Application: 

for the C45 steel,

(1)Can be made into mould template, mortise pin, column

(2)This kind of steel have good mechanical property, is widely used in structural parts which may 

     support stress alternation, especially made into some connecting rods, bolts, wheel gear.

(3)This kind of steel is the most common blanks and materials of shaft parts.

Heat treatment:

For the C45 steel, 

1.Quench:1000-1040`C via 600`C and 850`C, preheating oil or wind cooling

2.Temper temperature should be higher than working temperature in order to stabilize the working size of mold

3.Heat up to 650°C of average temperature in order to eliminate the machined stress, 500°c air cooling after electric cooker cooling

4.Tempering, 800-850°c ,slow cooling after diathermia

5. Melting Process of  steel rod
