Corrosion Kuj
Lub 316LN alloy kuj muaj cov kev tiv thaiv zoo tshaj plaws rau pitting thiab crevice corrosion hauv chloride ib puag ncig, qib ox4l 304 thiab 304l. Nws yog tsim tshwj xeeb rau cov tub rog marine thiab tshuaj lom neeg ib puag ncig. Nws cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau 0.03%) txo qis kev pheej hmoo ntawm carbide nag lossis ua kom muaj kev pheej hmoo ntau dua los cuam tshuam kev xeb.
Dab tsi yog lub hardness ntawm 1.4306 khoom?
Lub brinell hardness ntawm 1.4306 stainless hlau (tseem hu ua x2crni19-11 lossis 304L) feem ntau tsawg dua 215 HB.
Dab tsi yog qhov sib txawv ntawm 1.4306 thiab 1.4307?
1.4306 yog ib qho ntau tshaj plaws ntawm 1.4307. Tshwj xeeb, 1.4306 muaj feem pua siab dua ntawm cov chromium thiab ib qho siab dua ntawm cov neeg tsawg kawg nkaus tsib xee cov ntsiab lus piv rau 1.4307. Piv txwv li, 1.4306 muaj qhov tsis muaj nyiaj tsawg tsawg ntawm 10%, thaum nws muaj tsawg kawg yog 8%. Ob qib tau pom zoo los ntawm cov ntsiab lus muaj roj carbon tsawg, uas txhim kho lawv txoj kev tawm tsam kom muaj kev txhim kho corrosion.
