Kev thov ntawm Stainless Hlau Phaj
Kev xaiv ntawm stainless hlau daim hlau yog ze ze rau kev siv ib puag ncig. Xaiv tus qauv tsim nyog raws li qhov xwm txheej tuaj yeem tsis tsuas yog ua kom muaj kev ua tau zoo tab sis kuj txuag nqi:
304 Stainless Hlau Phaj: Tus nqi ntau tshaj -kev xaiv zoo rau cov xwm txheej niaj hnub. Nws yog qhov tsim nyog rau cov khoom siv hauv tsev (xws li stainless hlau lauj kaub thiab dab dej), kho kom zoo nkauj sab hauv (xws li phab ntsa panels thiab tes tuav), cov kav dej tshiab thiab cov cuab yeej siv tshuab zoo tib yam. Nws tuaj yeem ua tau raws li qhov yooj yim corrosion kuj xav tau ntawm sab hauv tsev thiab qhov chaw qhuav.
304L Stainless Hlau Phaj: Tsom ntsoov rau welded yam ntxwv qhov chaw. Vim nws cov ntsiab lus tsis tshua muaj carbon tsawg, nws tsis txhob cuam tshuam kev sib tsoo tom qab vuam, yog li nws tau siv dav hauv cov khoom siv welded, ntim tshuaj, khoom noj khoom haus thiab siab - cov kav dej kub uas yuav tsum tau vuam.
316 Stainless Hlau Phaj: Rau ib puag ncig hnyav. Nws cov ntsiab lus molybdenum ua rau nws muaj kev tiv thaiv zoo heev rau chloride ion corrosion, yog li nws yog qhov tsim nyog rau cov tsev nyob hauv ntug dej hiav txwv, cov khoom siv dej hiav txwv, cov kav dej tshuaj, cov khoom siv kho mob thiab cov txheej txheem ua zaub mov uas yuav tsum tau muaj siab - zaus tshuaj tua kab mob.
430 Stainless Hlau Phaj: Rau pob nyiaj siv -limited thiab qhuav ib puag ncig. Nws muaj tus nqi qis thiab muaj zog hlau nplaum, tab sis tsis zoo corrosion kuj, yog li nws tsuas yog tsim nyog rau kev kho kom zoo nkauj ib puag ncig qhuav, tsis yog -load- bearing qhov chaw thiab kev txhawb nqa ib ntus.
Cov yam ntxwv cuam tshuam rau tus nqi ntawm Stainless Hlau Phaj
Tus nqi ntawm stainless hlau daim hlau nyob rau hauv kev ua lag luam txawv heev, thiab lub ntsiab influencing yam yog raws li nram no:
Khoom siv: Cov ntsiab lus ntawm cov hlau tseem ceeb xws li npib tsib xee thiab molybdenum ncaj qha cuam tshuam rau tus nqi. Piv txwv li, 316 muaj molybdenum, thiab nws cov nqi yog 20% -30% siab dua li ntawm 304; 304L muaj cov ntsiab lus npib tsib xee ntau dua 304, yog li nws tus nqi siab me ntsis siab dua 304; 430 tsis muaj npib tsib xee, yog li nws yog qhov pheej yig tshaj ntawm plaub tus qauv.
Txheej txheem ntau lawm: Kev ua haujlwm nyuaj thiab cov txheej txheem yuav tsum muaj feem cuam tshuam rau tus nqi. Piv txwv li, daim iav stainless hlau daim hlau xav tau cov txheej txheem polishing ntxiv, thiab lawv cov nqi siab dua li cov hlau txhuam zoo tib yam; 316 yog me ntsis nyuaj rau txheej txheem tshaj 304, uas kuj ua rau tus nqi siab dua.
Specifications thiab Loj: Thickness, dav thiab ntev yuav cuam tshuam tus nqi. Feem ntau, cov phaj tuab dua, ntau dua tus nqi tsev; tshwj xeeb specifications (xws li ntxiv -dav thiab ntxiv- daim hlau ntev) xav tau customized ntau lawm, thiab tus nqi kuj yuav nce raws li.
Nto Zoo: High- zoo stainless hlau daim hlau uas tsis muaj khawb, xuab zeb qhov los yog oxidation me ntsis muaj ntau dua yuav tsum tau thiab tus nqi siab dua cov uas muaj defects.
Key Cov Lus Cim rau Kev Xaiv Cov Hlau Stainless Phaj
Ntxiv rau qhov sib txawv ntawm cov qauv thiab kev nkag siab txog tus nqi, ob lub ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum xaiv kom tsis txhob yuav cov khoom qis dua:
Tshawb xyuas qhov zoo: High- zoo stainless hlau daim hlau muaj ib tug du nto, tsis muaj khawb, xuab zeb qhov los yog oxidation me ntsis. Brushed daim hlau muaj cov kab sib xws, thiab daim iav daim iav muaj qhov cuam tshuam siab. Zam cov khoom uas muaj ntau burrs ntawm cov npoo thiab tsis txaus thickness.
Simple Identification Method: Siv cov hlau nplaum kom paub qhov txawv: 304, 304L thiab 316 feem ntau tsis muaj zog hlau nplaum, thaum 430 muaj zog sib nqus. Koj tseem tuaj yeem siv cov kua dej tshawb pom: 304 thiab 304L tsis hloov xim tom qab poob, thaum qis dua -manganese steel yuav tig liab.
Hauv luv luv, tsis tas yuav dig muag mus nrhiav siab - kawg thaum xaiv cov hlau tsis muaj hlau. Los ntawm kev sib txuas cov kev siv ib puag ncig, kev siv nyiaj txiag thiab kev xav tau, thiab xaiv raws li cov qauv tsis, koj tuaj yeem xaiv cov khoom uas muaj nqi siab thiab kev pabcuam ntev.
