[TheForge] A36 vs 1018

Sat Jun 14 02:21:01 2003

Bob;
Cold rolled is harder cause it is work hardened in the rolling. Once you 
heat it up, 1018, with a lower carbon content should be more cooperative.
Last week I had to toss 3 pieces of worked A36 ( with about 1/2 a day 
each in them) because of cracking...grrr.
