The supply and demand of A515 grade 60 pressure vessel steel sheet will be weakly balanced in the short term

BBN steel A515 grade 60 pressure vessel steel sheet hot rolled plates stock: 15*2300*14500, 8*2440*4700, 8*2300*6000, 14*1524*6096, 14*2150*8400, 8*2100*6000, 14*2000*12000, 12*2335*5000, 12*2150*7700, 15*2430*7550, 14*2000*11700, 18*2000*10000, 12*1850*9000, 16*1720*10070, 22*2200*8200, 15*2000*10000, 38*2700*6000, 50*1500*6000, 60*1800*9380, 60*1750*9380, 63*2440*5700, 63*2440*6096, 70*2210*7500,80*1800*6260 .

Most common A515 grade 60 pressure vessel steel sheet steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled A515 grade 60 pressure vessel steel sheet steel plates.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of A515 grade 60 pressure vessel steel sheet etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in A515 grade 60 pressure vessel steel sheet etc. steel is strictly controlled.

On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
