L7 alloy steel stud bolts for low-temperature service — cryogenic and sub-zero piping applications.
L7 stud bolts to ASTM A320 are specified for low-temperature and cryogenic service — applications where standard B7 studs risk brittle failure at sub-zero temperatures. L7 is impact-tested at low temperature to confirm toughness under cold conditions.
