ER 420 tempering / stress relief temperature
(OP)
I've looked and looked but am struggling to find any recommendations for the tempering of a 420 weld metal deposited using a MIG/MAG process. Can anyone help?

They have a technical sheet on 420 stainless steel, including welding. The ER420 stainless steel should be post weld heat treated between 1350 to 1400 deg F for 6 to 8 hours.
