A great article by Randy Schmitz of Calgary Fire Department about boron and other high strength steel used in the automotive industry. He has a good list of cars and SUVs that have boron and some other great information. Here’s a little, but check the link for the whole article.
The strength of this boron metal that is in the late-model Volvo XC90 has a tensile strength of approximately 195,800 psi.Subaru has added eight layers of medium heavy steel in its B-pillars, along with 3/4-inch (19-millimetre) steel round bars welded inside the core of the pillar to increase strength. Also, one middle layer of this pillar is exotic metal to further reinforce the pillar.
A few other vehicles with these types of similar reinforcements in
their safety cages include:
- Porsche Cayenne 2002-2007
- Audi Q7 2006-2007
- Volkswagen Touareg 2002-2007
- Ford–Five Hundred 2005-2007
