What year did most vehicle manufactures start using the boron/ HSA metals for reinforcement in the A/B pillars? Also the boron bars in the doors, is that something they are still using? I also like the information about the brackets with the additional welds for added strength that is good information.

I also like the information about the brackets with the additional welds for added strength that is good information. Automakers have used Boron and other steels for over a decade. Now, they are just using more of it. The boron/UHSS steel bars are steel in the doors.   Some cars have a stamped impact beam like below.  Like everything, the automakers are allows looking for new ways to save weight and increase strength. This is a Plastic Side-Impact Door Beam that DuPont developed. Not sure if it is used yet.  |

I've seen still shots of, and read article's about "deadbolting". Where a deflection collision causes the boron support strut in a door of a vehicle to be forced into the A-post or B-post of the vehicle essentially "deadbolting" the vehicle's door and making a traditional door pop virtually impossible.
Have you experienced this in the field at all?
