Stellite alloys anonyanya kunzi cobalt akavakirwa neakawedzera eCr, C, W, uye/kana Mo. Iwo anoshingirira kune cavitation, corrosion, erosion, abrasion, uye galling.Iwo ezasi kabhoni allov anowanzo kukurudzirwa kune cavitation, kutsvedza kupfeka, kana ine mwero gallina.Iwo epamusoro kabhoni alloys anowanzo kusarudzirwa abrasion, galling yakanyanya, kana low-angle erosion.
Iwo maStellite alloys anochengeta zvivakwa zvawo pakupisa kwakanyanya uko ivo zvakare vane yakanakisa oxidation kuramba.Iwo anowanzo shandiswa mutembiricha renji 315-600° C (600-1112 F).Ivo vanogona kupedzwa kusvika kune yakasarudzika mazinga ekupedzisa kwepasi neiyo yakaderera coefficient yekukwesha kuti ipe yakanaka yekutsvedza kupfeka.
Alloy | Composition | HRC yakaoma | Kunyungudika ℃ | Typical Applications |
Stellite 6 | C: 1 Kr:27 W:5 Co:Bal | 43 | 1280-1390 | Tough erosion-resistant alloy inoshandiswa zvakanyanya kuita zvakanaka kutenderera kwese kuita.Kuita kushoma kutsemuka kupfuura Stellite" 12 n yakawanda layer, asi yakanyanya kupfeka inopokana kupfuura Stellite" 21 ir abrasion uye simbi kune simbi mamiriro.Mamiriro ezvinhu akanaka.Good impact resistance.Zvigaro zvevhavha nemasuwo: ump shafts uye mabhengi.erosion shields uye rollina vakaroorana.Kazhinji inoshandiswa self-mated.Inogona kushandurwa ne carbide tooling.Inowanikwawo setsvimbo, electrode uye waya. |
Stellite 6B | C: 1Mak:30 W:4.5 Co: Bal | 45 | 1280-1390 | |
Stellite12 | C:1.8 Kr: 30 W:9 VaKo :Bа | 47 | 1280-1315 | Properties pakati peaya eStellite "1 uye Stellite" 6.More abrasion resistance pane Stellite" 6, asi stil good impact resistance. Inoshandiswa zvakanyanya sekucheka kumucheto mumaindasitiri emucheka, matanda uye mapurasitiki uye maberinas.Inowanikwawo setsvimbo, electrode uye waya . |
Kazhinji shandisa cemented carbide maturusi kugadzirisa 6B, uye kurongeka kwepamusoro ndeye 200-300RMS.Alloy tools inoda kushandisa 5° (0.9rad.) negative rake angle uye 30° (0.52Rad) kana 45° (0.79rad) lead angle.6B alloy haina kukodzera kupeta-kumhanya uye kushandiswa kweEDM kunoshandiswa.Kuti uvandudze kupera kwepamusoro, kukuya kunogona kushandiswa kuwana yakakwira chaiyo.Haikwanise kudzimwa mushure mekukuya yakaoma, kana zvisina kudaro ichakanganisa chitarisiko
Stellite inogona kushandiswa kugadzira mavharuvhu mavharuvhu, pombi plunger, steam injini anti-corrosion mavhavha, tembiricha yakakwira, mavharuvhu madzinde, midziyo yekugadzira chikafu, mavharuvhu etsono, inopisa extrusion molds, kugadzira mabrasives, nezvimwe.
