I-303 ipleyiti yensimbi engenasici 303 ipleyiti yensimbi engenasici
Inkcazelo emfutshane:
I-Surface finish 303 yintsimbi yokusika yasimahla equlethe isalfure kunye neselenium, ngokulandelelanayo, kwizicelo apho ukusika simahla kufunwa kakhulu kwaye ukugqitywa koMphezulu kuphezulu.I-303 insimbi engenasici iphucula ukusebenza kokusika kunye nokumelana nobushushu obuphezulu bebhondi.Eyona ifanelekileyo kwiileyile ezizenzekelayo, iibholiti kunye namantongomane.
I-303 insimbi engenasici i-austenitic yokusika i-asidi yensimbi engenasici, ukwenzela ukuba kuphuculwe ukusebenza kwentsimbi, inokuthi ifakwe ngaphezu kwe-0.60 Mo kwintsimbi, inokumelana nokuchithwa, imveliso yokusika kakuhle kunye nokuchasana nokutshisa.Ukumelana nokubola.Iimpawu zemishini ye-303 yensimbi engenasici edibeneyo kunye ne-de-stressed, amandla e-tensile yi-515 MPA, isivuno yi-205 MPA, kunye ne-elongation yi-40%.Ubulukhuni obuqhelekileyo be-HRB 90-100, i-HRC 20-25 yensimbi engenasici 303 Qaphela: HRB100 = HRC20
