... improves the resistance of a metal to SCC. For example, cold-drawn steel wire is more resistant to SCC than oil-tempered wire having equal mechanical properties. Also, cold reduction of low-carbon steel to 50% or less of its original thickness makes it relatively immune to cracking in boiling nitrate...
