2) Surface treatment: nitrided, hardening nitrided, polished;
3) The characteristics: wear resistance, good strength, and hardness;
4) Generally crankshaft process: Blank---Quenching and tempering---Shot-blast--Rough machining
----Shot blasting---Heat treatment---Finish machining---Fine grinding---Surface treatment
---Polishing---Finished product;
5) Crankshaft quenching hardening;
6) Identify ways of forged steel and casting iron crankshaft:
a: Appearance: casting iron crankshaft appearance is more rough than forged steel crankshaft;
b: Percussive sound: forged steel crankshaft tapping sound is more ringing & echo is longer;
c: Material chemical analysis;
d: Product weight: casting iron crankshaft is lighter than forged steel crankshaft
(the density of casting iron is 7.2 & 7.8 for forged steel).
