Low Alloy High Strength Pickled Steel Strip for Cold Forming

Low Alloy High Strength Pickled Steel Strip for Cold Forming is a type of steel that has been specifically designed to provide high strength and good formability. The pickling process involves removing any surface scale or oxide layer to provide a clean surface for further processing. The resulting steel strip can be cold-formed into complex shapes without cracking or splitting, making it ideal for applications in the automotive, construction, and manufacturing industries.
