These Stainless Steel 442 Stud Bolts are primarily made of iron, chromium (18–23%), along with small amounts of molybdenum and silicon. This ferritic stainless steel grade boasts impressive resistance to scaling and oxidation, especially at high temperatures. In terms of mechanical properties, they have a tensile strength of about 550 MPa and a yield strength of around 275 MPa. SS 442 also shows good ductility and moderate resistance to corrosion. While it can’t be hardened through heat treatment, its structural stability and ability to withstand thermal fatigue make it ideal for high-temperature applications. Its well-balanced composition ensures both strength and performance in environments that range from moderate to aggressive.
