p295gh steel material 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 p295gh steel material 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.

General Administration of Customs: China's p295gh steel material and so on steel export in December was 4.684 million tons. According to data released by the General Administration of Customs on Tuesday, China's steel imports in December 2019 were 1.483 million tons, and the total imports in 2019 were 12.304 million tons, down 6.5% from 1316.6 in 2018. China's steel export in December 2019 was 4.684 million tons, and the annual export volume in 2019 was 64.293 million tons, 7.3% less than 69.335 million tons in 2018.

p295gh steel material annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of p295gh steel material annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. p295gh steel material annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
