We build construction equip. What experience/recommendations do you have in welding 8740 material? I don't have a thickness yet. Still early in design.

0.55% Ni - 0.5% Cr - 0.25% Mo with about 0.4% C
This material should be weldable using a preheat requirement of about 300 deg F minimum. The thickness of the base metal will dictate specific (possibly higher) preheat requirements. Also, what is the heat treatment condition of this material?

T-1 steel? This is a low alloy steel that is supplied in a quenched and tempered heat treatment for use in structural applications. It is hardenable, and also exhibits good toughness. The weldability of this material is good, as well. However, strict interpass temperature requirements must be followed when welding with T-1 material.
