stud bolt B8M , Iran

The B8M stud bolt, manufactured according to ASTM A193 Grade B8M, is made from austenitic stainless steel Type 316 and offers excellent resistance to chloride and acidic corrosion. Its chemical composition includes 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. In the annealed condition, it provides a minimum tensile strength of 75 ksi 515 MPa and a minimum yield strength of 30 ksi 205 MPa. The maximum surface hardness is 223 Brinell, and in certain cases, it can be supplied in a strain-hardened condition. B8M stud bolts are typically produced in diameters ranging from 1/4 inch to 2.5 inches with Unified 2A thread class.

The operating temperature range of the B8M stud bolt is from minus 200 to plus 550 degrees Celsius, making it ideal for use in chemical, pharmaceutical, and marine industries. Due to its high molybdenum content, it provides better resistance to chloride-rich environments such as seawater compared to B8 grade. Common applications include heat exchangers, chemical reactors, and process piping systems. These fasteners usually require no additional surface coating due to their inherent corrosion resistance. Quality control includes tensile testing, hardness testing, chemical analysis, and, when necessary, non-destructive tests such as PT or UT. B8M stud bolts are a critical choice in engineering design due to their superior corrosion resistance and thermal stability.You can order and buy stud bolt B8M from Iran by contacting us through whatsaap and email.
