Chemical properties of 09MnNiDR pressure vessel plate
09MnNiDR vessel plate is a high-quality steel plate designed for cryogenic pressure vessels. It has good tensile strength, yield strength, elongation and low-temperature impact toughness, and can maintain high impact toughness at -70℃.
09MnNiDR boiler steel is widely used in low-temperature storage and transportation equipment in the petroleum, chemical, natural gas and other industries, such as deethanizers, CO2 absorption towers, cryogenic storage tanks, etc. At the same time, 09MnNiDR is also suitable for manufacturing fields such as nuclear power, marine equipment and compressor casings.
