Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
S50C steel plate is a high-quality high-quality medium carbon steel. S stands for steel, which means iron, and 50 stands for carbon content of 0.50%. C represents carbon steel, which means that S50C is a carbon steel with a carbon content of 0.50%.Mechanical properties of S50C steel plate:Tensile strength σb (MPa): ≥630 (64); Yield strength σs (MPa): ≥375 (38); Elongation δ5 (%): ≥14; Reduction of area ψ (%): ≥40; Impact Work Akv (J): ≥31(4); Impact toughness value αkv (J/cm2): ≥39(4)Hardness: unheated, ≤241HB; annealed steel, ≤207HB

Alloy plate, A283 grade D mild steel coil boiler plate, container plate, carbon plate, open plate, I-beam, angle steel, channel steel, H-beam, round steel, steel pipe, hot rolled coil, cold rolled galvanized and other spot stocks.
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 A283 grade D mild steel coil 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.
