Khoom siv 253Ma vs 316 Stainless hlau
253MA yog tsim tshwj xeeb rau cov ntawv thov kub kub nrog kev ua haujlwm zoo tshaj plaws rau oxidation thiab thermal stability, whereas 316 stainless hlau muaj kev tiv thaiv corrosion zoo nyob thoob plaws ntau qhov chaw tab sis yuav tsis ua tau zoo nyob rau hauv cov huab cua kub.
1. Tshuaj muaj pes tsawg leeg:
253MA: Nws yog qhov kub-kub austenitic stainless hlau uas muaj cov qib siab ntawm chromium, nickel, thiab nitrogen, nrog rau kev ntxiv ntawm manganese thiab silicon.
316 Stainless Hlau: Nws yog tus qauv austenitic stainless hlau uas muaj chromium, npib tsib xee, thiab molybdenum, nrog qis qis ntawm carbon piv rauStainless hlau 253MA.
2. Temperature Resistance:
UNS S30815: 253MA Stainless hlau yeeb nkabyog tsim tshwj xeeb rau kev siv kub-kub, muab cov oxidation zoo heev ntawm qhov kub siab txog 1150 degree (2100 degree F).
S31600 Stainless hlau: Thaum316 stainless hlau yeeb nkabmuaj peev xwm tiv taus qhov kub nruab nrab, nws tsis yog tsim tshwj xeeb rau qhov kub thiab txias ib puag ncig zoo li 253MA.
3. Corrosion Resistance:
1.4835 Alloy 253 MA: Nws muaj kev tiv thaiv zoo rau oxidation, sulfidation, thiab carburization hauv ntau qhov chaw, nrog rau cov uas muaj cov sulfur thiab nitrogen ntau. 253MA txawm li cas los xij muaj cov ntsiab lus carbon ntau dua yog li nws muaj kev cuam tshuam rau kev nkag siab zoo.
1.4436 (AISI 316): Nws muab kev tiv thaiv zoo corrosion nyob rau hauv ntau yam atmospheric, tshuaj, thiab marine ib puag ncig, tab sis tej zaum yuav tsis haum rau high-temperature, corrosive heev li 253MA.
4. Mechanical Properties:
Khoom siv 253MA: Nws feem ntau nthuav tawm lub zog siab dua thiab nkag siab zoo piv rau 316 stainless hlau, tshwj xeeb tshaj yog nyob rau qhov kub siab.
316 Stainless Steel: Txawm hais tias nws muaj zog tensile zoo thiab tawm los, 316 stainless hlau yuav tsis ua tau zoo li 253MA nyob rau hauv qhov kub thiab txias.
5. Kev siv:
253MA Stainless: Cov kev siv feem ntau suav nrog cov khoom siv rau hauv qhov cub, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov roj turbines, thiab lwm yam khoom siv kub kub.
316 Stainless Hlau: Siv dav hauv ntau lub lag luam rau cov khoom siv thiab cov khoom siv uas yuav tsum tau muaj kev tiv thaiv corrosion, xws li kev ua tshuaj lom neeg, kev ua zaub mov, tshuaj, thiab kev siv dej hiav txwv.
