Chromoloy tubing is made from a family of low alloy steels that contain chromium and molybdenum sae 4130 or 4140 along with the iron carbon and other elements.
Chromoly roll cage wall thickness.
A nascar cage is built completely differently than an average offroad cage.
Yes nascar may use 95 wall tube but as i understand they require chromoly which is a whole different ball game than dom or hrew.
The cage we selected comes with.
But you have to use larger sticks of tubing or more wall thickness and it costs you weight.
Also while a chromoly cage is typically lighter due to its lower minimum wall thickness it can only be tig welded while mild steel can be tig or mig welded though the welds need to be clean complete without holes and show no signs of grinding.
The cage chassis are one in the same.

The chromium adds strength hardenability and a level of corrosion resistance to mild carbon steel though chromoly is not as corrosion resistant as stainless steel.
You can make a cage out of mild steel dom tubing that is just as safe as a chromoly cage.
