Stainless hlau Investment Castings

Ntawm RMC Foundry, feem ntau ntawm covstainless hlau castingsyog tsim los ntawm poob ciabpeev casting txheej txheemvim qhov raug siab. Stainless hlau (SS luv luv) yog cov ntawv luv ntawm stainless thiab acid-resistant steel. Nws yog hu ua stainless hlau uas tiv taus cov tsis muaj zog corrosive media xws li cua, chav, thiab dej. Corrosion steel yog hu ua acid-resistant steel. Peb tuaj yeem nchuav ntau pawg stainless hlau xws li Ferritic Stainless Hlau, Martensitic Stainless Hlau, Austenitic Stainless Hlau, nag lossis daus Hardening Stainless hlau zoo li.Duplex Stainless hlau(DSS). Austenitic stainless hlau, uas yog hais txog cov pab pawg ntawm stainless hlau nrog ib tug austenitic qauv ntawm chav tsev kub, yog feem ntau siv hom stainless rau peev castings. Austenitic stainless hlau yog ib qho ntawm tsib chav kawm ntawm stainless hlau los ntawm crystalline qauv (nrog rau ferritic, martensitic, duplex thiab nag lossis daus hardened). Hauv qee qhov chaw, austentite stainless hlau tseem hu ua 300 series stainless hlau. Thaum cov hlau muaj txog 18% Cr, 8% -25% Ni, thiab txog 0.1% C, nws muaj cov qauv austenite ruaj khov. Austenitic chromium-nickel stainless hlau suav nrog lub npe nrov 18Cr-8Ni steel thiab siab Cr-Ni series steel tsim los ntawm kev ntxiv Cr thiab Ni cov ntsiab lus thiab ntxiv Mo, Cu, Si, Nb, Ti thiab lwm yam ntawm lub hauv paus no. Austenitic stainless hlau yog tsis-sib nqus thiab muaj siab toughness thiab yas, tab sis nws lub zog yog tsawg, thiab nws yog tsis yooj yim sua kom ntxiv dag zog rau nws los ntawm theem transformation. Nws tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias. Yog hais tias cov khoom xws li S, Ca, Se, Te ntxiv, nws muaj cov khoom zoo ntawm machinability.
