Q345R (R-HIC) steel plate, used for manufacturing low pressure separator. The low-pressure separator uses a wet hydrogen sulfide solution to operate in the environment. Q345R (R-HIC) steel plate adopts five welding processes to ensure its corrosion resistance.
Stress corrosion and hydrogen cracking tests are required for all five welding procedures to prevent safety incidents. Q345R (R-HIC) stress corrosion cracking test was carried out by four-point bending method in GB/T4157-2006 and ASTMG39-2005 standards, and hydrogen-induced cracking test was carried out according to GB/T8650-2006 standards.
Q345R (R-HIC) steel plate, boiler container plate, is widely used in petroleum, chemical industry, power station, boiler and other industries, generally used in the production of reactor, heat exchanger, separator, pipe, liquefied gas tank, boiler gas bag and liquefied petroleum gas cylinder.
