316 thiab 330 Stainless Hlau: Kub Ntau Qhov Sib Piv thiab Kev Siv
316 thiab 330 Stainless Hlau: Kub Ntau Qhov Sib Piv thiab Kev Siv
316 stainless hlau ua tau zoo nyob rau hauv corrosive ib puag ncig xws li marine / tshuaj ib puag ncig thiab tuaj yeem tiv taus qhov kub thiab txias (txog li 1600℃F ua ntej lub zog degradation). 330 stainless hlau (siab nickel) tau zoo heev - kub lub zog thiab oxidation tsis kam, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob petrochemical, kev kho cua sov siab tshaj 20-10, thiab kub siab tshaj plaws℃F. Ntawm qhov kub siab tshaj qhov twg lub zog ntawm 316 sai sai poob, 330 ua tau zoo dua li 316.
Dab tsi yog qhov txawv ntawm 303 thiab 316 stainless hlau?
316 stainless hlau muaj cov ntsiab lus chromium siab dua me ntsis (16-18%) thiab cov ntsiab lus nickel (10-14%) dua li 303 thiab 304 stainless hlau. Cov yam ntxwv tseem ceeb tshaj plaws ntawm 316 stainless hlau yog qhov sib ntxiv ntawm 2-3% molybdenum, uas ua kom cov hlau zoo dua corrosion.
Dab tsi yog 330 Stainless Hlau?
330 stainless hlau yog austenitic stainless hlau paub txog nws zoo heev - kub lub zog thiab oxidation kuj. Cov hlau no feem ntau yog alloyed nrog chromium (20-25%) thiab nickel (30-35%), nrog me me ntawm manganese, silicon, thiab carbon ntxiv. Cov ntsiab lus siab nickel txhim kho nws cov corrosion kuj thiab ductility, thaum chromium pab txhawb rau nws tag nrho lub zog thiab oxidation kuj.
Hom 316 Stainless Hlau yog dab tsi?
Qhov sib ntxiv ntawm 2% mus rau 3% molybdenum txhim kho corrosion kuj thiab pitting kuj ntawm Hom 316 stainless hlau. Nws yog qhov tsim nyog rau qhov chaw siab tshaj - chloride ib puag ncig, raws li cov qauv pitting thiab crevice corrosion muaj feem ntau tshwm sim hauv cov cheeb tsam no. Nws muaj kev ua tau zoo heev ntawm qhov kub thiab txias, nrog rau kev nkag siab, lub zog tensile zoo, thiab zoo formability thiab weldability. Hom 316 stainless hlau yog dav siv nyob rau hauv siab -chloride ib puag ncig, xws li cov khoom siv tshuaj, thiab hauv kev lag luam shipbuilding, tshwj xeeb tshaj yog rau marine fittings, li qub, thiab twj tso kua mis internals. Nws kuj yog siv dav hauv kev lag luam tshuaj thiab textile; condensers, evaporators, thiab cia tank; thiab cov khoom siv ua zaub mov thiab tshuab. Tsis tas li ntawd, nws yog siv nyob rau hauv lub tshav kub exchangers, kuaj workbenches, khoom siv, thiab cov khoom tswj cov pa phem.

Qhov kub thiab txias
316 Stainless hlau:Ua tau zoo hauv qab li ntawm 1600℃F (870 degree), tab sis lub zog txo qis. Kev kub siab siab -tsis pom zoo siv, tshwj xeeb tshaj yog siab dua qhov kub no. Nws cov ntsiab lus melting yog kwv yees li 2500-2550℃F (1371-1399 degree).
330 Stainless hlau:Zoo heev - qhov kub thiab txias ua haujlwm, tuav lub zog tensile siab hauv qab 1600℃F (870℃). Nws tuaj yeem siv tau ntawm 1900℃F (1038 degree) lossis siab dua thiab nthuav tawm kev nkag siab zoo heev.
Kev kub thiab kev siv ntawm 316 Stainless Hlau
316 stainless hlau feem ntau yog siv nyob rau hauv ib puag ncig corrosive heev, thiab nws cov corrosion kuj tseem zoo dua li ntawm 304 stainless hlau.
Nws qhov kub thiab txias yog me ntsis qis dua li ntawm 304 stainless hlau, nrog lub melting point ntawm 2500℃F mus rau 2550℃F. Yog li ntawd, 316 stainless hlau tsis zoo li 304 stainless hlau rau siab - daim ntawv thov kub.
