Unfamiliar specs on Transmission Shaft drawing
Unfamiliar specs on Transmission Shaft drawing
(OP)
Folks,
I am looking at a drawing of a transmission shaft, and wonder if anyone can decipher for me:
Material: SCr20
Heat and Surface Treatment: TSH5200G
Carburizing, Quenching and Tempering: Hv720-850
Case Hardening Depth: 0.5G
I can make assumptions about these, but for obvious reasons would prefer it if someone can give me more specific information. The drawing is of Japanese origin, and the specs are completely unfamiliar to me.
Thank you.

"Carburizing, Quenching and Tempering: Hv720-850"
Which is hardness vickers of 720 to 850. (really hard)
As "G" is not any sort of unit of measure I am familar with it may have not photocopied well.... That could be likely as 0.5mm is reasonable for a case depth.
The material spec and heat and surface treatment spec are probably internal to the company producing the b/p.

I love materials science!
