... or discussed. Because the modulus of elasticity is the same for all steels, downgaging reduces component stiffness. Also, because corrosion resistance of AHSS (except for austenitic stainless steel) is similar to that of mild steel, thinner gages rust faster under the same corrosion conditions. Problems...
