Stainless Steel Investment Castings

PaRMC Foundry, mazhinji eStainless simbi castingsanogadzirwa newakisi yakarasikainvestment casting processnekuda kwekururama kwepamusoro. Stainless simbi (SS for short) ndiyo chidimbu chesimbi isina tsvina uye acid-resistant simbi. Inonzi Stainless simbi inoshingirira kune zvisina kusimba zvinoodza media zvakaita semhepo, chiutsi, uye mvura. Corrosion simbi inonzi acid-resistant simbi. Tinogona kudurura akawanda madiki-zvikamu simbi isina tsvina seFerritic Stainless Steel, Martensitic Stainless Steel, Austenitic Stainless Simbi, Precipitation Hardening Stainless Simbi pamwe chete.Duplex Stainless Simbi(DSS). Austenitic Stainless simbi, iyo inoreva boka resimbi isina simbi ine austenitic chimiro pakudziya kwekamuri, ndiyo inonyanya kushandiswa mhando yeStainless yekudyara castings. Austenitic Stainless simbi ndeimwe yemakirasi mashanu esimbi isina tsvina nekristaro chimiro (pamwe neferritic, martensitic, duplex uye kunaya kwakaoma). Mune dzimwe nzvimbo, iyo austentite simbi isina tsvina inonziwo 300 yakatevedzana Stainless simbi. Kana simbi ine inenge 18% Cr, 8% -25% Ni, uye inenge 0.1% C, ine yakagadzikana austenite chimiro. Austenitic chromium-nickel simbi isina tsvina inosanganisira yakakurumbira 18Cr-8Ni simbi uye yakakwira Cr-Ni yakatevedzana simbi yakagadziridzwa nekuwedzera Cr uye Ni zvemukati nekuwedzera Mo, Cu, Si, Nb, Ti uye zvimwe zvinhu pahwaro huno. Austenitic Stainless simbi haisi-magnetic uye ine yakakwirira kuoma uye plastiki, asi simba rayo rakaderera, uye hazvibviri kuisimbisa kuburikidza nechikamu chekushandura. Inogona chete kusimbiswa nekushanda kunotonhora. Kana zvinhu zvakaita seS, Ca, Se, Te zvawedzerwa, ine zvakanaka zvimiro zvemachinability.
