Litšepe tse chitja tsa GCr15 tse chesang

GCr15 ke tšepe e tloaelehileng e sebelisetsoang ho hlahisa libolo le li-ring of bearing. Sehlahisoa se na le litšobotsi tsa sebopeho sa junifomo-lik'hemik'hale, karolo e tlase ea likarolo tse kotsi, bohloeki bo phahameng, carbide e ajoang hantle, boleng bo botle ba holim'a metsi. E boetse e na le litšobotsi tsa boholo bo pharaletseng ba polasetiki, boleng bo tsitsitseng ba phekolo ea mocheso, junifomo, le boima bo phahameng, khanyetso e phahameng, matla a phahameng a ho ama mokhathala. E na le thepa e ntle ea machining ka mor'a spheroidize annealing. GB GCr15 e nang le tšepe ke GB standard Alloy Bearing steel, Ke ea carbon ea boleng bo holimo, alloy chromium, tšepe ea manganese. Thepa ea GB GCr15 ke chromium, manganese alloy steel specification. GCr15 e lekana le AISI 52100, DIN 100Cr6. Lisebelisoa tse ngata li ka nka sebaka sa tse ling.

Phekolo ea mocheso e Amanang

• Ho tšeloa ha tšepe ea GCr15 Alloy

E futhumetse butle ho 790-810 ℃ 'me u lumelle linako tse lekaneng, tlohela tšepe hore e futhumale hantle, Ebe u pholile butle ka sebōping. Mefuta e fapaneng ea mekhoa e tla fumana boima bo fapaneng

• Ho tima le mocheso oa tšepe ea GCr15 Alloy

E futhumetse butle ho 860 ° C, Ebe ho tima ka oli fumana 62 ho 66 HRc thata. Mocheso o phahameng oa mocheso: 650-700 ℃, o pholile moeeng, fumana boima ba 22 ho isa ho 30HRC. Mocheso o tlase oa mocheso: 150-170 ℃, Pholile  ka ari, fumana 61-66HRC thata.

• Mosebetsi o chesang le o batang oa GCr15 Alloy bearing steel

GB GCr15 steel e ka chesa e sebetsa ho 205 ho isa ho 538°C, GCr15 Bearing steel e ka sebetsoa ka mokhoa o batang ho sebelisoa mekhoa e tloaelehileng maemong a seng makae kapa a tloaelehileng.
