Gnee Steel
Dab tsi yog qhov txawv ntawm 420 stainless hlau thiab 316 stainless hlau?
Qhov sib txawv tseem ceeb yog tias 420 stainless hlau yog ib qho nyuaj martensitic stainless hlau, paub txog nws cov hardness siab thiab hnav tsis kam; Thaum 316 stainless hlau yog austenitic stainless hlau, muaj kev tiv thaiv corrosion zoo heev vim nws cov ntsiab lus molybdenum. Qhov no txhais tau hais tias 420 stainless hlau yog qhov zoo tagnrho rau kev txiav cov cuab yeej thiab cov ntawv thov uas xav tau cov npoo ntse, thaum 316 stainless hlau zoo dua rau ib puag ncig nrog cov av noo siab lossis cov tshuaj corrosive.

Dab tsi yog kev siv 420 stainless hlau?
"420 stainless hlau yog dav nrov vim nws qhov siab hardness, zoo heev hnav tsis kam, thiab zoo corrosion kuj, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev txiav cov cuab yeej, cov cuab yeej kho mob, thiab cov khoom lag luam."
420 Stainless hlau yog dab tsi?
420 stainless hlau yog siab - carbon hlau feem ntau siv hauv kev tsim cov hniav thiab cov cuab yeej phais. Nws yog lub npe hu rau nws qhov siab hardness, zoo hnav tsis kam, thiab muaj peev xwm tswj tau nws cov duab ntawm qhov kub thiab txias. Nws yog hlau nplaum thiab belongs rau martensitic stainless hlau qeb. 420 stainless hlau tsis pom zoo rau daim ntawv thov uas yuav tsum tau muaj corrosion kuj.
Dab tsi yog 316 Stainless Hlau?
316 stainless hlau yog feem ntau siv austenitic stainless hlau uas muaj molybdenum, uas txhim kho nws cov corrosion kuj. Nws yog dav siv nyob rau hauv nkoj tsim, tshuaj, khoom noj khoom haus, thiab tshuaj industries . 316 stainless hlau paub txog nws lub zog siab, durability, thiab muaj zog corrosion kuj. Nws tsis yog-sib nqus thiab muaj qhov zoo tshaj plaws weldability.
420 Stainless hlau vs . 316 Stainless hlau: Qhov txawv qhov tseem ceeb
Kev sib xyaw
420 Stainless Hlau: Cov ntsiab lus carbon ntau dua (0.15% - 0.4%), ua rau muaj zog ntxiv tab sis txo cov corrosion kuj.
316 Stainless Hlau: Ntau dua molybdenum (2% -3%) thiab cov ntsiab lus npib tsib xee, muab cov tshuaj tiv thaiv zoo rau chlorides thiab acids.
Lus Cim: Rau CNC machining nroj tsuag, muaj pes tsawg leeg cuam tshuam ncaj qha rau machinability thiab kev ua tau zoo - xaiv cov qib hlau tsis raug tuaj yeem ua rau cov cuab yeej hnav thiab cov nqi tsim khoom.
Hardness
420 Stainless Hlau: Tom qab kev kho cua sov, nws tuaj yeem ncav cuag qhov nyuaj ntawm 50 HRC, ua rau nws yog ib qho nyuaj tshaj plaws stainless hlau muaj.
316 Stainless Hlau: Feem ntau muaj qis hardness (kwv yees li 15-20 HRC), tab sis tseem tuav lub zog zoo thiab tawv.
Tswv yim: Xaiv 420 stainless hlau yog cov npoo ntse los yog hnav heev - cov khoom tiv thaiv yuav tsum tau . 316 stainless hlau yog superior rau cov qauv durability thiab weldability.
Corrosion Resistance
420 Stainless Hlau: Kev tiv thaiv corrosion tsis zoo, tab sis nws yooj yim rau xeb hauv cov av noo, siab - ntsev, lossis tshuaj kho ib puag ncig.
316 Stainless Hlau: Zoo heev tiv thaiv dej hiav txwv, tshuaj, thiab acids.
Tswv yim: 316 stainless hlau yog ib qho kev xaiv nyab xeeb rau CNC- cov khoom siv hauv marine thiab kev kho mob. Tsis txhob siv 420 stainless hlau tshwj tsis yog corrosion tsis yog qhov tseem ceeb.
Abrasion Resistance
420 Stainless Hlau: Siab hardness thiab zoo heev abrasion kuj, haum rau tej cuab yeej, pwm, thiab bearings.
316 Stainless Hlau: Tsawg abrasion kuj, tsis haum rau siab - kev sib txhuam daim ntaub ntawv.
Nco tseg: Siv 316 stainless hlau nyob rau hauv siab - hnav tej yam kev mob yuav ua rau kom cov nqi hloov pauv lub sij hawm.
Oxidation Resistance
420 Stainless Steel: Zoo oxidation kuj qis dua 650 degree, tab sis tsis haum rau ntev -lub sij hawm siab - qhov kub thiab txias ib puag ncig.
316 Stainless Hlau: Zoo oxidation kuj qis dua 870 degree, haum rau siab - qhov kub thiab txias.
Weldability
420 Stainless Hlau: Yooj yim rau vuam; yuav tsum tau preheating thiab post-weld kho cua sov kom tsis txhob tawg.
316 Stainless Hlau: Zoo heev weldability, yog li siv dav hauv kev tsim khoom tsim.
Tswv yim: Yog tias koj qhov CNC machining project xav tau cov khoom siv welded, 316 stainless hlau yog qhov kev xaiv zoo dua.
Thaum tshav kub kub Resistance
420 Stainless Hlau: Ua tau zoo ntawm qhov kub nruab nrab, tab sis corrosion kuj txo qis dua 400 degree.
316 Stainless Hlau: Ua kom zoo corrosion kuj thiab oxidation tsis kam txawm tias kub txog 870 degree.
Machining Performance
420 Stainless Hlau: Machining kev ua tau zoo yog qhov zoo dua nyob rau hauv lub xeev annealed, tab sis kev kho cua sov ua kom tawv tawv thiab cov cuab yeej hnav.
316 Stainless Hlau: Vim nws cov tawv tawv thiab ua haujlwm tawv, nws nyuaj rau tshuab thiab xav tau cov cuab yeej tshwj xeeb.
Tswv yim: Txhawm rau txo cov nqi machining, rau siab - cov haujlwm hardness, xav txog kev siv cov hlau tsis muaj 420 annealed, tab sis yuav tsum ceev faj nrog cov cuab yeej hnav thaum siv cov khoom siv tawv.
