Kev sib piv ntawm Stainless Hlau 304 thiab 316L

304 Stainless hlau
304 stainless hlau yog austenitic stainless hlau uas muaj kwv yees li 18% chromium thiab 8% mus rau 10.5% npib tsib xee. Qhov no muaj pes tsawg leeg muab zoo heev corrosion kuj thiab zoo formability.
304 stainless hlau paub txog nws lub zog tensile siab thiab oxidation tsis kam, ua rau nws haum rau ntau yam kev siv. Txawm li cas los xij, nws muaj qhov tsis zoo corrosion kuj nyob rau hauv ib puag ncig chloride piv rau 316 stainless hlau.

 

316L Stainless hlau
316L yog qhov tsawg- carbon variant ntawm 316 stainless hlau. Nws muaj cov ntsiab lus zoo sib xws tab sis nrog cov ntsiab lus siab tshaj plaws ntawm 0.03%.
Cov ntsiab lus qis dua yuav txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum vuam, ua 316L yog qhov kev xaiv zoo tshaj plaws rau kev siv vuam. Nws tuav tib yam corrosion kuj zoo li 316 stainless hlau tab sis ua tau zoo dua nyob rau hauv siab - qhov kub thiab txias.

Kev sib piv ntawm corrosion kuj ntawm 304 thiab 316L stainless hlau

Khoom	304 Stainless hlau	316L Stainless hlau
Corrosion Resistance	Zoo, tiv taus atmospheric corrosion, dej, tsis muaj zog acids, thiab tsis muaj zog alkalis	Piv rau 316, nrog kev ua haujlwm zoo dua vuam thiab corrosion kuj ntawm welds. Resistant rau seawater, chlorides, thiab muaj zog corrosive media zoo li cov organic acids.
Pitting Resistance	Tsawg dua, nws yooj yim rau pitting hauv ib puag ncig chloride	Siab, piv rau 316; molybdenum zoo tiv thaiv pitting.
Crevice Corrosion Resistance	qis	Siab

Corrosion Resistance:

304 stainless hlau nthuav tawm zoo corrosion kuj nyob rau hauv feem ntau ib puag ncig, tab sis yog raug rau chloride corrosion, tshwj xeeb tshaj yog nyob rau hauv marine los yog tshuaj ua ib puag ncig.
316L stainless hlau muaj kev tiv thaiv corrosion zoo tshaj, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj chloride- nplua nuj ib puag ncig xws li marine ib puag ncig, ua rau nws zoo tagnrho rau cov ntug hiav txwv dej thiab tshuaj lom neeg kev lag luam.

 

Tensile zog:
304 stainless hlau: Tensile zog yog kwv yees li 505 MPa.
316L stainless hlau: Zoo ib yam li 316 stainless hlau, tab sis muaj zog me ntsis vim cov ntsiab lus qis dua.

 

Yield zog:
304 stainless hlau: Yield zog yog kwv yees li 215 MPa.
316L stainless hlau: Vim tias cov ntsiab lus qis dua, lub zog tawm los yog qis dua li ntawm 316 stainless hlau.

 

Hardness sib piv ntawm 304 thiab 316L stainless hlau:

Khoom	304 Stainless hlau	316L Stainless hlau
