ASTM A193 B8M Bolts

Visonalloys produces and manufactures ASTM A193 b8m bolts at effective costs. We deliver these bolts at best and defect-less conditions within specified time or earlier. We offer custom-made specifications of shapes, sizes, and dimensions to meet all the needs of the customers.

ASTM  A193 b8m class 2 is a standard specification of SS 316 fasteners which are also available in wide-range of collectible forms such as bolts, screws, studs, threaded rods, washers, etc. ASTM  A193 b8m bolts are used across elevated temperature atmospheres and for specific purposes where the tensile strength is highly required. ASTM  A193 b8m bolts, by means of standard grade, are also used across pressure piping and pressure vessels including special purposes applications such as chemical industries, and oil and gas industries. Grade ASTM  A193 b8m can be stress hardened and carbide mixture treated stainless steel that requires 100 ksi tensile strength and 50 ksi yield strength that have the maximum hardness range of 35 HRC or 321 HBW. ASTM  A193 b8m specification covers all requirements of clients for the chemical composition, mechanical properties,  heat-treatment, and hardness in specified time to all our esteemed clients. The chemical combination of ASTM  A193 b8m bolt is comprises carbon less than 0.08%, manganese less than 2%, phosphorus less than 0.045%, silicon 1%, chromium up to 18%, nickel 10-24%, and 3% molybdenum.
