According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic low cost of NM500 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 low cost of NM500 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 secondary quenching and low temperature tempering of wear resistant composite plate are mainly used for high alloy steel workpieces without mechanical processing after carburizing. Carburizing, high-temperature tempering, one-time heating quenching, low-temperature tempering, quenching temperature 840-860℃, mainly used for Cr Ni alloy carburizing workpiece. The second quenching and low-temperature tempering of wear-resistant composite plate, low cost of NM500 steel mainly improves the microstructure of the infiltrated layer. When the requirements for core properties are not high, quenching can be performed between AC1 and AC3, and when the requirements for core properties are high, it should be quenched above AC3.
Steel plate is a plate-shaped steel formed after pouring molten steel. Steel plate is one of the most common forms of steel. With the diversity of market demand, steel plate styles have become diverse, mainly including thick steel plate, thin steel plate, flat steel, etc. Among them, thick steel plate is mainly used in building construction, ship plate, vehicle, boiler, high pressure vessel, oil and gas pipeline, large steel structure, etc. The requirements for bearing capacity of low cost of NM500 steel, thick steel plate are very high.
