Product accuracy
Length: 0-10mm according to the length of the steel plate
Width: Trimmed steel plate is 0-6mm, untrimmed steel plate is controlled by rolling mill
Plate shape: steel plate unevenness within 1000mm range ≤ 6mm
Stress relief through high straightening force and large deflection
Thickness: The thickness tolerance of the steel plate meets the requirements of higher precision in Table 5 of GB/T709

main feature
1. Designed with low carbon components, it has low carbon equivalent (Ceq) and cold crack sensitivity coefficient (Pcm).
2. It has good low-temperature toughness after welding, and the impact at -40°C can reach more than 50J.
3. The welded joint has good cold bending plasticity. When the steel grade is above 900MPa and the diameter of the bending center is 6 times the thickness of the steel plate, it can be bent at 90 degrees at room temperature and the outer surface of the steel plate is intact.
4. Good weld-ability, butt welding, tower welding, fillet welding, etc. of a series of steel types with medium constraints can be carried out at room temperature without preheating.
