303 steel stainless
Imigangatho - ingxubevange 303
ASTM / ASME: uns S30300
EURONORM: FeMi35Cr20Cu4Mo2
Din: 1,4305
Izakhiwo
Yenza ingxubevange 303 non-magnetic, intsimbi engatyiwa austenitic ukuba ayikho hardenable yi unyango bubushushu. Yeyona machining ukuguqulwa sesisa esisiseko-18% chromium / 8% nickel steel stainless. Yenza ingxubevange 303 kwathiwa yenzelwe ukubonisa oluphuculweyo machinabispanty lo gama kugcinwe iipropati elungileyo ngoomatshini umhlwa ukumelana Ngenxa ubukho sulphur kwi ekwakhiweni sentsimbi, ingxubevange 303 yeyona ngokulula machineable steel austenitic stainless; Noko ke, le Ukongeza sulphur wenza ingxubevange 303 kaThixo umhlwa ukuxhathisa ncinane ukuya ngezantsi naleyo ingxubevange 304. spanke amanye amabakala austenitic, ingxubevange 303 ubonisa ubulukhuni kakhulu, nangona nesalfure kuyayehlisa oku spanttle ngokunjalo.
Appspancations
Yenza ingxubevange 303 ngokuqhelekileyo kusetyenziswa appspancations ezifuna izahlulo ukuba kakhulu ngomshini. Eminye imizekelo iquka:
Neenkozo zepistasi, iibholiti
izixhobo Aircraft
Gears
ngezikhonkwane
imigodi
components sokuvula nokucima Electrical
Bushings
nokumelana Resistance
Enokumelana okuhle umoya ngokuzolileyo bako, kodwa ngaphantsi kakhulu kwe ingxubevange 304
Xa sulphur ezongezelelweyo idityaniswa ukuphucula machinabispanty, kunjalo nje sspanghtly ukunciphisa nokumelana
In ezininzi iindawo ezomileyo kunye nowobulali bako, ingxubevange 303 ifaniswa kwezinye aluminium unmodified
Ukuba mabaqhelaniswe emanzi, iindawo zolwandle njengoko kuxhomekeke umhlwa ngokukhawuleza-inaba kunye ifilim irusi ziya kuthanda ukwenza
ezinye yodidi spanke eziqhelekileyo austenitic engatyiwa, oko kuxhomekeke ekubeni umhlwa ngokuhlaziya kwiindawo chloride ngasentla 60 o C
ubushushu Resistance
Ukumelana Good igcwala kwiqondo lobushushu ukuya ku 1700 o F (927 o C)
ukusetyenziswa rhoqo kwiqondo lobushushu ngentla 1400 o F (760 o C) akukho ngokuqhelekileyo kucetyiswa ngenxa khabhayithi imvula leyo kunokukhokelela scaspanng mgaqweni
Akanayo enesiqulatho carbon kangangokuba ke basesichengeni zegazi
