The tooling alloys which have been used for decades, such as D2, A2 or S7, are reaching their load limits and often result in unacceptable tool life. The mechanical properties of the sheet steels achieve tensile strengths of up to 1800 MPa with elongations at the break of up to 40%. Additionally, the tooling ahss fundamentals in forming and joiningThe importance of local formability when working with AHSSWhen R/t is large enough, conventional necking thinning will occur outside the radius off the tangent, which is predictable with most forming simulation packages. According to the AHSS Application Guidelines 6.0, for product features such as embossments on parts made from DP600 or stronger, the R/t should be at least 3T. For the same material grades, if the sheet steel is pulled over a punch radius or
