How long is a piece of string, if I was making a half shaft I may use better stronger steel than the manufacturers would use as they need to be sensible and save money!
Assuming it's a chomium molybdenum steel, then it could have a tensile strength of somewhere between about 75000 and 85000psi, it will have a hardness probably in the C Rockwell hardness scale.
No idea on Rockwell but it'll be 248-302 on Brinell for EN19 CrMo
That's about C32 in Rockwell or B107 which is a tensile strength of about 150000PSI so they are making them out a pretty good material. Car drive shafts often only about 80,000.
So Ashcroft HD shafts have a greater tensile strength by about 36000psi.
lives up to the HD name then
I'm going Dana axle now and running a GM box so no need to pay Ashcroft prices again![]()
how many points left now
