S45C/SAE 1045/EN8/C45/CK45 carbon steel bar
1) Common quenched and tempered structural steel
2) Good comprehensive mechanics performance
3) Low hardenability
1) S45C/ 1045/ C45 carbon steel is mainly used to be manufactured moving parts with high strength, such as the impeller of turbomachine, piston of compressor, shaft, gear, rack, worm, etc.
2) Pre-heating before welding and stress relief annealing after welding is very necessary.
