I-Stainless Steel Investment Castings

Kwa-RMC Foundry, iningi le-insimbi engagqwali castingsakhiqizwa ngengcina elahlekileinqubo yokutshala imalingenxa yokunemba okuphezulu. Insimbi engagqwali (i-SS ngamafuphi) isifinyezo sensimbi engagqwali ne-acid-resistant. Ibizwa ngensimbi engagqwali ekwazi ukumelana nemithombo yemali ebolayo ebuthakathaka njengomoya, isitimu, namanzi. Insimbi yokugqwala ibizwa ngokuthi insimbi engamelana ne-asidi. Singathela izigaba eziningi zensimbi engagqwali njengeFerritic Stainless Steel, Martensitic Stainless Steel, Austenitic Stainless Steel, Precipitation Hardening Stainless Steel kanyeI-Duplex Stainless Steel(DSS). Insimbi engagqwali ye-Austenitic, ebhekisela eqenjini lensimbi engagqwali enesakhiwo se-austenitic ekamelweni lokushisa, iwuhlobo olusetshenziswa kakhulu lwensimbi engagqwali ekutshalweni kwezimali. Insimbi engagqwali ye-Austenitic ingelinye lamakilasi amahlanu ensimbi engagqwali ngesakhiwo sekristalu (kanye ne-ferritic, martensitic, duplex kanye nemvula eqinisiwe). Kwezinye izindawo, i-austentite insimbi engagqwali ibizwa nangokuthi i-300 series stainless steel. Lapho insimbi iqukethe cishe u-18% Cr, 8% -25% Ni, futhi cishe u-0.1% C, inesakhiwo esizinzile se-austenite. Insimbi engagqwali ye-Austenitic chromium-nickel ihlanganisa insimbi edumile engu-18Cr-8Ni kanye nensimbi yochungechunge lwe-Cr-Ni ephezulu ethuthukiswe ngokwengeza okuqukethwe kwe-Cr ne-Ni kanye nokwengeza i-Mo, Cu, Si, Nb, Ti nezinye izici kulesi sisekelo. Insimbi engagqwali ye-Austenitic ayinamagnetic futhi inokuqina okuphezulu kanye nepulasitiki, kodwa amandla ayo aphansi, futhi akunakwenzeka ukuyiqinisa ngokuguqulwa kwesigaba. Ingaqiniswa kuphela ngokusebenza okubandayo. Uma izakhi ezifana no-S, Ca, Se, Te zengezwa, zinezici ezinhle zokusebenziseka.
