HEAT TREATMENT
To eliminate the change of hardness from super heat generated in friction welding and to get the proper high strength in coupling, ASAN takes high tensile strength over 100kg * f/mm through quenching & tempering by HRc 30.

Also, after Q/T treatment thread part both pin and box to be induction hardened at HRC 50 hardness.
