SAE M2 Tool Steel Material Mechanical Properties
Hardness, Rockwell C (e halefile ho 621 ° C, e tingoe ho 1204 ° C): 62 HRC.
Thata, Rockwell C (e tima ka 1204 ° C) ): 65 HRC
E entsoe ka thepa ea tšepe ea M2 HSS
Qalong, Pre-Heating ho 650-750 ℃，Ebe mocheso ho fihlela mocheso o entsoeng. Soak ka 1204 ° C, etsa bonnete ba hore mocheso o phetse hantle. Ebe o qala ho qhekella, mocheso o entsoeng ha o tlase ho 950 ℃. Ka mor'a ho pheha, pholile butle-butle.
Phekolo ea Mocheso ea SAE M2 Steel
Qalong, futhumatsa butle ho fihla ho 871 ℃, ebe butle-butle Pholisa ho 538℃(1000℉) ka seboping sa mocheso. Ebe o pholile moeeng. Ka mor'a annealing hardness HBS: 255 Max.
- Sesebelisoa sa M2 Ho thatafatsa tšepe
Litšepe tsa M2 tse nang le boima bo phahameng haholo 'me li lokela ho thatafatsoa ka ho pholile moeeng o khutsitseng. Tšebeliso ea sebōpi sa letsoai kapa sebōpi se laoloang se laolehile ho fokotsa decarburization, 'me haeba e le sieo, ho kgothaletswa ho tiisa pakete ka har'a pitch coke e sebelisitsoeng.
