기능

• It has a uniform microstructure down to the center.
• It has excellent machining characteristics. Machinability ・・・ Best machinability among 30HRC types. Mirror finish ・・・ The structure and hardness are uniform, which is the best among 30HRC types. Shibo-machinability ・・・ To obtain a good shibo-machined surface with little segregation of a material. EDM Workability ・・・ Hardness of EDM layer is low, and polishing removal is easy.
• Excellent weld quality is expected. Welding crack susceptibility ・・・ No weld crack even if preheating and post-heating are omitted. Mirror surface finish and shibo workability ・・・ The segregation of the material is small, and a good shibo working surface can be obtained.
