Grade L7. This is the most common A320 bolt grade. A320 Grade L7 bolts and threaded studs are manufactured from alloy steel with chromium, manganese, and molybdenum. The bolts undergo a heat treating process to reach their required mechanical properties.

ASTM A320 Grade L7M Specification - Boltport Fasteners

ASTM A320 Grade L7M Bolts, Stud Bolts and Studs. ASTM A320 Grade L7M is a standard material specification for alloy steel bolting materials for pressure vessels, valves, flanges, and fittings for low temperature services. ASTM A320 Grade L7M is heat treated chromium molybdenum alloy steel (AISI 4140/AISI 4140H) with notch toughness properties.
