4.Characteristic | |||||||||
Nice machanical porpertys and worse hardenability,so, it is used for machine parts | |||||||||
5.Application of ASTM 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 part. | |||||||||
