normalized A131 EH32 thick plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of normalized A131 EH32 thick plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. normalized A131 EH32 thick plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
API 2H gr50 is carburized steel, which is usually low carbon steel with carbon content of 0.15% - 0.24%, and is used for offshore platform structure. API 2H gr50 steel is suitable for surface carburizing and hardening treatment, with good workability, small deformation and good fatigue resistance. normalized A131 EH32 thick plate, API 2H gr50 steel is used for making hull, offshore oil production platform, platform pipe joint and other structural parts.
The normalized A131 EH32 thick plate, medium and heavy steel plate can be processed for secondary processing. If the medium and heavy steel plates are not used later, the factory can process it into other plates, which will not waste resources and save cost. The overall market situation of normalized A131 EH32 thick plate, medium and heavy steel plate is unstable, and the price changes every day. If the overall price rises, you can first observe for a period of time to find out why it has risen, and you can wait until the best price to buy.
