The yield strength of AH36, DH36, ABS F36 hull steel plate, EH36, and FH36 Steel for high-strength hull structure is not less than 355MPa, and the tensile strength is 490 ~ 620MPa. The letter A, D, E, and F indicate the impact toughness that they can achieve at 0°C, -20°C, -40°C and -60°C respectively. The yield strength of Grade AH40, DH40, EH40, FH40 hull structural steel is not less than 390MPa, the tensile strength is 510 ~ 660MPa.
ABS F36 hull steel plate and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of ABS F36 hull steel plate and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic ABS F36 hull steel plate 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 ABS F36 hull steel plate steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
