Welding Domex 100XF and 700 MC

[Metaluser5]

Does anyone have a code or details/procedure for a stress relief treatment for welds using DOMEX 100XF or 700MC steel? Many HSLA steel weldments use the 1000F stress relief treatment but I can not much info for these two alloys. It might be that it is not needed since both alloys are low carbon. [ Using 100ksi MIG wire]. Thanks

Unlikely to need stress relief:

These materials require no post weld heat treatment (stress relief) and heat input is critical to avoid loss of toughness.
