Astm A193 Grade B8t Bolts

ASTM A193 Grade B8t Bolts, ASTM A193 Gr. B8T Fasteners, ASTM A193 Stud Bolts Manufacturer in India.

ASTM A193 Grade B8T bolts are made using high-quality material, and these bolts are manufactured using superior technology and mechanism. These bolts are commonly used for multiple purposes, and they have high strength and flexibility, which is the most remarkable property that this grade provides. 

ASTM A193 Grade B8T bolts are highly efficient and effective for industrial and commercial uses. The strength of the grade is high, which makes it an ideal application for all kinds of purposes. This grade has great resistance from inter-granular corrosion. 

ASTM A193 Grade B8T bolts are made from an extraordinary alloy combination, including chromium, silicon, nickel, manganese, carbon, phosphorous, etc. The grade has a high heat temperature bearing capacity. The grade includes minimum 17-19%, nickel 9-12%, silicon 1%, Manganese 2%, etc. The inclusion of all these products improves the stability and strength of the grade. 

ASTM A193 Grade B8T bolts provide great resistance from corrosion, crevice corrosion, and stress cracking. The grade also has high tensile and yield strength which increases the durability of the grade. The minimum tensile is 125 Ksi, whereas the yield strength of the grade is 100 Ksi. The ASTM A193 Grade B8T bolts include cryogenic, pressure, and sanitary applications. 

JF Engineering is one of the most astonishing manufacturers, suppliers, and exporters of all metal products. We manufacture these products using high-quality raw materials.
