The soft non-alloy steel RRSt 3 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.

This material data has been provided by WIAM.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
