Stainless Steel 446 Stud Bolts are crafted from a ferritic stainless steel alloy, primarily made up of iron with 23–27% chromium, along with small amounts of molybdenum, silicon, manganese, and carbon. This unique composition offers outstanding resistance to scaling, oxidation, and corrosion, even at elevated temperatures. On the mechanical side, Stainless Steel 446 boasts a tensile strength of about 485 MPa, a yield strength of around 275 MPa, and an elongation of approximately 20%. These characteristics guarantee good thermal stability and mechanical integrity under high heat, making them perfect for critical applications that involve repeated thermal cycling and exposure to corrosive environments.
