Comment by Larry Montanez on November 9, 2011 at 6:11pm @Jason Lee Gulick, Liht weight steel is an incorrect term. There is no such thing as a light weight steel. Steel is heavy, but the higher strength steels are stronger and lighter than the lower strength steels so essentially the vehicle weight drops but retains a higher degree of strength. Boron is also an incomplete term. Boron is an alloy that is introduced into a Martensite steel (Quenched) that produces a yield strength of equal to or greater then 1000 MPa (145,037.8 psi). Generally this type of alloyed steel is used by OEM's in areas where the ultimate strength is required, such as in A, B, C-Pillars Reinforcements, Rocker Panel Reinforcements, Floor Crossmembers, seat assembly crossmemebers and in areas of stress to limit torsional movement. Boron alloyed steel CANNOT be heated, straightened or galvanized. Extreme care must be taken when repairing areas where Boron alloyed or Martinsite steels are located as collateral damage to adjacent components could occur. Generally steel with a 600MPa yield strength will require replacement. So techs will not have an issue straightening but will have to learn that additional anchoring and straightening procedures will be required. OEM's like Mercedes Benz call Boron alloyed steel Usi-Bor while Volvo calls it Boron steel (Boron is trademarked by a steel company), Audi calls it Ultimate steel. Structural repair technicians must learn that they need to check with the OEM (or ALLDATA) to obtain the yield strength of the material they are working on as European OEM's use different classifications for HSS and UHSS then Asian and USA OEM's.

We do offer low cost and free classes to trade schools and non-for-profits (usually we just ask for travel/lodging costs).
