S890QL steel plate market heats up again

S890QL steel plate surface cracks refer to the linear cracks on the surface of S890QL steel plate, 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: S890QL steel plate surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with S890QL steel plate ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent S890QL steel plate products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the S890QL steel plate technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and S890QL steel plate general weldments that do not need heat treatment.
