Specialist in Manufacturing Industrial Steel Fasteners

ASTM A193 B8 Bolts

Vision alloy is one of the most astonishing manufacturers, suppliers, and stockists of stainless steel products. These products are highly efficient for industrial, commercial, and household uses. ASTM A193 B8 bolts are highly ductile and strong. We manufacture these bolts using high-quality metals and raw materials. These bolts are highly durable and highly tested. We at Vision Alloy manufacture and supply these products by taking all the safety precautions. 

These bolts are generally manufactured using stainless steel 304 grade. These bolts are manufactured using high-quality grade. This grade is highly malleable and ductile. These bolts are highly used for industrial purposes. The chemical composition of this grade includes a high amount of chromium, nickel, manganese, and other powerful elements. The combination of these elements provides excellent ductility and strength to the metal. ASTM A193 B8 bolts provide excellent resistance from corrosion, crevice corrosion, and stress cracking. These bolts are high resistible to erosion, reduction, and other chemical procedures. 

ASTM A193 B8 bolts are sturdy and ductile, it has excellent properties. Hence these bolts are applicable in industries like pharmaceutical, petrochemicals, acid-making industries, pulp and paper making industries, etc. The tensile and yield strength of these bolts is very high. The minimum tensile strength is 75 ksi and the the minimum yield strength is 30 ksi.
