Stainless Steel 310 Stud Bolts, also known as UNS S31000 or by its European equivalent 1.4845, is a high-temperature austenitic stainless steel alloy. Stainless Steel 310 stud bolts are specialized fasteners made from this alloy, offering unique properties that make them suitable for high-temperature and corrosion-resistant applications.
Key Features of Stainless Steel 310 Stud Bolts (1.4845):
High Temperature Resistance: Stainless Steel 310 is renowned for its exceptional resistance to high temperatures. It can maintain its mechanical properties even at temperatures well above 1000°C (1832°F). This property makes it ideal for applications involving extreme heat, such as in furnaces, heat treatment equipment, and exhaust systems.
Corrosion Resistance: While not as corrosion-resistant as some other stainless steels, 310 offers good resistance to oxidation and corrosion in mildly corrosive environments. This makes it suitable for applications where exposure to heat and some level of corrosion is expected.
High Strength: Stainless Steel 310 stud bolts maintain good tensile and yield strength at elevated temperatures, making them reliable for holding together components under thermal stress.
Scale Resistance: The alloy forms a protective, adherent oxide scale when exposed to high temperatures, which helps protect it from further oxidation and scaling.
