Jiangsu bealloy co.,ltd Providing a wide-ranging collection of Alloy 20 Fasteners. ASTM SB 160 ALLOY 20 Fasteners (UNS N08020)is stabilized with columbium to minimize carbide precipitation during welding. Carpenter 20 Fasteners appears to fall between both the stainless and nickel categories as it contains characteristics of both. Also termed as UNS N08020 Fasteners, it was designed specifically to withstand sulfuric acid.

Our Alloy 20Cb3 Fasteners is a solution for stress corrosion cracking that can occur when stainless steel is introduced to chloride solutions. ASTM SB 160 ALLOY 20 CB-3 Fasteners particularly excels in resisting corrosion to hot sulfuric acids when compared to conventional stainless steels such as 316. also contains niobium for stabilization against sensitization and resultant intergranular corrosion. We as well offer these products in custom-made sizes and shapes to our clients.
