nm500 plate application steel grade equivalent plate

The grades specified in the GB712-2011 ship and marine engineering structural steel standard are: Grade A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, AH420, NM500 plate application, DH420, EH420, FH420, AH460, DH460, EH460, FH460, AH500, DH500, EH500, FH500, AH550, DH550, EH550, FH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690.

According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic NM500 plate application 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 NM500 plate application steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.

Heat treatment is a very important process to improve the performance of NM500 plate application etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

Affected by the weak futures performance and weak spot follow-up, the steel billet price is temporarily stable. The overall growth trend of China's NM500 plate application is slowing down, and the demand in the north is lower than that in the south. Under the background of economic recovery, the demand toughness still exists, the resource inventory is tight, and the actual willingness of the spot merchants to let the price is not obvious. The price of NM500 plate application is expected to be adjusted and operated stably.
