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 carbon steel however using a thinner
tubing. My question is, is it really necessary to
post-weld heat treat? I have read in some books that it
would be stupid not to do this because the weld will become
brittle and can crack without heat treatment. However, I
have also read that it is not necessary. Does anyone have
any thoughts or commments on this? I would really
appreciate it.
Thanks,
Sarah Paterson
