P295GH steel plate is used to manufacture pressure vessel steel for petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good weldability and hot and cold processing properties. The commonly used steels are mainly low-alloy high-strength steels and carbon steels.
