SAE M2 cuab yeej hlau khoom Mechanical Properties
Hardness, Rockwell C (tempered ntawm 621 ° C, quenched ntawm 1204 ° C): 62 HRC.
Hardness, Rockwell C (quenched ntawm 1204 ° C): 65 HRC
Forged ntawm M2 HSS Steel hlau khoom
Thaum xub thawj, Pre-Heating rau 650-750 ℃, Tom qab ntawd kub rau forged kub. Soak ntawm 1204 ° C, xyuas kom sov kom huv si. Tom qab ntawd pib forged, qhov forged kub tsis qis dua 950 ℃. Tom qab forging, txias maj mam.
Kev kho cua sov ntawm SAE M2 Steel
Thaum xub thawj, Maj mam cua sov mus rau 871 ℃, ces maj mam txias rau 538 ℃ (1000 ℉) hauv qhov cub kho cua sov. Tom qab ntawd txias hauv huab cua. Tom qab annealing hardness HBS: 255 Max.
- M2 cuab yeej Steel Hardening
M2 steel muaj hardenability heev thiab yuav tsum tau hardened los ntawm txias nyob rau hauv tseem huab cua. Kev siv cov ntsev da dej los yog lub qhov cub hluav taws xob tswj tau yog qhov tsim nyog kom txo qis decarburization, thiab yog tias tsis muaj, pob tawv tawv hauv cov suab coke tau pom zoo.
- Quenching ntawm HSS M2 Steel cov khoom
Quenching kub / ℃ | ntsev da dej rauv: 1204
Quenching kub / ℃ | Tswj cua sov cua sov: 1216
Lub sijhawm txuag hluav taws xob / min: 5 ~ 15
quenching nruab nrab: roj txias
Hardness: 65 HRC Min
- Tempering ntawm HSS M2 Tool Steel
Tempering kub / ℃: 540-564
Tom qab tempering hardness HRC los yog siab dua: 65 Min
