Description

The soft non-alloy steel St 4 is suited for cold forming and is offered in different conditions (K to K60) with different strength and depth indications. The steel is applicated in the plant and tool engineering. Free from stretcher lines for 4 weeks is garuanteed in the LG and K32 condition. No stretcher lines occur in the conditions K40 to K60. The steel is weldable, in the conditions K32 to K60 the strength can be decreased post welding.
