More cheaper A283 Gr C carbon steel plate sheet sheet for sale

S890 steel is a quenched and tempered high-strength steel plate, the series grades are S890Q, S890QL, S890QL1. S890Q, S890QL, S890QL1 steel,A283 Gr C carbon steel plate sheet plates, where S means structural steel, Q means that the impact temperature of the steel plate is -20°C, and QL means that the impact temperature of the steel plate is -50°C.Then guess what QL1 stands for. QL1 means that the impact temperature of the steel plate is -60°C, and 890 means that the thickness is £50mm.

Ordinary medium and thick steel plate A283 Gr C carbon steel plate sheet is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.
