Spring flat steel for automobile Q195, Q235B, Q345B
Flat steel refers to a steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and slightly dull edges. 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. Main use: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and used as house frame structural parts and escalators in construction.
The product specifications are special. The thickness is 8-50mm, the width is 150-625mm, the length is 5-15m, and the product specifications are relatively dense, which can meet the needs of users. It can be used instead of the middle plate and can be directly welded without cutting.
The surface of the product is smooth and clean. The high-pressure water descaling process is used twice in the process to ensure the smooth and clean surface of the steel.
The sides are vertical and the water chestnuts are clear. The second vertical rolling in the finishing rolling ensures good verticality on both sides, clear corners, and good surface quality on the sides.
The scale of the product is accurate, three-point difference, the same level difference is better than the steel plate standard; the product is straight and the plate shape is good. The finishing rolling adopts continuous rolling process, automatic looper automatic control, to ensure that no steel is piled or stretched, the product size is high, the tolerance range, three-point difference, same stripe, sickle bend and other parameters are better than the medium plate, and the plate shape is straight. Degree is good. Cold shearing, high precision of length setting.
