low alloy and high strength steel plate S355J2G3
The characteristics of Wugang special thick steel plate
1. High purity of steel quality:[p]≤100ppm,[s]≤30ppm,[o]≤20ppm,[n]60ppm,[h]≤2ppm,Folder with low impurity content.
2.Good internal quality:Flaw detection to meet the grade I standard JB/T4730,GB/T2970 and SEL072, EN10160 standard S3T4,ASTM,A578, grade C and grade I standard jb/t8467, and grade I standard gb/t6402, to reach the rolling instead of forging.
3.Uniform composition and performance: the difference of the composition organizations, and the performance of steel plate at different positions is small, which for user-friendly.
4.Low-fold organization is dense: Dense, segregation, porosity degree is light
5. Excellent welding performance:By improving the smelting process, adjusting the amount of alloy in the steel, to further reduce the value of Ceq and Pcm, which is easy to welding performance.
6 .Plate-shaped appearance of the straight: it can achieve the flatness≤3mm/m, it is ease to cut as production use.
