Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized RINA FH36 ocean engineering steel are higher than that of annealed RINA FH36 ocean engineering steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of RINA FH36 ocean engineering steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic RINA FH36 ocean engineering 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 RINA FH36 ocean engineering steel steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
