Dab tsi yog qhov txawv ntawm 446 stainless hlau thiab 316 stainless hlau?
Dab tsi yog qhov txawv ntawm 446 stainless hlau thiab 316 stainless hlau?
Qhov sib txawv tseem ceeb nyob hauv lawv cov khoom: 446 stainless hlau yog siab - kub, tshav kub- tiv taus ferritic stainless hlau nrog oxidation zoo heev thiab scaling kuj; thaum 316 stainless hlau yog ib qho qis- kub resistant austenitic stainless hlau, muaj koob npe rau nws superior corrosion kuj nyob rau hauv ntau yam puag ncig. 446 stainless hlau yog sib nqus thiab haum rau siab - kub daim ntaub ntawv; 316 stainless hlau tsis yog -sib nqus, muaj cov khoom ua haujlwm zoo dua, thiab yog qhov tsim nyog rau corrosive ib puag ncig xws li marine lossis tshuaj nroj tsuag.
Dab tsi yog 446 stainless hlau?
446 yog ferritic stainless hlau alloy, smelted siv AOD (Alternating Oxidation) txheej txheem. Cov alloy no tsis yog hardenable, tab sis nws pom zoo heev corrosion kuj ntawm qhov kub siab heev thiab muaj cov khoom zoo txhua yam. Vim nws cov ntsiab lus chromium siab (kwv yees li 25 wt%), qib no muaj qhov tsis zoo ductility.
446 Stainless hlau
446 stainless hlau feem ntau yog tsim los ntawm hlau, chromium, thiab carbon. Nws kuj tseem muaj cov lej ntawm nickel, manganese, silicon, phosphorus, sulfur, titanium, thiab lwm yam. Cov ntsiab lus chromium siab muab 446 qib stainless hlau zoo heev corrosion kuj, ua kom nws tiv thaiv corrosion los ntawm oxidizing acids xws li nitric acid thiab sulfuric acid.
