Q370R

Q370R Pressure Vessel Steel Plate

 

GB 713 Q370R Pressure vessel steel plate shall be done Normalized heat treatment normally when rolling.The ultrasonic examination is necessary for all pressure vessel steel plates. Q370R Pressure vessel steel plate has the advantages that: the mixing ratio of the components and the heat treatment process are optimized. Q370R steel sheet has the advantages that: the mixing ratio of the components and the heat treatment process are optimized; the low-temperature impact toughness is improved on a basis that the tensile strength and the yield strength meet the standard GB 713-2008.

Q370R Pressure vessel steel sheet is widely used in petroleum, chemical industry, power plants, boilers and other industries for the production of reactor, heat exchanger, separator, spherical tank, oil tank, LPG tanks, pressure vessel, boiler drum, liquefied petroleum gas cylinders, Hydropower high-pressure water pipes, turbine scroll case, others equipments and components.
