ISO certified steel production nm500 material mechanical properties Company

RAEX400 steel is a hardened wear-resistant steel material with an average grade of 400HBW and a Brinell hardness. The microstructure of this wear-resistant steel is a martensite structure, which can ensure the high hardness and tensile hardness of the steel plate. The hardness of RAEX400 is 2.5 times that of S355 structural steel, NM500 material mechanical properties. Despite its high hardness and high strength, RAEX400 steel can be formed by free bending or hemming, and has good weldability.

Phosphorus is a very harmful element in NM500 material mechanical properties steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of NM500 material mechanical properties steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

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