What is the heat treatment of SA302GrC steel plate?

SA302GrC steel belongs to manganese molybdenum nickel alloy steel plate for pressure vessels.

Heat treatment process: when the SA302GrC plates thickness is less than 50mm, hot rolling, normalizing, normalizing + stress relief treatment can be selected.

When the SA302GrC plates thickness is greater than 50mm, the delivery status is normalized. When the steel plate with a thickness greater than or equal to 100mm is delivered in normalized condition. It can be accelerated by a blower or liquid quenching and then tempered in the temperature range of 1100-1300 ° F (595-705) Mechanical properties near fire.
