A573 Gr 70 structural carbon steel sheet, No. 55 steel is a fully static steel manufactured by the electric furnace, open hearth or pure oxygen converter steelmaking method. It has the characteristics of excellent workability and uniform metallographic structure. A573 Gr 70 structural carbon steel sheet, No. 55 steel is cheap and easy to process, and is suitable for surface hardening treatments such as high frequency quenching and flame quenching.
According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic A573 Gr 70 structural carbon steel sheet 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 A573 Gr 70 structural carbon steel sheet steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A573 Gr 70 structural carbon steel sheet plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A573 Gr 70 structural carbon steel sheet, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
