ASME SA 320 Grade L7M Hex Bolt and Astm A320 Gr L7m Threaded Rod Manufacturer In India

Alloys that are suited to low temperatures need to withstand expansion or contraction with a change in the temperature of the ambiance. There needs to be room for the alloy to permit both expansion or contraction depending on the heat available in the surrounding. Carbon steels that are hard, service at low temperatures is difficult because they would become brittle, thus leading to cracks. However, unlike conventional carbon steel alloys, the ASTM A320 L7 Stud Bolts have sufficient ductility, making them suited to withstand the change in temperatures.

ASTM A320 L7 Stud Bolts

Alloy steels have a higher ductility with hardness valued at an optimal level. The content of manganese, chromium, and molybdenum are added as primary alloyants in the material. These properties lend superior mechanical characteristics to the A320 Grade L7 Bolts in comparison to ordinary carbon steel alloys. Tension tests performed on these specimens are used to determine the conformance of the ASTM A320 Grade L7 Nuts to this specification. The material is tested for impact energy absorption at suggested controlled temperature settings. This test aids in evaluating the amount of energy that is absorbed by the ASTM A320 Grade L7m Bolts in total during fracture. To simplify this, the Charpy test is used to understand the notch toughness property of the alloy. Since alloys are very likely to develop stress in low temperature environments, this specification calls for different mechanical tests. ASTM A320 Grade L7 Stud Bolts are subjected to tests like hardness, impact test, and tension test. Typically, these fasteners are used in the assembly of pressure vessels. The ASTM A320 Grade L7 Nuts may also be used to forge connections in piping systems, flanges, valves, and fittings.
