EN10025-6 S690 steel is a quenched and tempered high-strength non-alloy steel plate. The series of grades are S690Q, S690QL, and S690QL1. They are in accordance with the European standard EN10025-6. The steel specified in this standard can be used for the production of hot-rolled plates with steel grades SA283 grade C carbon steel plate sheet, S460, S500, S550, S620, S690, S890, S960 series steel plates with a minimum nominal thickness of 3mm and a maximum nominal thickness of ≤150mm.

SA283 grade C carbon steel plate sheet, low alloy high strength steel has good atmospheric corrosion resistance and is widely used in engineering structure construction. Most of the engineering structures are used in the atmosphere or marine environment. A small amount of Cu, Ni, Cr, P and other elements are added to the low alloy high strength steel, which effectively improves the corrosion resistance of the engineering structure in the atmosphere, sea water and soil. If 0.2% - 0.5% copper, 0.05% - 0.1% phosphorus and aluminum are added, the corrosion resistance of steel can be improved obviously, and the effect of adding copper and phosphorus at the same time is the best.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and SA283 grade C carbon steel plate sheet steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and SA283 grade C carbon steel plate sheet medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for SA283 grade C carbon steel plate sheet, 42CrMo steel is quenching and tempering.
