19Mn6 Heat-Treated PVQ Steel Plate
19Mn6 high pressure vessel is high temperature and high pressure resistant boiler steel plate, which implements the German standard for high temperature structural steel.
19Mn6 high temperature pressure vessel has good mechanical properties at room temperature and high temperature, anti-oxidation and alkali corrosion resistance, sufficient endurance strength and endurance fracture plasticity, so it is widely used in the production and use of boiler ladle coil in power station.
