13MnNiMoR boiler steel
13MnNiMoR pressure vessel quality steel is a kind of steel plate for medium and low temperature pressure vessel, which is implemented in GB713.2-2023 standard.
13MnNiMoR boiler quality plate has good strong and tough performance, welding performance, internal quality, resistance to HIC and hydrogen sulphide corrosion, and meets the requirements of low welding crack sensitivity.
13MnNiMoR pvq plate is widely used in petroleum, chemical, power station, boiler and other industries because of its high strength, toughness, corrosion resistance and oxidation resistance.
