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.

◎Suitable Applications 　・General machine parts ◎Features 　・Good machinability 　・Good weldability ◎Suitable Processing 　・Milling processing 　・Lathe processing 　・Welded structures ◎Cost 　・Inexpensive 　・Process reduction possible with polishing material Among SS materials, SS400 is considered the most frequently used material. SS400 refers to materials with a tensile strength of 400–510 N/mm². One characteristic of SS400 is that it contains no carbon, so it does not harden even when heat-treated. Differences between SS400 and S45C: SS400 is classified as general structural rolled steel, while S45C is referred to as carbon steel for machine structures. Both are made of iron, but they differ in composition and strength specifications. ==========＝＝＝＝＝＝＝＝＝＝＝＝＝ 　　　　　　From the related catalog, 　you can download a summary table of the characteristics of ordinary copper. 　Please refer to it for processing guidance if you wish. 　　　　 　　　　Characteristics related to processing【Ordinary Copper】 ===========＝＝＝＝＝＝＝＝＝＝＝＝

SCM435 is a chromium-molybdenum steel with a carbon content of approximately 0.33 to 0.38%. Its yield strength is generally above 485 MPa, and its tensile strength is above 930 MPa. Among chromium-molybdenum steels, it has relatively high mechanical properties. Even slight differences in carbon content can affect mechanical characteristics. ◎ Suitable Applications - General machine parts - Bolts and nuts ◎ Features - High hardenability - Good machinability - Suitable for high-frequency hardening - Suitable for vacuum hardening ◎ Suitable Processing - Milling - Turning - Grinding after hardening It is one of the alloy steels for mechanical structures, commonly referred to as "chromoly" or "chromoly steel." It is an improved version of chromium steel with added molybdenum, offering superior hardenability compared to SCr materials. In addition to excellent resistance to tempering, it has superior mechanical properties and toughness, making it suitable for automotive parts, bolts, and nuts. It is said to maintain strength even at high temperatures around 500°C, and is sometimes used in environments where high temperature and high pressure are expected.

SCM440 is a relatively hard type of chrome-molybdenum steel. It has a yield point of 835 or higher and a hardness of approximately 285 to 352. It is produced from killed steel through rolling and forging. The difficulty of processing the steel depends on the presence of ductility when grinding or polishing. If it is only hard, it can be processed relatively easily. ◎ Suitable Applications - General machine parts - Shafts - Bolts and nuts ◎ Features - High hardenability - Good machinability - High-frequency hardening - Vacuum hardening ◎ Suitable Processing - Milling machining - Lathe machining - Grinding after hardening It is one of the alloy steels for mechanical structures, commonly referred to as "chrome-moly" or "chrome-molybdenum steel."

SUS304 is the most representative stainless steel. It is austenitic, with 18% chromium and 8% nickel as its main components. It is also referred to as "18-8 stainless steel." It has excellent corrosion resistance and good mechanical properties. It is widely used in everything from household items to industrial products. It can harden through cold working, and may exhibit magnetism. ◎ Typical Applications - Food-related - Medical-related - Pharmaceutical-related ◎ Features - High corrosion resistance - Difficult to machine - Good weldability - High stress resistance ◎ Machinability Stainless steel has low thermal conductivity, and the heat generated during cutting (approximately 800 to 1200°C) concentrates at the tool cutting edge. As a result, tool wear progresses rapidly, leading to a short tool life, and it is referred to as a difficult-to-machine material. Additionally, due to concerns about the occurrence of work hardening phenomena, stainless steel is a material that often encounters troubles during machining.

◎Cost Reduction Using SUS304 If welding is not required, switching to SUS303 can reduce processing time. ◎Machinability For reference, the machinability index of S45C is 73, while that of SUS304 is 45, making it difficult to machine. (The smaller the number, the harder the material to cut.) ◎Weldability Welding is possible. However, the corrosion resistance of the welded area and the heat-affected zone will deteriorate. Due to the high thermal expansion rate, distortion and cracking are more likely to occur. ◎Cutting Difficulty Stainless steel has low thermal conductivity, and the heat generated during cutting (approximately 800 to 1200°C) concentrates on the tool cutting edge. As a result, tool wear progresses rapidly, leading to a short tool life, and it is referred to as a difficult-to-cut material. Additionally, there are concerns about the occurrence of work hardening, which can lead to many cutting troubles. ◎Polished Material Accuracy The outer diameter tolerance for centerless round bars is h7.
