Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S275ML steel supplier carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S275ML steel supplier alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

Using advanced logistics management, advanced models and management experience to increase the reliability of logistics operations and provide customers with 24/7 cargo management. On the premise of reducing transportation and management costs as much as possible, we provide customers with high-quality and efficient services; good business reputation has been recognized and supported by our customers.

Our company produces ordinary carbon steel S275ML steel supplier with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a S275ML steel supplier production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic S275ML steel supplier 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 S275ML steel supplier steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
