Product Description
Carbon Steel Bar/Rod
Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel's hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength,and it is less expensive than other steels.

Carbon steel bar is widely used in many fields as below,
1) can be used in different 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 it can be made into some connecting rods, bolts, wheel gear...
4) this kind of steel is the most common blanks and materials of shaft parts, and the die welding material model is CMC-E45.
