ASTM A194 Grade 8M Class 2 Nuts and Washer

Suppliers and manufacturer of Asme SA 194 Gr 8M nuts with Exceptional sizes, standard, and Quality

ASTM A194 Grade 8M Nuts range from M02 to M160 sizes and the length ranges from 3mm to 200mm. Viha Steel & Forging is a leading manufacturer of the different types of the ASME SA 194 Gr 8M Nut fasteners. The material used for the making of these fasteners is made up of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel and molybdenum in the composition.

There are different fasteners such as the ASTM A194 Grade 8M Washer and other internally threaded fasteners. This specification covers the forged and machined internally threaded fasteners that are used in high pressure and high temperature applications. The SA 194 Gr 8M Nut gets the strength, corrosion resistance and the hardness from this material composition. The minimum tensile strength is 550MPa, the minimum yield strength is 240MPa and the elongation is 30% for the ASTM A194 Grade 8m Class 2 Nuts and the class 1 nuts.

The class 2 has higher hardness than the class 1 because of the strain hardening on top of the carbide solution treatment. The hardness of the A194 Grade 8M Heavy Hex Nuts ranges up to 223 BHN. The fasteners can be used in high temperature and high pressure applications such as the petroleum, oil and gas, power generation and in heat exchanger and boiler applications. Please feel free to contact us for more information on the different types such as the Asme Sa194 Grade 8m nut and others with pricing.
