As the thickness and hardness of 150mm GL-DH 36 TM rolled steel increase, the tendency to crack at the cutting edge increases. In order to prevent the 150mm GL-DH 36 TM rolled steel from cutting cracks, preheating should be carried out before 150mm GL-DH 36 TM rolled steel cutting. Special attention should be paid to preheating to make the entire 150mm GL-DH 36 TM rolled steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole 150mm GL-DH 36 TM rolled steel cannot be preheated, the partial preheating method can be used instead.
In terms of inventory, the recent arrival of new 150mm GL-DH 36 TM rolled steel resources is relatively small. Due to the high ordering cost, the weakening of merchants' purchasing enthusiasm, and the rapid production of steel mills, resulting in the shortage of some 150mm GL-DH 36 TM rolled steel specifications. On the whole, the market has a strong wait-and-see mood. The ex factory prices of steel mills are strong and some resources are in short supply. It is expected that 150mm GL-DH 36 TM rolled steel prices will continue the high consolidation operation tomorrow.
Plate 20 to 30mm thick 150mm GL-DH 36 TM rolled steel product: 20*1400*11400, 20*2100*7000, 20*2500*6200, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480, 22*3400*13000, 23.1*2590*7790, 25*1950*10150, 25*1950*9700, 25*2100*8400, 25*2100*8650, 25*2400*11600, 25*2400*8200, 28*2170*13000, 30*1600*10720, 30*1600*8600.
At present, BBN steel has successfully developed Grade D40, E40 and other high-strength and high-toughness structural steel plates for offshore engineering, E550 and other quenched and tempered ultra-high-strength offshore platform steels, 150mm GL-DH 36 TM rolled steel, API 2W Gr50 and other TPCP platform steels, and DH36-Z35 offshore oil platform steel, SM490, SM400 series of H-shaped steel for offshore oil platforms, etc., basically formed the serialization of high-strength steel for offshore platforms.
