ST12/ST13/ST14/ST15 steel strip
Both ST12 and ST14 are cold-rolled steels, but their application levels and mechanical properties are different. ST12 is the most common steel grade, which is basically the same as q195, SPCC, and DC01 grades. The yield strength of ST12 is aMPa≤280; the tensile strength is MPa≤270～410; the elongation after fracture (L0=80mm, b=20mm)%≥28. ST14 is a deep-drawing grade cold-rolled steel, which means it can withstand greater deformation without breaking, and is suitable for occasions with higher requirements for ductility.
