4.Characteristic of carbon steel plate                       

Nice machanical porpertys and worse  hardenability,so, it is used for machine parts

 

5.Application of carbon steel plate                          

1): Can be used in many fields such as building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electric power, energy, space, building and decoration, etc.

2): Can be made into mould template, mortise pin, column

3): 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...

4): This kind of steel is the most common blanks and materials of shaft parts
