You are correct. No normalizing.Are you Normalizing or Stress Relieving? Normalizing means an austenizing soak and then air cool. Stress Relief is much lower temp to relax residual stresses from welding, and yeah, that IS quick. But the word Normalizing is being used, and that title means specifics as to process.
The top ten most frequently asked questions about TIG welding 4130 Chrome-Moly.
Note the use of heat crayons. You can get a set cheaply from Mcmaster Carr. You can get the hang of it pretty quickly and then won't need them after that.
Also note the lack of requirement for stress relieving. I've seen 5 degrees or more of of torsion get removed from a AB Cub copy fuselage after a guy worked his way down the longeron clusters. You could hear it unwind at one point, and the tone from tapping went way down. There is likely a broad continuum on how much good or bad stress relieving does.
The video that claimed 700F+ degrees was death to 4130 needs no comment. He's simply wrong. The hit on tensile strength to 1100F is minimal. The person implied it made it similar to mild steel, and claimed he had all the test equipment to use, etc, etc, yada, yada. Annealed 4130 is still a huge win over 1018. And every fusion and heat affected zone from welding 4130 should be treated for design purposes as annealed with ER70S rod.
