Qib 316 Stainless Hlau - Cov khoom siv, kev ua haujlwm & kev siv

316 Stainless hlau

Stainless hlau 316 muaj ib qho ntxiv ntawm molybdenum uas ua rau nws txhim kho corrosion kuj. Qhov no tshwj xeeb tshaj yog rau pitting thiab crevice corrosion nyob rau hauv ib puag ncig chloride.

316L Stainless hlau

316L, qhov qis carbon version ntawm Stainless hlau 316, yog kev tiv thaiv rau grain ciam carbide nag lossis daus (sensitisation). Qhov no ua rau nws haum rau siv nyob rau hauv hnyav ntsuas (tshaj li 6 hli) welded Cheebtsam.

316Ti thiab 316H Stainless Hlau

Rau kev siv kub siab, cov pa roj carbon ntau ntau, 316H stainless hlau thiab qib 316Ti stainless hlau yuav tsum tau ua haujlwm.

Lub austenitic qauv ntawm Stainless hlau 316 muab zoo heev toughness, txawm nyob rau hauv cryogenic kub.

ASTM A240/A240M

Cov ntaub ntawv khoom vaj khoom tsev tau muab rau hauv daim ntawv no yog ib qho tseem ceeb rau cov khoom lag luam bar thiab ntu uas tau them los ntawm EN 10088-3: 2005. ASTM, EN lossis lwm yam qauv yuav them rau txhua yam khoom muag. Nws yog qhov tsim nyog los cia siab tias cov kev qhia tshwj xeeb hauv cov qauv no yuav zoo sib xws tab sis tsis tas yuav zoo ib yam rau cov uas tau muab rau hauv cov ntaub ntawv no.

Stainless hlau qib 316Ti muaj me me ntawm titanium. Titanium cov ntsiab lus feem ntau tsuas yog nyob ib ncig ntawm 0.5%. Lub titanium atoms stabilize tus qauv ntawm 316 ntawm qhov kub thiab txias tshaj 800 ° C. Qhov no tiv thaiv carbide nag lossis daus ntawm cov ciam teb nplej thiab tiv thaiv cov hlau los ntawm corrosion. Qhov txiaj ntsig tseem ceeb ntawm 316Ti yog tias nws tuaj yeem tuav tau ntawm qhov kub siab dua rau lub sijhawm ntev dua yam tsis muaj qhov tshwm sim (teev los nag) tshwm sim . 316Ti khaws cov khoom siv lub cev thiab cov cuab yeej cuab tam zoo ib yam li cov qauv qib 316.
