A194 Gr 8c Material manufacturer in India
ASTM A194 Grade 8C Nuts are made up of martensitic alloy stainless steels with sizes ranging from ¼ inches through 4 inches. The nominal sizes range from M6 through to M100 in metric scale. Viha Steel & Forging is a leading SA194 Gr. 8C Heavy Hex Nuts manufacturer and supplier. The heavy hex nuts are used in high strength and high torque applications where the use of tools enables maximum tightening of the fasteners.
The Gr 8C Washer and other fasteners are intended for high temperature services with high pressure services as well. The material is made up of the 347 grade steel. The composition has 17% chromium, 9% nickel with carbon, manganese, phosphorus, sulfur and silicon in the A194 Gr 8c Material. The fasteners are forged either hot or cold and machined from the 347 heat treated bar stocks. The bars are also quenched and tempered to increase the hardness up to 223 BHN. The ASTM A194 Grade 8c Nuts range up to 550MPa minimum tensile strength, the minimum yield strength is 240MPa.
The elongation rate of the fasteners is 30%. The fasteners are used in oil and gas, petroleum, petrochemical, power generation and other applications. The different types such as the ASTM A194 Grade 8C Washer are used to fasten components in heavy applications with high temperature and pressure conditions. As a leading supplier, we produce the fasteners in various types, shapes and sizes. Please feel free to contact us for more information on the different types such as the ASME SA 194 Gr 8C Nut and the prices.
