SAE M2 Tool Steel Material Mechanical Properties
Kuoma, Rockwell C (yakadzikama pa621 ° C, yakadzimwa pa1204 ° C): 62 HRC.
Kuoma, Rockwell C (yakadzimwa pa1204 ° C) ): 65 HRC
Yakagadzirwa yeM2 HSS Steel simbi zvinhu
Pakutanga, Pre-Heating kusvika 650-750 ℃， Wobva wapisa kune tembiricha yekunyepedzera. Soak pa 1204 ° C, iva nechokwadi chekupisa zvakakwana. Wobva watanga kuumbwa, tembiricha yekunyepedzera haina kudzika kupfuura 950 ℃. Mushure mekugadzira, tonhorera zvishoma nezvishoma.
Kupisa Kurapa kweSAE M2 Steel
Pakutanga, Zvishoma nezvishoma kupisa kusvika 871 ℃, wozononoka Kutonhorera kusvika 538℃(1000℉) muchoto chekupisa kupisa. Zvadaro kutonhorera mumhepo. Mushure mekuvhara kuomarara HBS: 255 Max.
- M2 chishandiso Simbi Kuomesa
M2 simbi ine yakanyanya kuoma uye inofanirwa kuomeswa nekutonhodza mumhepo yakanyarara. Kushandiswa kwekugezera munyu kana kudzorwa kwevira remhepo kunodiwa kuderedza decarburization, uye kana isipo, kuomeswa kwepakiti mune yakashandiswa pitch coke inokurudzirwa.
- Kudzima kweHSS M2 Steel zvinhu
Kudzima tembiricha / ℃ | choto chekugezera munyu: 1204
Kudzima tembiricha / ℃ | controlled atmosphere chora: 1216
Nguva yekuchengetedza kupisa/min: 5 ~ 15
Kudzima svikiro: Kutonhora kwemafuta
Kuoma: 65 HRc Min
- Kupisa kweHSS M2 Tool Steel
Kupisa tembiricha / ℃ : 540-564
