ASTM A320 Grade L7B, ASTM A320 Grade L7B Bolts/Screws/Studs, 8740 Alloy Steel, Hex Bolts, Hex Cap Screws, ASTM A320 Gr L7B Fasteners Manufacturer
Ananka Group is one of the best ASTM A320 Grade L7 Stud, Bolts, Nuts, Screws & Washers Manufacturer Supplier & Stockists in India. ASTM A320 Grade L7B Bolt / Stud Bolts are manufactured using ASTM A320 Grade L7B material, which is desirable to manufacture fastener products bolts, studs and nuts, that can be used at a varied range of elevated temperatures in bolting applications. ASTM A320 Grade L7B is the most common grade of A320 bolts. Bolts made using this material are extremely resistant to corrosion and a varied range of environmental conditions. Steel alloyed with chromium, manganese, and molybdenum are used to make ASTM A320 Grade L7B Bolts and threaded studs. To achieve the requisite mechanical qualities, the bolts are subjected to a heat treatment process.
ASTM A320 L7B Stud Bolts are designed for low-temperature applications. Valves, flanges, fittings, and pressure vessels are all popular uses for these fasteners. The minimum Charpy impact value for ASTM A320 L7B Stud Bolts is 20 ft-lbf @ -150F, according to ASTM regulations. The Charpy impact test determines the overall amount of energy absorbed by a material during fracture, revealing the notch toughness of the material.
The tensile and yield strengths of the ASTM A320 L7B Stud Bolts vary. The minimum tensile strength varies by grade within the A320 specification, ranging from 75ksi to 125ksi. The minimum yield strengths of the A320 bolts and nuts range from 30ksi to 105ksi, with elongation rates ranging from 12% to 30%. Carbon, manganese, phosphorus, sulphur, silicon, chromium, nickel, and molybdenum all have a role in the material makeup of the various grades. The astm a320 l7m nuts have chromium concentrations of up to 18%, nickel concentrations of up to 14%, and molybdenum concentrations of up to 3%.
