♦zvinhu: Alloy A286( UNS 66286)
♦Saizi: M10-M120
♦Giredhi: AAA Giredhi
♦Isu tinogadzira uye Kugovera a286 Alloy bhaudhi, Screw, Nuts seyepasirese zviyero saizi zvakare inogona kugadzirwa sekutara kwevatengi.
Ikoroy A286iFe-25Ni-15Cr yakavakirwa superalloy yakasimbiswa nekuwedzerwa kwe molybdenum, titanium, aluminium, vanadium uye trace boron.Pasi pe650 ℃, ine simba regoho repamusoro, yakasimba uye inokambaira, yakanaka processing plasticity uye inogutsa welding performance.Iri inokodzera kugadzirwa kweaero-injini inotakura tembiricha yakakwira ichishanda pasi pe650 ℃ kwenguva yakareba, senge turbine disc, press disc, rotor blade uye fastener, etc. zvakadai semahwendefa, forging, ndiro, tsvimbo, waya uye annular parts.
