1.0338 (DIN 1623-1 : 1983-02) St 14 1.0338 DIN 1623-1 : 1983-02 DIN 1623-1 : 1983-02 replaced by DIN EN 10130 : 1999-02 Replaced Germany DC04 1.1.1 1)
1) Remark: The soft non-alloy steel St 14 (St 4 acc. to DIN 1624) is suited for deep drawing of complex shapes, also at higher sheet thicknesses and high demands in the formability. The steel is weldable and the base material for - electrolytic coated sheet and strip - hot-dip coated sheet and strip - varnished sheet and strip - plastic-coated sheet and strip - composite material (metal-plastic-metal).
