Even though HSLA material is thinner than the steel it is What are the effects of switching to HSLA steel?What are the effects of switching to HSLA steel?The main effect of switching to a HSLA material on the coil line is on the straightener/leveler requirements. Eliminating material coil set requires a larger straightener with a larger roll diameter, increasing the number of backups to the straightening rolls, or perhaps switching to a precision leveler.Challenges, solutions for forming HSLA steel What kind of force is needed to form HSLA steel?What kind of force is needed to form HSLA steel?Obviously, higher forming force is required to form a HSLA part with the same dimensions as a mild steel part. This requires larger-tonnage presses. Another factor increasing tonnage loads is the requirement for higher draw pad pressure.Challenges, solutions for forming HSLA steel

What should bed and slide deflection be for HSLA steel?What should bed and slide deflection be for HSLA steel?When an operator is blanking, it is recommended to have a press with bed and slide deflection of 0.001 inch per foot or better. Also, the overall stackup clearances of the press should be measured. This can be done by maximizing the counterbalance pressure, dropping it to zero, and then measuring the change in die height.Challenges, solutions for forming HSLA steel(PDF) Formability Analysis of Diode-Laser-Welded Tailored Challenges solutions for forming HSLA steel
