1045 Steel Coil Application
1045 steel is widely used for the industry application that required higher strength and wear resistance than low-carbon steel. And the typical applications are gears, shafts, bolts, forged connecting rods, rolls, crankshafts, sockets, heavy-duty mandrels and so on.
C45 Steel Coil Characteristics
1.It is carbon steel and has great weldability and machinability.
2.After normalized and hot rolled, it will get high strength and impact properties.
3.It has low hardenability and critical hardenability diameter is 12-17mm in the water. And there has a tendency to crack when water quenching.
4.The hydrogen welding and argon arc welding is good for it, but the gas welding is not. It is required to preheat before the welding, and stress relief annealing should be performed after welding.
5. Good cold and hot workability, good mechanical properties

1045 Steel Process Notes
1.The hardness is between HRC20~HRC30 after quenching and tempering.
2.After quenching, the hardness is between HRC55~58 and the limit value up to HRC62.
3.In order to make the steel performance stable, it should be processed and placed for 15-20 days before the use. The highest hardness for practical application is HRC55 (high-frequency quenching HRC58).
4.It is a high-quality carbon structural steel with low hardness. It is easy to cut, and it is used to make molds, guideposts, tips, templates and etc.
5.Do not use the heat treatment process of carburized and quenched.
