ASTM A36 and JIS G3192 steel angle A514 Gr R alloy steel plate is one of the most widely used carbon steel section in the construction industry and project. It is a low-cost material and shows the required strength property compared with other steels. It is popular also for its good weld performance, formable, and easy A514 Gr R alloy steel plate machining. Galvanizing and other treatment increases its resistance to corrosive environment.
Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. A514 Gr R alloy steel plate, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
A514 Gr R alloy steel 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 A514 Gr R alloy steel 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. A514 Gr R alloy steel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
