- Cov yam ntxwv ntawm Duplex Steel Khoom
Qhov kev ua tau zoo ntawm duplex stainless hlau li qub yog txiav txim siab los ntawm cov khoom ntawm nws cov ntaub ntawv thiab cov yam ntxwv ntawm lub valve nws tus kheej:
Lub npe hu ua "duplex stainless hlau" txhais tau hais tias nyob rau hauv nws cov qauv kev daws teeb meem, ferrite theem thiab austenite theem account rau kwv yees li ib nrab ntawm txhua, thiab feem ntau me me ntawm theem tsis tsawg dua 30%.
Vim lub xub ntiag ntawm ferrite thiab austenite nyob rau hauv nws cov qauv, duplex stainless hlau muaj lub zog ntau dua thiab cov tshuaj chloride kev nyuaj siab corrosion kuj ntawm ferrite stainless hlau thiab cov zoo heev toughness thiab vuam kev ua tau zoo ntawm austenitic stainless hlau. Qhov zoo, nws cov yam ntxwv tseem ceeb ntawm kev ua haujlwm yog raws li hauv qab no:
1. Molybdenum-muaj duplex stainless hlau muaj zoo chloride kev nyuaj siab corrosion kuj nyob rau hauv tsis tshua muaj kev nyuaj siab.
2. Molybdenum-muaj duplex stainless hlau muaj zoo pitting corrosion kuj. Thaum lawv muaj qhov sib npaug pitting tsis kam sib npaug (PRE=Cr%+3.3×Mo%+16×N%), qhov tseem ceeb pitting muaj peev xwm ntawm duplex stainless hlau thiab austenitic stainless hlau zoo ib yam. Lub pitting corrosion kuj ntawm duplex stainless hlau thiab austenitic stainless hlau yog sib npaug rau ANSI 316L. Lub pitting thiab crevice corrosion kuj ntawm high-chromium duplex stainless hlau uas muaj 25% Cr, tshwj xeeb tshaj yog nitrogen, tshaj ANSI 316L.
3. Nws muaj kev tiv thaiv zoo rau corrosion qaug zog thiab hnav thiab corrosion.
4. Zoo meej txhua yam khoom. Nws muaj lub zog siab thiab qaug zog, thiab nws lub zog tawm los yog ob npaug ntawm 18-8 austenitic stainless hlau. Lub elongation nyob rau hauv lub xeev cov tshuaj muaj zog nce mus txog 25%, thiab tus nqi toughness Ak (V-shaped notch) yog siab tshaj 100J.
5. Zoo weldability thiab tsis tshua muaj siab kub tawg. Feem ntau, tsis tas yuav tsum tau preheating ua ntej vuam, thiab tsis muaj kev kho cua sov tom qab vuam. Nws tuaj yeem welded nrog hom sib txawv xws li 18-8 austenitic stainless hlau lossis carbon hlau.
6. Qhov kub ua haujlwm kub ntau ntawm duplex stainless hlau uas muaj chromium tsawg (18% Cr) yog dav dua li ntawm 18-8 austenitic stainless hlau, thiab qhov tsis kam yog me dua.
7. Cov nyhuv hardening ua haujlwm ntau dua li ntawm 18-8 hom austenitic stainless hlau thaum ua haujlwm txias. Thaum lub raj thiab phaj tau deformation nyob rau theem pib, kev ntxhov siab ntau dua yuav tsum tau siv rau deform.
8. Piv nrog rau austenitic stainless hlau, nws muaj ib tug loj thermal conductivity thiab ib tug me me linear expansion coefficient.
9. Nws muaj ntau yam brittleness tendencies ntawm high-chromium ferritic stainless hlau thiab tsis haum rau siv nyob rau hauv ua hauj lwm tej yam kev mob siab tshaj 300 degree.
