Muaj 3 qhov sib txawv ntawm 304 stainless hlau thiab anustenitic stainless hlau:
Ua ntej, cov yam ntxwv ntawm ob qho sib txawv:
1. Nta ntawm 304 stainless hlau: 304 stainless hlau yog ib qho khoom siv hauv cov hlau tsis muaj zog, nrog lub ntom ntom ntawm stainless hlau, nrog lub ntom ntawm 7.93;, tseem hu ua 18/8 stainless hlau hauv kev lag luam. Kev kub siab tiv thaiv ntawm 800 ℃, muaj cov yam ntxwv ntawm kev ua cov kev ua tau zoo thiab kev nruj.
2. Cov yam ntxwv ntawm Anustenitic Stainless Hlau: Ntxiv rau cov qauv acid, tshuaj pleev thiab lwm yam, thiab lwm yam, nws puas tuaj yeem cuam tshuam txog 0.i thiab lwm yam. cuam tshuam loj. Siab silicon Austenitic stainless hlau muaj zoo corrosion tau zoo rau cov pa roj ntsha nitric.
Thib ob , kev siv ntawm ob qho sib txawv:
1. Kev siv ntawm 304 stainless hlau: Haum rau kev ua zaub mov, khaws thiab tsheb thauj mus los. Muaj cov txheej txheem zoo thiab muaj kev vam meej. Phaj Tshav Kub Kub Pauv, Cov Khoom Siv Hauv Tsev, Khoom Siv Hauv Tsev (Chav Kawm Ntawv 1 thiab 2, Tso Cua Sov, Boilers, Da Dej); Nws pib siv cov khoom siv, cov khoom siv hluav taws xob, ua liaj ua teb, nkoj, khoom noj khoom haus, cov hlau uas muaj peev xwm lees paub.
2. Daim ntawv thov ntawm Austenitic Stainless hlau: dav siv hauv kev lag luam thiab cov rooj tog kom kho kom zoo nkauj thiab kev lag luam kev lag luam. Vim yog cov khoom siv dav dav thiab zoo nkauj ntawm cov hlau tsis muaj roj stainless hlau, nws tau siv dav hauv ntau yam lag luam.
Thib peb, ob pawg sib txawv:
1. Kev faib tawm ntawm 304 stainless hlau: Muaj ntau cov yeeb nkab steel welded yog 304 stainless hlau yeeb nkab rau cov qauv thiab kev lag luam ua kua. Lwm tus yog qhov kev faib tawm ntawm lub teb chaws tus qauv, tus qauv Japanese, tus qauv American thiab lwm yam.
2. Kev faib tawm ntawm AuTenitic Stainless Hlau: Austenitic-ferritic-ferritic-stainless hlau stainless hlau yog ib tug neeg siv roj av uas muaj tus lej rau ib nrab ntawm txhua tus. Xws li cov ncauj lus qis c cov ntsiab lus, cov ntsiab lus crats yog 18% ~ 28%, thiab NI cov ntsiab lus yog 3% ~ 10%. Qee cov hlau ua kuj muaj cov ntsiab lus xws li Mo, Cu, SI, NB, thiab N.
Hom hlau no muaj ob qho tib si Austenitic thiab ferritic stainless hlau tus yam ntxwv. Piv nrog ferrite, nws muaj zog dua thiab tawv, tsis muaj chav kub brittleness, thiab ho txhim kho intergranular tsis kam thiab vuam kev ua tau zoo thiab kev ua haujlwm vuam.
Nyob rau tib lub sijhawm, nws tseem tswj hwm 475 ℃ Brittleness thiab siab thermal conductivity ntawm ferritic stainless hlau, thiab muaj cov yam ntxwv ntawm superplasticity. Piv nrog ustenitic steel hlau, nws muaj lub zog siab thiab ua kom zoo dua kev txhim kho kom muaj kev cuam tshuam corrosion thiab chloride kev ntxhov siab corrosion. Duplex stainless hlau muaj cov pitting zoo heev thiab tseem yog npib npib tsib xee-txuag-txuag stainless hlau.
Xaiv Hangao Tech (Seko Machinery) cov kab hluav taws xob siab stainless hlau welded yeeb nkab ntau lawm kab Austeneritic raj zeb tshuab los tswj kev tsim cov khoom lag luam stainless hlau 304 thiab Austenitic Stainless Hlau Welded Kav tib lub sijhawm. Cov qauv ntoo ib sab thiab cov kabmob cov menyuam tau ua kom zoo los txo cov ncej khiav tawm thiab txhim kho qhov ntsuas cov yeeb nkab ntawm cov yeeb nkab steel. Qhov kev tsim cov tog vuam kuj tseem siv tau cov kev tiv thaiv cov pa roj thaiv kom txo cov oxidation thiab tau txais cov weld zoo dua.
