000-1300°F, this does not hinder its application under specific conditions. The chemical composition of 446 stainless steel includes carbon (C), chromium (Cr), phosphorus (P), sulfur (S), molybdenum (Mo) and nitrogen (N). The content of these elements ensures its unique physical and chemical properties. Its heat resistance makes 446 stainless steel an ideal material for industrial furnaces and heating furnaces, and it can be used stably and for a long time in high-temperature environments. In addition, 446 stainless steel also has good oxidation resistance and sulfurization resistance, and is suitable for applications such as thermocouple protection tubes for heat exchangers and temperature control instruments.
