Overview
UNS S32750 is a stainless steel containing high chromium, high molybdenum, high nitrogen and low carbon for excellent corrosion resistance and high strength. It excels in highly chlorinated and acidic environments and is widely used in the chemical, oil and gas industries.
Heat treatment is the process of changing the organizational structure and properties of UNS S32750 through process treatments such as heating and cooling. Carbon is an important alloying element in UNS S32750 and has a great influence on the properties of UNS S32750.
