Harsh Metalloys is a renowned manufacturer and supplier of Stainless Steel 330 Bolts based in Mumbai, India, delivering high-performance fastening solutions for extreme industrial conditions. Stainless Steel 330, also known as Alloy 330 or UNS N08330, is a heat-resistant austenitic alloy developed for high-temperature and corrosive applications. Our SS 330 bolts are available in various types including hex bolts, stud bolts, and custom fasteners conforming to ASTM, ASME, and DIN standards. These bolts offer excellent strength, oxidation resistance, and structural integrity at elevated temperatures, making them suitable for use in furnaces, thermal processing plants, and petrochemical industries.
Stainless Steel 330 Bolts are composed of approximately 35% nickel, 17–20% chromium, and small additions of silicon, manganese, and iron. This alloy exhibits high resistance to carburization, oxidation, and thermal shock. It delivers a tensile strength of about 600 MPa and a yield strength of 275 MPa, maintaining its mechanical stability even at temperatures exceeding 1150°C. With excellent creep strength and resistance to scaling, SS 330 bolts are ideal for continuous high-temperature service. Their non-magnetic nature and good weldability make them suitable for critical fastening applications in harsh thermal environments.
