Harsh Metalloys is a trusted manufacturer and supplier of Stainless Steel 442 Stud Bolts in Mumbai, India, delivering high-performance fastening solutions for heat-resistant and corrosive industrial environments. Stainless Steel 442 is a high-chromium ferritic stainless steel known for its excellent oxidation resistance and strength at elevated temperatures. These stud bolts are ideal for applications requiring durable, corrosion-resistant fasteners in thermal and chemical processing systems. Harsh Metalloys offers SS 442 stud bolts in various sizes, thread types, and finishes, conforming to international standards. Precision-engineered and rigorously tested, our stud bolts ensure reliability and durability even in the most demanding service conditions.
Stainless Steel 442 Stud Bolts are composed primarily of chromium (18–23%) and iron, with minimal carbon content. This composition provides enhanced scaling resistance and strength at elevated temperatures, typically up to 1000°C. The alloy exhibits a tensile strength of around 450–550 MPa and good resistance to oxidation and thermal fatigue. Though non-hardenable by heat treatment, it offers excellent dimensional stability. Harsh Metalloys ensures that each stud bolt is manufactured to precision standards with accurate threading, corrosion resistance, and mechanical strength, making them suitable for thermal and structural fastening needs in challenging environments.
