Product Description

50 steel is a medium-carbon high-strength carbon structural steel, corresponding to Japanese grades S50C/S53C and German grades 1.1213/CF53. The standard it follows is GB/T 711-2017. It has excellent machinability and uniform microstructure, and is suitable for surface hardening treatments such as high-frequency quenching and flame quenching. This material can improve cutting performance after quenching or normalizing. It has low hardenability and the surface hardness can reach 45-52 HRC after quenching. It is mainly used to manufacture mechanical parts and tools with high wear resistance and capable of withstanding dynamic loads. The surface hardness of the unquenched material is 28-32 HRC.

Heat treatment specifications: quenching at 830 ℃± 20 ℃, oil cooling; Tempering at 540 ℃± 50 ℃ (± 30 ℃ if necessary).

Reference corresponding steel grades: German DIN Standard Material Number 1.1213, German DIN Standard Steel Number Cf53, Chinese GB Standard Steel Number 50, British BS Standard Steel Number 060A52, French AFNOR Standard Steel Number XC48TS, French NF Standard Steel Number C50, Italian UNI Standard Steel Number C53, Belgian NBN Standard Steel Number C53, Swedish SS Standard Steel Number 1674, American AISI/SAE/ASTM Standard Steel Number 1050, Japanese JIS Standard Steel Number S50C/S53C, International Organization for Standardization ISO Standard Steel Number C50E4.
