ASTM A320 Grade L7M
ASTM A320 is a fastener standard defining chemical, mechanical, and heat treatment requirements for bolts & studs including carbon steel, alloy steel and stainless steel grades for low temperature & cryogenic service
Description of Material
ASTM A320 L7M is manufactured from AISI 4140 base material and is supplied in a quenched and tempered condition. Due to the impact requirements at low temperature, it is mainly used in a low temperature environment or application but differs from ASTM A320 L7 due to it having a further temper or stress relieve after final machining, to reduce the overall hardness for use in sour/specific applications.
Lonestar can offer this material in a standard condition, or it can be provided with supplementary testing as defined in ASTM A320. This material can also be offered fully in compliance to the additional requirements of API 20E BSL 1, 2 and 3.
