ASTM A36 and JIS G3192 steel angle A573 Gr 70 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 A573 Gr 70 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. A573 Gr 70 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.
Titanium microalloying is an element of A573 Gr 70 plate strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in A573 Gr 70 plate tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
