Dab tsi yog qhov txawv ntawm 201 stainless hlau thiab 304 stainless hlau?
Muaj ntau hom stainless hlau kav. Hais txog kev hais lus, ob cov khoom siv yeeb nkab feem ntau hauv kev kho cov kav dej yog 201 thiab 304 stainless hlau kav. Tej zaum yuav muaj qee cov neeg siv khoom uas tsis paub qhov txawv ntawm ob hom kav dej no. Cov hauv qab no qhia qhov txawv ntawm 304 thiab 201 stainless hlau kav.
1. Cov hom lag luam hauv tsev txawv: 201 lossis 304 hauv Asmeskas tus qauv lossis tus qauv Japanese yog qhov yooj yim thiab meej, tab sis cov hom hauv tsev yog txawv. 304 stainless hlau qib: 06Cr19Ni10 (los yog OCr18Ni9), 201 stainless hlau qib: 1Cr17Mn6Ni5N.
2. Cov khoom sib txawv: 201 thiab 304 stainless hlau kav yog feem ntau siv, tab sis qhov tseeb cov khoom sib txawv. 201 stainless hlau muaj 15% chromium thiab 5% npib tsib xee. 201 stainless hlau yog hloov rau 304 stainless hlau. Standard 304 stainless hlau, uas muaj 18% chromium thiab 9% npib tsib xee.
3. Qhov sib txawv corrosion kuj: Vim yog cov ntsiab lus npib tsib xee sib txawv, qhov corrosion kuj ntawm 201 yog deb tshaj li ntawm 304; cov kua qaub thiab alkali tsis kam ntawm stainless hlau yeeb nkab 201 tsis zoo li 304. 201 muaj cov ntsiab lus ntawm manganese siab, qhov saum npoo yog ci nrog lub teeb tsaus, thiab cov ntsiab lus siab manganese yooj yim rau xeb. 304 muaj ntau cov chromium, muaj qhov matte nto thiab tsis yooj yim rau xeb. Stainless hlau tsis yooj yim rau xeb vim tias chromium-nplua nuj oxide yog tsim nyob rau saum npoo ntawm lub cev steel, uas plays lub luag hauj lwm los tiv thaiv lub cev hlau. 201 khoom yog siab manganese stainless hlau, nws hardness yog siab tshaj 304 stainless hlau, siab carbon thiab tsawg nickel.
4. Cov dej tsis sib haum yog txawv: 201 stainless hlau muaj manganese thiab yuav xeb hauv cov huab cua ntub thiab qab ntsev rau lub sijhawm ntev, thaum 304 stainless hlau yuav tsis xeb yooj yim thiab muaj kev ruaj ntseg zoo, txawm tias nws muab tso rau hauv qhov chaw ntub dej rau ib puag ncig. ntev. Yooj yim rau xeb. Tab sis ntau tus neeg hais tias stainless hlau 304 yog xeb, thiab nws yuav tsis yog 304 kiag li.
5. Kev siv sib txawv: Piv nrog 201 stainless hlau yeeb nkab, 201 thiab 304 stainless hlau kav muaj qhov tsis zoo corrosion kuj. Tsis pom zoo siv nyob rau hauv ib puag ncig ntub dej los yog ntug hiav txwv dej. Nws tuaj yeem siv rau hauv qhov chaw qhuav thiab qee qhov chaw dai kom zoo nkauj uas tsis muaj qhov yuav tsum tau ua, xws li hauv tsev stair handrails, guardrails, stainless hlau ruaj ntseg qhov rooj, stainless hlau teeb pom kev zoo, rooj tog zaum, thiab lwm yam. 304 stainless hlau yeeb nkab muaj corrosion kuj zoo dua thiab siv tau. nyob rau hauv tej qhov chaw humid los yog ntug hiav txwv dej.
6. Cov nqi sib txawv: 304 stainless hlau yeeb nkab muaj peev xwm tiv thaiv xeb, yog li tus nqi kim dua 201. corrosion kuj ntawm 201 yog qhov tsis zoo, yog li tus nqi pheej yig dua, thiab vim tias cov ntsiab lus nickel ntawm 201 yog tsawg. , tus nqi qis dua 304. Tam sim no tus nqi ntawm 304 yog kim dua, feem ntau yog ze rau 20,000 ib tuj, tab sis 304 stainless hlau kav yuav tsawg kawg yog guaranteed siv. Tsis muaj xeb yuav tshwm sim thaum lub sijhawm ua haujlwm.
