p355gh steel used for petroleum surface cracks refer to the linear cracks on the surface of p355gh steel used for petroleum, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: p355gh steel used for petroleum surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

We have a lot of advantages for p355gh steel used for petroleum steel plate processing. First, we have huge steel plate stock. That not only saves material preparation time, but also saves much transportation cost. Second, we have professional technical team, who can design drawing according to client requirements quickly. Or if clients have drawing, we can communicate and make it clear soon. Third, we have built special steel processing center. The professional and experienced work will make you more satisfied and at ease.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the p355gh steel used for petroleum steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the p355gh steel used for petroleum weathering steel is purified and the content of inclusions is greatly reduced.

p355gh steel used for petroleum discount steel plate and sheet (size mm) supply: 10*2200*12000, 18*2000*000, 14*2000*12000, 22*2500*1000, 12*2000*11000, 16*2500*10000, 14*2000*11000, 25*2000*10000, 12*2000*12000, 14*2500*10000, 14*2000*10000, 20*2500*10000, 12*1800*10000, 16*2200*000, 14*2000*9000, 22*2200*1000, 12*1800*9000, 16*2000*10,000, 16*1800*10000, 14*1800*9000, 20*2000*10000, 22*2200*10000, 30*2500*10000.
