Selecting ASTM A320 Grade L7 Stud Bolts
ASTM A320 Grade L7 is a quenched-and-tempered alloy-steel stud-bolting grade used where low-temperature toughness is required. When specifying L7 studs for pipeline flanges, pressure equipment or LNG-related service, confirm the governing piping/equipment code and the minimum design metal temperature. Required impact-test temperatures, mechanical testing, heat treatment and documentation must be checked against the applicable material standard, purchase specification and supplied heat or batch.
L7 Stud Sizes, Nuts and Finishes: Buying Checklist
- ASTM A320 Grade L7 designation, diameter, thread series/pitch and overall stud length
- Quantity and whether nuts and washers are required per stud
- Matching nut grade (such as ASTM A194 Grade 7 or 2H) as approved by the project specification; do not assume grades are interchangeable for every duty
- Required coating or surface finish, service temperature and corrosion conditions
- Material test certificates, impact-test evidence, traceability and inspection requirements, where specified
