Hauj lwm
M1 yog molybdenum, chromium, vanadium alloy hlau feem ntau hu ua Molybdenum High Speed ​​Tool Steel. Nws yog nyob rau ntawm cov cuab yeej siv dav tshaj plaws hauv kev siv niaj hnub no. Nws zoo ib yam hauv cov khoom rau cov cuab yeej tungsten steels (T series) ntawm qis dua. High-speed Mo steel zoo grindability.

Mos Annealing
Tshav kub rau 820-850oC, txias maj mam hauv qhov cub rau 550oC ces cua. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 262.

Kev Nyuaj Siab Kev Ntseeg
Kev ntxhov siab kom tshem tawm cov kev ntxhov siab yuav tsum tau ua los ntawm cua sov mus rau 600-650oC, tuav rau ib teev ntawm tshav kub, ua raws li cua txias. Qhov kev ua haujlwm no yog ua los txo qis kev sib txawv thaum kho cua sov.

Kev Nyuaj Siab
0 Harden los ntawm qhov kub ntawm 1180-1219oC tom qab cua lossis roj quenching lossis da dej sov ntawm 550oC. Hardness tom qab quenching yog 64-66 HRC.

Tempering
Tempering kub: 530 - 560oC, tsawg kawg yog 2x rau yam tsawg kawg nkaus 63 HRC.

forging
Kub tsim kub: 1100-900oC.

Ua haujlwm txias
Cov hlau no tuaj yeem ua haujlwm txias hauv qhov kev mob annealed.

Kev Siv Siab
M1 yog cais raws li "medium" machinable alloy. Machining yuav tsum ua kom tiav ua ntej hardening kev kho cua sov ua raws li kev sib tsoo tiav. Nws muaj qhov ntsuas ntawm 50% ntawm cov dej hardening (W pawg) cov cuab yeej tsis tshua muaj hlau uas hais txog kev ua haujlwm.

Corrosion Resistance
Qhov no tsis yog corrosion-resistant alloy. Hauv kev siv cov cuab yeej nws feem ntau coated nrog roj kom tsis txhob xeb. Lub teeb zaj duab xis ntawm roj. los yog kev tiv thaiv qhwv, yog qhov tseem ceeb kom nws tsis txhob muaj corrosion.
