Conclusions
-
1.
Steel 60KhFA, distinguished from ordnary structural steels by its higher carbon concentration, is suitable for crankshafts in truck engines.
-
2.
The heat treatment developed is recommended for crankshafts where the surface hardness of the main journals must be the same as that of roller bearings.
