Yes, Exactly what EdStainless said. Without seeing the axle or break point I would assume it broke because it was a heat treated part that became brittle. I would only recommend welding on anything in its annealed state. Then Heat treating afterwards. If you do have to weld on it use the...
Right, After doing research I noticed the max achievable surface hardness was much higher on the 135 material but the max achievable case depth was more on the 4340. With the 4340 material I have the shafts made from right now that I am looking to get heat treated. What kind of strength...
dbooker630, Carbo-Austempering is a quite different process then the normal carburizing you see done today. I have done quite a bit of reading on this process myself and also read some literature using this process with 4340. I just wanted insight from someone else whom may of had some real...
dbooker630, Thank you for your response. I have actually contacted a lot of companies in U.S about induction hardening this shaft. Once I send them the drawing of the shaft they tell me that the shaft has too many steps in it and it would cost a fortune for me for a company to have to supply a...
The shear stress was taken from the rear most part of the shaft which in this case is the longest/ smallest cross section at 1.375" diameter with the spline major diameter being the same size (estimate). In this world racing it is not uncommon to see 10k ft lbs of force on the drive axles and...
Hello All,
I am new here and this is my first time posting a thread. I would like some feedback from either expert advise or real world experiences. I have Machined a few aftermarket performance transmission main shafts for a transmission that did not see much attention in aftermarket upgrade...
