W6Mo5Cr4V2 (M2) ibyuma bishyushye bizunguruka

M2 ni molybdenum ikurikirana ibyuma byihuta cyane, ifite ibyiza bya karbide ntoya inhomogeneity hamwe no gukomera gukomeye. Biroroshye gushyuha, bigomba kugenzura byimazeyo ubushyuhe bwo kuzimya, kurinda cyane kuvura ubushyuhe. Kubera ubukana bwayo no kwambara, bikoreshwa mugukora gukata bigoye gukata ibikoresho byibikoresho. M2 ibyuma byihuta cyane hamwe na karbide yerekanwe ni nini, bityo rero uburyo bukomeye bwo kurinda ubushyuhe bukwiranye no kunyeganyega hamwe no kwikorera imitwaro.

SAE M2 Igikoresho Cyuma Ibikoresho Byumukanishi

Gukomera, Rockwell C (yashyizwe kuri 621 ° C, yazimye kuri 1204 ° C): 62 HRC.

Gukomera, Rockwell C (yazimye kuri 1204 ° C)): 65 HRC

Impimbano ya M2 HSS Ibyuma

Ubwa mbere, Mbere yo gushyushya kugeza 650-750 ℃ ​​， Noneho shyushya ubushyuhe bwahimbwe. Shira kuri 1204 ° C, urebe neza ubushyuhe. Noneho tangira guhimba, ubushyuhe bwimpimbano butari munsi ya 950 ℃. Nyuma yo guhimba, shyira buhoro.

Ubushyuhe bwo kuvura SAE M2 Icyuma

• M2 HSS Icyuma

Ubwa mbere, Buhoro buhoro kugeza 871 ℃ ， hanyuma buhoro buhoro Cool kugeza 538 ℃ (1000 ℉) mumatanura yo kuvura ubushyuhe. Noneho ukonje mu kirere. Nyuma yo gukomera gukomera HBS: 255 Mak.

• M2 igikoresho Gukomera

M2 ibyuma bifite gukomera cyane kandi bigomba gukomera mugukonjesha umwuka utuje. Gukoresha ubwogero bwumunyu cyangwa itanura ryikirere ryifuzwa ni byiza kugabanya decarburisation, kandi niba bidahari, gupakira gukomera muri kokiya yakoreshejwe.
