Qhov twg zoo dua SUS304 lossis SUS316?

Rau engineers thiab procurement specialists, xaiv txoj cai stainless hlau yog ib qho tseem ceeb heev. Ntawm cov qib feem ntau yog SUS304 thiab SUS316, ob qho tib si austenitic stainless hlau-tab sis lawv muaj qhov sib txawv tseem ceeb hauv kev tiv thaiv corrosion, nqi, thiab kev siv.

Cov lus qhia no pab cov neeg yuav khoom txiav txim siab, muaj cov ntaub ntawv cov khoom, cov khoom siv kho tshuab, tus nqi, FAQs, thiab kev pom kev lag luam.

 

Dab tsi yogSUS304 Stainless hlau?

SUS304 yog lub npe Japanese rau stainless hlau, sib npaug rau American 304 stainless hlau, thiab raug cais raws li 06Cr19Ni10 hauv Suav teb tus qauv. Nws belongs rau 18-8 austenitic stainless hlau tsev neeg thiab muaj npe rau nws kwv yees li 18% chromium thiab 8% nickel cov ntsiab lus. Vim nws zoo heev corrosion kuj, kub-resistant, zoo mechanical zog, thiab machinability, SUS304 yog dav siv nyob rau hauv kev tsim kho, ua zaub mov, khoom siv kho mob, thiab tshuaj industries.

 

Dab tsi yog SUS316 stainless hlau khoom?

SUS316 yog austenitic stainless hlau nrog ntxiv molybdenum, muab nws superior corrosion kuj piv rau SUS304, tshwj xeeb tshaj yog nyob rau hauv chloride ib puag ncig (xws li dej hiav txwv). Nws muaj cov yas zoo, toughness, txias ua haujlwm, thiab weldability, thiab feem ntau yog siv rau hauv kev tsim cov corrosion-cov khoom siv thiab cov khoom siv, tab sis nws cov nqi kuj siab dua li ntawm 304 stainless hlau.

Qhov twg zoo dua, SUS304 lossis SUS316?

SUS316 muaj ntau molybdenum thiab npib tsib xee dua SUS304, uas txhawb nqa kev tiv thaiv tab sis nce nqi. Nws raug pom zoo rau ib puag ncig uas raug dej hiav txwv, huab cua ntawm ntug dej hiav txwv, lossis hiav txwv cua, qhov twg muaj kev pheej hmoo corrosion siab. Nyob rau hauv ib puag ncig hnyav, cov hlau tsis muaj steel nrog kev ua haujlwm siab dua li SUS316 yuav tsum tau.

 

SUS304 vs SUS316 stianless steel: Corrosion Resistance

SUS316 qhia tau zoo heev corrosion kuj piv rau SUS304, tshwj xeeb tshaj yog thaum raug chloride thiab acidic ib puag ncig. Qhov no yog vim SUS316 muaj kwv yees li 2% molybdenum, txhim kho nws cov kev tiv thaiv rau pitting thiab crevice corrosion, thaum SUS304 tsis muaj molybdenum. Yog li, SUS316 yog qhov tsim nyog rau thaj chaw ntug dej hiav txwv, thaj chaw marine, lossis tuav cov tshuaj corrosive.

SUS304 vs SUS316: Machinability

SUS304 yooj yim dua rau tshuab dua SUS316, muab kwv yees li 45% machinability piv rau SUS316's 36% (xws li 1212 carbon steel). Txawm hais tias ob qho tib si yog austenitic stainless hlau uas ua haujlwm- tawv sai sai thiab ua kom muaj cua sov, SUS316 yog qhov pom tseeb thiab tawv dua vim nws cov ntsiab lus molybdenum.
