2020-06-18 19:32:55
Brief Introduction of SA387
SA387 GR11 22 American standard chromium molybdenum alloy steel plate for pressure vessel
Uses: SA387-11 corresponds to 15CrMoR, used in petroleum, chemical, power station, boiler and other industries, for manufacturing reactors, heat exchangers, separators, spherical tanks, oil and gas pipes, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, Liquefied petroleum gas cylinders, high-pressure water pipes for hydropower stations, turbine volutes and other equipment and their construction
There are different grade under this standard:
A387 GR2
A387 GR12
A387 GR11
A387 GR22
A387 GR22L
A387 GR21
A387 GR21L
A387 GR5
A387 GR9
A387 GR91

It is so called alloy steel, which is able to have 13% refund duty, which means lower price for client in oversea market.
