718 ibumbaIcyuma cya pulasitiki 718 cyakozwe na Suwede ASSAB gifite imiterere ya mekanike, ubushobozi bwo gukora, n'ikoranabuhanga ryoroshye ryo gutunganya, bityo gikoreshwa cyane mu nganda zitunganya no gukora ibumba. Byongeye kandi, icyuma cya 718 cyamaze gukomera kugeza ku bukomere bwa 41 ~ 47HRC nyuma yo kuva mu ruganda binyuze mu nzira yihariye yo gukora, ibi bishobora kugabanya uburyo bwo gutunganya ubushyuhe mu mishinga imwe n'imwe no kunoza inyungu z'ubukungu.

Henglei 718 die steel, 3Cr2NiMo yo mu gihugu cyacu ni icyuma cyiza cyane ugereranyije na P20 (3Cr2Mo), kandi ubwiza bwayo bwarushijeho kuba bwiza kugira ngo yuzuze inenge za P20 die steel kandi ihuze n'igihe P20 die steel idashobora kuzuza ibisabwa. Uretse ibyuma bisanzwe byavuzwe haruguru byo mu Bushinwa, ibyuma bigaragara ku isoko ry'ibyuma bya mold mu gihugu cyanjye ni P20+Ni. 718, 718H (ASSAB) yo muri Suwede, PX5\PX4 (Ubuyapani Datong Special Steel), GS-711, GS-738, GS-312, GS-318 (Ubudage Thyssen), M238 ECOPLUS yo muri Otirishiya (Bai Lu Company), CS718 (Ubushinwa Great Wall Special Steel), SWP20 (Shanghai No. 5 Steel Company), n'ibindi, bityo uretse kuba idakoreshwa mu bice bya pulasitiki bya mold bifite ibisabwa byo kurwanya ingese, ubu ni icyuma gisanzwe cya mold ku byuma bya pulasitiki bya mold bikoreshwa cyane. Ubusanzwe byitwa "icyuma cya pulasitiki", kandi ibyuma bishya bigezweho bikunze kubyifashisha nk'ikigereranyo gisanzwe.

Urwego rw'uruganda: ASSAB 718 HB: 290-310

Uko icyuma gitangwa: Icyuma gitangwa mu buryo bwo gupfunyika. Nyuma y'ubwumvikane, gutanga bishobora gukorwa hatabayeho gupfunyika.

Icyuma cya 718 ni icyuma cya pulasitiki cyo muri Suwede cya ASSAB cyakozwe mu buryo bwa kera kandi kidakonjeshwa na aside. Icyuma cyakonjeshejwe mbere, gifite ibikoresho bimwe, isuku nyinshi, imikorere yo gusiga irangi no gushushanya amafoto. Gifite kandi ubushobozi bwo gukomera cyane, imikorere myiza y'amashanyarazi no gutunganya dermatoglyph. Icyuma cyakonjeshejwe mbere gishobora no gukoreshwa mu mwobo w'icyuma kidakonjeshejwe, kandi flange ishobora gukomera kugira ngo yongere ubukana kugeza kuri 52HRC.

Icyuma gifite ubushobozi bwo gukora neza no kudashira, kandi gifite ubukana bumwe. Gifite kandi ubushobozi bwo gusiga neza, ikoranabuhanga ryoroshye ryo gutunganya ibintu n'igiciro kiringaniye, bityo ingano yacyo ni nini.
