It is inexpensive and has high hardening suitability.

【S45C】 ◎Suitable Applications 　・General machine parts ◎Features 　・High hardenability 　・Good machinability 　・Not suitable for welding 　・High-frequency hardening applications 　・Vacuum hardening applications ◎Suitable Processing 　・Milling machining 　・Lathe machining ◎Cost 　・Inexpensive 　・Process reduction possible with polished material S45C is one of the most popular carbon steel materials for machine structural use, with a specific gravity of 7.8. The mechanical properties obtained through heat treatment also improve, expanding its range of applications. Generally, it is used after processes such as hardening and tempering. It is particularly chosen for cases requiring high strength and is commonly processed in grinding applications, including shafts and pins. Its price is not too high, and it is well-distributed as a carbon steel, making it highly versatile. In cases where special properties are not required, S45C is often used as a standard material.

basic information

Differences between S45C and SS400 S45C is a carbon steel for machine structures, while SS400 is referred to as rolled steel for general structures. Both are made of the same iron, but their composition and strength specifications differ. ◎ Hardening High-frequency hardening: HRC 50-60 Vacuum hardening: HRC 45 ◎ Stress Relief The internal stress of S45C material is reduced through annealing treatment to minimize warping during processing. ◎ Weldability When welding, preheating and post-heating are necessary to prevent low-temperature cracking. ◎ Machining Accuracy For round bars, approximately h8 to h10; for flat bars, approximately h12 to h13. ◎ Hardness For raw material, approximately HRC 12. ==========＝＝＝＝＝＝＝＝＝＝＝＝＝ From the related catalog, you can download a summary table of the characteristics of ordinary copper.
