19Mn6 pressure vessel steel Description

19Mn6 pressure vessel steel plate is a German standard grade of high temperature structural steel, which complies with DIN17155 standard. The equivalent materials of 19Mn6 are national standard Q345R and European standard P355GH. 19Mn6 steel plate has good heat resistance, oxidation resistance, alkali resistance and corrosion resistance, high strength and durable fracture plasticity. 19Mn6 high temperature and high pressure boiler steel plate is mainly used in petroleum, chemical industry, power station, boiler, high temperature pressure vessel, pressure parts and other industries.

DIN 17155 19Mn6 heat-resistant high-pressure boiler steel can show characteristics under high temperature, local temperature up to 600 ° C, and time load. The delivery status of 19Mn6 steel plate is hot rolling and normalizing, the normalizing temperature of heat treatment is 890-950 ° C, and the stress relief annealing is 520-620 ° C. BBN Steel can provide 19Mn6 pressure vessel steel plates of various sizes, and provide cutting and deep processing services according to customer needs to meet customer requirements.
