■ Overview
Boiler steel plate SPV355 owned a higher carbon contains comparing with pressure vessel steel plate SPV315,so pressure vessel steel plate owned a higher yield strength than SPV315.Ultrasonic test is our suggestion technical requirement in rolling for boiler steel plate SPV355,it would gurantee avoiding the crack which be brought by blinster in steel plates.Besides,for the heavy steel plate SPV355,normalized heat treatment is better to adopt for improving steel property.
