Cov qhab nia xaiv tau
- Rau cov kev pabcuam uas muaj cov tshuaj chloride tsawg thiab kev ua haujlwm nruab nrab (feem ntau<80°C), Grade 2205 (UNS S31803/S32205) is a suitable choice; it offers lower costs and superior weldability compared to Grade 2507.
- Nyob rau hauv ib puag ncig me me corrosive-tshwj xeeb yog cov uas tsis muaj cov tshuaj chloride ions lossis tsuas yog muaj cov lej xwb- tus nqi ntau tshaj - kev xaiv zoo, 316L stainless hlau, yuav raug txiav txim siab.
- Rau qhov xwm txheej huab cua uas muaj qhov tshwj xeeb ntawm qhov kub thiab txias siab, 254SMO yog qhov kev xaiv siv tau; thaum nws boasts zoo heev corrosion kuj, nws cov neeg kho tshuab lub zog yog ho qis dua cov super duplex stainless hlau, thiab nws cov nqi ntau dua.
