Dab tsi ua 316 stainless hlau marine qib?
Lo lus "Tubrog nkoj" 316 Stainless hlau feem ntau yog hu ua "marine qib" vim nws txoj kev xaiv corrosion zoo, ua rau nws txoj kev xaiv zoo tshaj plaws rau cov kev siv tubrog nkoj thiab cov ntug dej hiav txwv.
Vim li cas 316 stainless hlau tsim nyog rau cov ntawv thov marine?
Pitting thiab crevice corrosion resistance:
Cov dej ntsev yuav ua rau pitting thiab crevice corrosion, qhov chaw me me lossis cov kab nrib pleb hauv cov hlau. 316 Stainless hlau yog cov nquag tiv thaiv cov hom corrosion, uas yog qhov tseem ceeb rau kev tswj hwm cov qauv kev ntseeg hauv cov tub rog ib puag ncig.
Durability nyob rau hauv huab cua:
Tubrog nkoj ib puag ncig ua rau cov av noo rau cov av noo, ntsev, thiab ultraviolet hluav taws xob. 316 Stainless hlau muaj peev xwm tiv thaiv cov mob no yam tsis muaj kev tsis txaus lossis poob nws lub zog, kom muaj lub neej ntev rau cov khoom siv marine, khoom siv thiab qauv.
Cov Khoom Siv Tsis Muaj Zog:
Hauv nws cov annealed xeev, 316 Stainless hlau tsis yog sib nqus, ua rau nws cov khoom sib nqus yuav yog qhov teeb meem, xws li hauv marine lossis navigation tshuab hluav taws xob.

Qhov twg yog qhov zoo dua, 304 lossis 316 marh6 march marer stainless hlau?
Nyob rau hauv cov av marine ib puag ncig, 316 stainless hlau yog feem ntau nyiam tshaj 304 vim nws qhov zoo dua corrosion tsis kam, tshwj xeeb tshaj yog tawm tsam chlorides. Txawm hais tias ob qib kawm yog Austenitic thiab qhia cov khoom zoo sib xws, 316 muaj molybdenum, uas txhim kho nws lub peev xwm tiv thaiv cov ntsev dej thiab cov mob hnyav.
Puas yog 316 stainless hlau xeb hauv ntsev dej?
316 Cov hlau stainless, ib qho txawv uas suav nrog ib qho ntxiv 2% Molybdenum, qhia ntau ntau rau kev xeb los ntawm cov dej ntsev.
Puas yog 316 stainless hlau kim dua lwm hom?
Yog lawm, vim qhov sib ntxiv ntawm Molybdenum thiab nws superior corrosion tsis kam, 316 stainless hlau kim dua qib kawm xws li 304. Txawm li cas los xij, nws qhov kev ua tau zoo thiab sijhawm ntev hauv tebchaws Marine.
