5'x12' tolerance hardness of S690QL plate size

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, hardness of S690QL flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

High quality structural steel thick plate product hardness of S690QL dimension(mm): 40*2300*12000, 50*1780*7000, 16*2300*12000, 50*2500*10120, 55*1800*11900, 25*2300*12000, 50*2500*10060, 60*2500*8400, 60*2100*10000, 80*1920*6000, 130*2200*10000, 140*2200*10000, 55*1800*11550, 110*2320*8100, 40*1900*7350, 150*2200*10000, 45*2200*9000, 60*2500*8300, 40*2300*12000, 90*2440*12400, 125*1920*5000.

Hyundai Steel Co. has no plans to cut production further despite weak steel demand due to the coronavirus pandemic, the company's president said. Earlier this year, South Korea's second largest steelmaker reduced its hardness of S690QL annual production of hot rolled coils from 1 million tons previously to 700 thousand tons per year for EAFs. A turnaround is expected after the third quarter of this year.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for hardness of S690QL and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
