Most common A572 Gr 60 high strength steel steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled A572 Gr 60 high strength steel steel plates.
According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic A572 Gr 60 high strength steel steel exports to 2.44 million tons, down 2.4 percent year on year, after January down 3 percent, the second consecutive month of decline. In the past three years, South Korea's steel exports have decreased year by year, from 31.67 million tons in 2017 to 30.44 million tons in 2018 and 30.38 million tons in 2019. Instead, South Korea's A572 Gr 60 high strength steel steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of A572 Gr 60 high strength steel, SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.
