Weston Stainless in Midland, UK, is a well-known supplier of excellent stainless steel products offering durable and reliable solutions for industrial use. Some of their specialized products include Stainless Steel 330 Bolts, which are used for severe heat and oxidation resistance. These bolts are of Grade 330 and come in several shapes like hex bolts, U-bolts, anchor bolts, and stud bolts. Made of chromium and high-nickel stainless steel, they possess great resistance to carburization, thermal cycling, and oxidation. Their strength and high durability characteristics make them suitable for severe service in power generation, petrochemical, and heat treatment industries.
Stainless Steel 330 Bolts consist of Nickel (34-37%), Chromium (17-20%), Iron (balance), and controlled levels of Silicon, Carbon, and Manganese. This composition offers excellent thermal stability and resistance to oxidation and carburization up to 1150°C. The bolts have a tensile strength of about 600 MPa, yield strength of about 300 MPa, and elongation of about 30%, with exceptional mechanical properties. The density is 7.9 g/cm³, with exceptional thermal expansion characteristics, so they retain structural integrity despite harsh heat and corrosive conditions.
