I've been told this is a heat-treatable steel. Can you tell me which different welding procedures have to be used to weld this material? The most commonly welded heat-treatable steels are 4130, 4340, and 8630. However, any steel prefaced with a 41, 43, or 86 is considered heat-treatable.Welding of HSLA Steels - TWIThe HSLA steels can therefore be welded with lower preheats than would be permitted for conventional carbon-manganese steels, despite their higher strength. The highest risk of cold cracking in these types of steels is therefore in the weld metal, rather than the HAZ.

Why pre-heat before welding? | Westermans Blog
