What should concern during the production and processing of nm550 steel chemical composition

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

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

NM550 steel chemical composition,Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores stainless steel and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.

NM550 steel chemical composition,As alloy 400 is a kind of metal with good corrosion resistance, it shows good uniform corrosion resistance in the marine atmosphere. This is because alloy 400 can form a very thin and tough protective film. Uniform corrosion is one of the easiest forms of corrosion to deal with, because engineers can quantitatively determine the corrosion rate of metals and accurately predict the service life of metals.
