W6Mo5Cr4V2 (M2) kub dov steel puag ncig tuav

M2 yog molybdenum series high-speed steel, muaj qhov zoo ntawm cov carbide me me inhomogeneity thiab siab toughness. Yooj yim rau overheating, yuav tsum nruj me ntsis tswj lub quenching cua sov kub, kev tiv thaiv nruj dua rau kev kho cua sov. Vim nws hardness thiab wearability, siv nyob rau hauv kev tsim cov txiav ntau nyuaj rau txiav cov cuab yeej. M2 high-speed steel nrog carbide orientation yog qhov loj dua, yog li kev tiv thaiv nruj dua rau kev kho cua sov yog tsim rau pwm kev co thiab kev poob siab.

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

• M2 HSS Steel Annealing

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.
