Using a torch to heat and straighten frame rails can compromise the structural integrity of today's advanced metals. Cold straightening with an induction heater is the better choice.Three generations of advanced high-strength steels for introduction to advanced high strength steels part iAdvanced High-strength SteelsThe First Generation First-generation AHSS have more formability than HSLA at the same strength level. These steels typically have a martensitic microstructure, sometimes with one or more addi-tional phases to improve formability. Martensite is the hardest and stron-gest form of steel, but it also is theThree generations of Another strengthening mecha- T ypical advanced high-strength steels (AHSS) have limited formability that decreases even more as strength increases. Thus, over a strength level of 1,000 to 1,200 MPa (145 to 175 KSI), cold forming of AHSS is limited to very simple geometries.
Sep 23, 2014 · Ultrahighstrength steels are extremely heat sensitive and will lose their strength if heat is applied, for straightening.
