Stainless Steel A193 Grade B8M Hex Bolts are engineered to meet high-performance standards in both strength and corrosion resistance. These hex bolts are integral in various industrial applications, particularly where durability and reliability are paramount. Vision Alloys specialises in providing high-quality stainless steel A193 Grade B8M hex bolts conforming to ASTM A193 and ASME SA193 standards. Additionally, these bolts adhere to DIN 933 and DIN 931 specifications, ensuring they meet international quality and safety benchmarks.
The composition of our A193 Gr B8M hex bolt includes austenitic stainless steel, primarily consisting of chromium, nickel, and molybdenum. Typically, these bolts contain 18-20% chromium, 10-14% nickel, and 2-3% molybdenum, providing excellent corrosion resistance, particularly against chlorides and other harsh environments. The B8M designation indicates the use of molybdenum to enhance pitting resistance, making these bolts ideal for use in chemical processing, marine, and other environments where corrosion is a significant concern.
