S31803 yog duplex stainless hlau thiab SS 316 yog tus qauv austenitic stainless hlau nrog cov tshuaj sib txawv thiab cov khoom.
S31803 yog ib tug duplex stainless hlau, uas txhais tau hais tias nws yog ib tug ua ke ntawm austenitic thiab ferritic stainless hlau. Nws muaj txog 22 feem pua chromium, 5-6 feem pua nickel thiab 3 feem pua molybdenum, nrog rau lwm cov khoom xws li nitrogen thiab tooj liab. Qhov kev sib xyaw ua ke ntawm cov ntsiab lus no muab S31803 muaj zog thiab corrosion kuj piv rau cov qauv austenitic stainless hlau xws li SS316.S31803 cevyog tsim nyog rau cov ntawv thov uas xav tau lub zog siab thiab zoo corrosion kuj nyob rau hauv ib puag ncig hnyav.
SS 316 yog tus qauv austenitic stainless hlau uas muaj kwv yees li 16-18 feem pua chromium, 10-14 feem pua npib tsib xee thiab 2-3 feem pua molybdenum. Paub txog kev ua haujlwm zoo corrosion, mechanical zog thiab kub ua haujlwm.316 stainless hlau yeeb nkabfeem ntau yog siv rau hauv daim ntawv thov uas yuav raug rau qhov kub thiab txias los yog corrosive ib puag ncig.
