With its formability and ductility, SA588 Grade K alloy is easily formable, hence it is ideal for cold forming operations. Additionally, with the composition of alloying elements, it implies for most powerful processing equipment compared to standard grades. All standard welding process can employ on plates. It has a homogenous structure with a uniform distribution of alloying elements. As a leading low alloy steel plate supplier, we can supply low alloy steel plate SA588 Grade K, sheet SA588 Grade K price directly.
