SA662 GrC steel plate for boilers and pressure vessels

Detailed explanation of SA662 GrC steel plate:
SA662 GrC steel plate is an American standard steel plate for boilers and pressure vessels, which can be used to manufacture low temperature pressure vessels, and SA662 GrC steel plate has good welding performance, which can be used to manufacture welded pressure vessels.

The production process of steel plate is:
1. electric furnace smelting
2.refining
3.ingot casting
4.Ingot
5.heating ingot
6.steel rolling
7.flaw detection
8.heat treatment normalizing
9.warehousing.
This is a relatively omitted refining step, which will be a little more complicated.
