8.Quality control:
1. Melting Process: EAF/BOF+LF+VD resulting in ingots
2. Both ends cut by saw
3. Ratio of forging:minimum 3:1
4. Grain size of final product: according to ASTM E112 more than 5,preferred more than 8
5. Ultrasonic test: As per SEP1921 Class C/c or D/d

9.Heat treatment of 42crmo Steel 
Quenched and Tempered (+QT) of EN19 Steel
1. Heat 42crmo steel slowly to 840-875°C;
2. Soak at this temperature then quench in oil;
