- Hey guys, I know some teams last year used chrome-moly steel for their roll cage. I understand that we can save a lot of weight using this type of steel as it can maintain the same strength as plain

- There's really not a huge advantage to using 4130 in that most of the tubing sizes are mandated by the rules. Additionally as you stated, the weld causes 4130 to lose it's strength around the weld an

- There actually isn't any weight savings compared to 1020 steel for the frame. 1020 and 4130 still have the same modulus of elasticity so for the same "I" value the bending stiffness is still the same

- Our team also did a bunch of research as to whether or not 4130 gets brittle in the HAZ. I did a few "tests" on MIG welded .049" wall chromoly tubing, in which i welded some sample pieces at about 70

- Here's the deal with the steel. Chro-Moly tube has a better strength to weight ratio than most mild steel alloys. Where there really is a gain over mild steel, is in what we call the "dimple factor,"
