718 nkhunguChitsulo cha pulasitiki cha 718 chopangidwa ndi Sweden ASSAB chili ndi mphamvu zamakina, makina ogwirira ntchito, komanso ukadaulo wosavuta wopangira zinthu, kotero chimagwiritsidwa ntchito kwambiri m'mafakitale opangira ndi kupanga nkhungu. Kuphatikiza apo, chitsulo cha 718 chouma kale chakhala cholimba mpaka kufika pa 41 ~ 47HRC pambuyo pochoka ku fakitale kudzera mu njira yapadera yopangira, zomwe zingachepetse kulumikizana kwa kutentha m'mapulojekiti ena ndikuwonjezera phindu lazachuma.

Henglei 718 die steel, 3Cr2NiMo ya dziko lathu ndi chitsulo chokwera kwambiri kuchokera ku P20 (3Cr2Mo), ndipo ubwino wake wakwezedwa kwambiri kuti ukwaniritse zofooka za chitsulo chokwera cha P20 ndikukwaniritsa nthawi zomwe chitsulo chokwera cha P20 sichingakwaniritse zofunikira. Kuphatikiza pa chitsulo chokwera cha ku China chomwe chatchulidwa pamwambapa, chitsulo chomwe chikuwoneka pamsika wachitsulo chokwera m'dziko langa ndi P20+Ni. 718, 718H (ASSAB), PX5\PX4 (Japan Datong Special Steel), GS-711, GS-738, GS-312, GS-318 (Germany Thyssen), M238 ECOPLUS (Bai Lu Company), CS718 (China Great Wall Special Steel), SWP20 (Shanghai No. 5 Steel Company), ndi zina zotero, kotero kuwonjezera pa kusagwiritsidwa ntchito pazigawo za pulasitiki zouma zomwe zimafunikira kukana dzimbiri, pakadali pano ndi chitsulo chokwera chaching'ono cha pulasitiki chouma chomwe chimagwiritsidwa ntchito kwambiri. Kawirikawiri imatchedwa "chitsulo cha pulasitiki cha nkhungu", ndipo mitundu yatsopano yachitsulo yomwe yangopangidwa kumene nthawi zambiri imagwiritsa ntchito ngati kufananiza kwachizolowezi.

Mkhalidwe wa fakitale: ASSAB 718 HB: 290-310

Mkhalidwe wa kutumiza: Chitsulocho chimaperekedwa chili mu mkhalidwe wotsekedwa. Pambuyo pa mgwirizano wa onse, kutumiza kungachitikenso popanda kutsekedwa.

Chitsulo cha 718 ndi chitsulo chapulasitiki cholimba chomwe sichimauma ngati galasi chopangidwa ndi pulasitiki cholimba ngati galasi cholimba ngati asidi chopangidwa ndi Sweden ASSAB. Chitsulocho chimauma ngati galasi, chokhala ndi zinthu zofanana, ukhondo wabwino, kupukuta bwino komanso kujambula zithunzi. Chilinso ndi kuuma kwambiri, magwiridwe antchito abwino amagetsi komanso magwiridwe antchito a dermatoglyph. Chitsulo cholimba ngati galasi chingagwiritsidwenso ntchito m'chimbudzi popanda kuzimitsa, ndipo flange imatha kuumitsidwa ndi lawi kuti iwonjezere kuuma mpaka 52HRC.

Chitsulocho chili ndi makina abwino komanso kukana kuwonongeka, komanso kuuma kofanana. Chilinso ndi magwiridwe antchito abwino opukuta, ukadaulo wosavuta wokonza komanso mtengo wake ndi wochepa, kotero mlingo wake ndi waukulu.
