ASTM A320/A320M L7
Designed for low temperature applications. Similar chemical and mechanical properties as the A193 B7,however the material is also required to be impact tested at-150F.
设计用于低温应用。化学和机械性能与A193 B7类似，但材料还需要在-150F进行冲击测试。
ASTM A320/A320M L7M
Designed for low temperature applications. Similar chemical and mechanical properties as the A193 B7M,however the material is also required to be impact tested at-100F.
设计用于低温应用。化学和机械性能与A193 B7M类似，但材料还需要在-100F进行冲击测试。
ASTM A320/A320M L43
Designed for low tmperature applications. A 4340 alloy steel with similar mechanical properties as the L7,but with better cold-temperature impact properties particularly at larger diameters.
设计用于低温应用。一种4340合金钢，具有与L7类似的机械性能，但在较大直径下具有更好的低温冲击性能。
