BBN company can cut and assembly steel materials normal strength hull structural steel GL-B according to the requirements of use to make various structural parts and mechanical parts. It can also be made into welded section steel to further expand the use range of steel plates like factory steel structures, pressure vessels, oil storage tanks, packing boxes, train boxes, automobile shells, industrial furnace shells, etc.
Last week, the price of China's imported iron ore rose first and then fell. The external disk price was basically the same as the previous weekend, and the spot ore price at the port dropped by 10 yuan/ton to 30 yuan/ton. Due to the stricter environmental protection in Tangshan area and the hindrance of port transportation, the willingness of local steel mills to purchase iron ore declined, and the consumption of lump ore and pellet ore was slightly increased.
Hot rolled normal strength hull structural steel GL-B product stock size: 12*1600*91000, 25*1950*10250, 25*1950*10150, 14*2000*10000, 12*1600*10000, 16*1500*9340, 60*2020*6100, 25*1950*9700, 14*2000*13500, 75*2390*4320, 16*1500*9340, 50*2740*13460, 20*2100*10700, 20*2500*6200, 60*1750*9100, 34*1900*12000, 12*2050*5100, 45*2010*10000, 25*2100*8650, 70*2270*7600, 16*1500*9340, 6*1950*10000, 30*2000*7630, 20*2100*11600, 70*2260*7950, 34*1900*12000.
High-strength hull structural steel is divided into strength grades according to its minimum yield strength, and each strength grade is divided into A, D, E, F4 grades according to its impact toughness. The yield strength of ship plate materials A32, D32, E32, F32, normal strength hull structural steel GL-B is not less than 315MPa.
