Duplex Steel 2205/2507/904L/254SMO Welded Yeeb Nkab

Duplex stainless hlau welded yeeb nkab yog qhov kev xaiv zoo tshaj plaws rau ntau qhov kev lag luam vim nws lub zog siab thiab corrosion kuj, uas ua rau cov khoom muaj zog, zoo heev corrosion kuj, thiab zoo heev toughness. Qee qhov feem ntau siv duplex steels yog 2205, 2507, 904L, thiab 254SMO. Cov qib no zoo heev rau kev kho dej thiab desulfurization ib puag ncig tiv thaiv cov cuab yeej.

• Duplex 2205 yeeb nkab: Qib no yog kev sib xyaw ntawm chromium, molybdenum, thiab nitrogen. Nws yog resistant rau corrosion thiab yog dav siv nyob rau hauv cov tshuaj ua thiab roj thiab roj industries.

   

• Super duplex 2507 yeeb nkab: Qhov no yog qib siab dua ntawm cov hlau duplex uas muaj molybdenum thiab chromium ntau dua. Nws yog heev resistant rau corrosion, yaig, thiab kev nyuaj siab corrosion cracking. Qib no yog siv nyob rau hauv high-temperature thiab high-pressure daim ntaub ntawv.

   

• 904L stainless hlau yeeb nkab: Qib no yog cov pa roj carbon tsawg, siab alloy austenitic stainless hlau. Nws tiv taus corrosion heev, tshwj xeeb tshaj yog nyob rau hauv sulfuric acid thiab chloride tej yam kev mob. Nws yog feem ntau siv nyob rau hauv chemical processing thiab roj thiab roj industries.

254smo yeeb nkab: Qib no muaj cov qib siab molybdenum, chromium, thiab nitrogen, ua rau nws tiv taus corrosion thiab pitting. Nws yog feem ntau siv rau hauv cov ntaub so ntswg thiab ntawv, tshuaj ua haujlwm, thiab roj thiab roj kev lag luam.

Cov specifications rau duplex steel welded kav sib txawv nyob ntawm seb qib. Txawm li cas los xij, cov tshuaj muaj pes tsawg leeg feem ntau zoo sib xws

- Chromium: 21-30 feem pua

- Nickel: 5-8 feem pua

- Molybdenum: 2-5 feem pua

- Nitrogen: .08-.2 feem pua

- Cov pa roj carbon: .03-.06 feem pua

- Hlau: sib npaug

Vuam ntawm Duplex stainless hlau

Duplex stainless hlau muaj zoo weldability. Tag nrho cov txheej txheem vuam txheej txheem tuaj yeem siv tau. Lawv tsis yog yooj yim welded raws li qib austenitic tab sis qis thermal expansion nyob rau hauv duplex qib txo distortion thiab residual stresses tom qab vuam.

Duplex steel welded kav yog siv nyob rau hauv ntau yam kev lag luam, xws li:

- Kev ua tshuaj lom neeg

- Roj thiab roj

- Pulp thiab ntawv

- Kev tsim hluav taws xob

- Kev kho dej

- Kev ua zaub mov

- Tubrog nkoj
