Harshita Stainless supplies high-performance Stainless Steel 442 Stud Bolts from its Delhi, India facility. SS 442 is a ferritic stainless steel alloy with superior oxidation and heat resistance properties that make it suitable for high-temperature fastening applications. These stud bolts are engineered to be dimensionally accurate and thread consistently, made to high standards. They are offered in a variety of lengths and diameters and are compliant with ASTM and ASME standards. Harshita Stainless provides SS 442 stud bolts with good mechanical strength and resistance to corrosion for industries such as petrochemicals, furnaces, and thermal power plants in India.
SS 442 is comprised of 18–23% chromium and is low in nickel, enhancing its heat resistance and oxidation stability. It has good mechanical strength with tensile properties up to 620 MPa and high creep resistance at elevated temperatures. While not as ductile as austenitic grades, SS 442 has stable performance under thermal cycling. It is also ferromagnetic and retains surface integrity in oxidizing conditions.
