Henglei 718 die steel, 3Cr2NiMo ya dziko lathu ndi kalasi yachitsulo yopangidwa bwino kuchokera ku P20 (3Cr2Mo), ndipo khalidwe lake lasinthidwa kwambiri kuti lidzaze zofooka za P20 kufa zitsulo ndikukwaniritsa nthawi zomwe P20 kufa zitsulo sikungathe kukwaniritsa zofunikira.Kuphatikiza pa magiredi achitsulo omwe tawatchulawa aku China, magiredi achitsulo omwe akuwonekera pamsika wachitsulo cha nkhungu m'dziko langa ndi P20+Ni.Sweden's 718, 718H (ASSAB), PX5\PX4 (Japan Datong Special Steel), GS-711, GS-738, GS-312, GS-318 (Germany Thyssen), Austria's M238 ECOPLUS (Bai Lu Company), CS718 (China Great Wall Special Steel), SWP20 (Shanghai No. 5 Steel Company), etc., kotero kuwonjezera pa kusagwiritsidwa ntchito pazigawo za pulasitiki nkhungu ndi zofunika kukana dzimbiri, panopa ndi mmene zitsulo kalasi kwa anthu ambiri cholinga nkhungu pulasitiki. zitsulo.Nthawi zambiri amatchedwa "pulasitiki nkhungu zitsulo", ndipo zitsulo zatsopano zatsopano zitsulo nthawi zambiri amagwiritsa ntchito ngati kufananitsa.

Dziko lafakitale: ASSAB 718 HB: 290-310

Mkhalidwe wobweretsera: Chitsulocho chimaperekedwa mumkhalidwe wokhazikika.Pambuyo pa mgwirizano, kubereka kungathenso kuchitidwa popanda kuchepetsa.

718 Chitsulo ndi Swedish ASSAB pre-oumitsa galasi asidi-umboni pulasitiki nkhungu chitsulo.Chitsulocho chimawumitsidwa kale, chokhala ndi zida zofananira, ukhondo wapamwamba, ntchito yopukutira komanso kujambula zithunzi.Ilinso ndi kuuma kwambiri, magwiridwe antchito abwino amagetsi komanso magwiridwe antchito a dermatoglyph.Chitsulo choumitsidwa kale chingagwiritsidwenso ntchito pabowo popanda kuzimitsa, ndipo flange imatha kuumitsa moto kuti iwonjezere kuuma mpaka 52HRC.

Chitsulocho chimakhala ndi machinability abwino ndi kuvala kukana, ndi kugawa yunifolomu kuuma.Ilinso ndi ntchito yabwino yopukutira, ukadaulo wosavuta wopanga komanso mtengo wocheperako, kotero kuti mlingo wake ndi waukulu.
