Metalworking Stainless Steel Material [SUS304] Feature 2

There are various uses.

◎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.
