ASTM A320 L7/L7 High Strength Low Temperature Studs

A320-L7 is an American standard low-temperature alloy steel material with a chemical composition approximately equal to 42CrMoA, but some elements are slightly different. SA320L7 belongs to ultra-high strength steel, which has high strength and toughness, good hardenability, no obvious tempering brittleness, high fatigue limit and resistance to multiple impacts after quenching and tempering treatment, and good low-temperature impact toughness. Suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.

A320-L7 is an American standard low-temperature alloy steel material with a chemical composition approximately equal to 42CrMoA, but some elements are slightly different.

In terms of mechanical performance, there is basically no difference, but there are significant differences in the use of nuts. The application situation is that b7 is an ultra-high pressure and high temperature Bolt material, while l7 is a lower temperature bolt material. In addition, there may be some differences in the composition of chemical elements.
