Dab tsi yog qhov txawv ntawm stainless hlau 2507 thiab 2205?
2205 duplex steel, duplex stainless hlau 2205 alloy yog cov hlau tsis sib xyaw ua ke ntawm 21% chromium, 2.5% molybdenum thiab 4.5% nickel nitrogen alloy. Nws muaj lub zog siab, zoo cuam tshuam toughness thiab zoo zuag qhia tag nrho thiab lub zos tiv thaiv kev ntxhov siab corrosion.

2507 yog ib qho ferritic-austenitic (duplex) stainless hlau. Vim yog cov ntsiab lus siab ntawm chromium thiab molybdenum hauv cov hlau no, yog li ntawd, nws muaj kev tiv thaiv zoo heev rau pitting corrosion, crevice corrosion thiab uniform corrosion.
Qhov ob-txoj kev microstructure ua kom cov hlau muaj kev tiv thaiv corrosion siab thiab kev ntxhov siab corrosion cracking kuj, thiab cov neeg kho tshuab lub zog kuj yog siab heev. 2507 stainless hlau yog siv rau hauv kev lag luam roj av thiab roj; offshore Shipotian roj platform (kub exchanger raj, dej kho thiab dej system, hluav taws xob tiv thaiv systems, sprinkler systems, dej stabilization systems; petrochemical khoom; desalination (desalination) cov cuab yeej (thiab high-pressure kav dej nyob rau hauv cov khoom, offshore dej kav); Mechanical thiab structurally rhiab Cheebtsam uas yuav tsum tau muaj zog thiab siab corrosion kuj; }}d\x0a2507 tshuaj muaj pes tsawg leeg ntawm stainless hlau :\x0d\x0aC Tsawg dua lossis sib npaug rau 0. 03, Si Less dua lossis sib npaug rau 0.80, Mn Tsawg dua lossis sib npaug 1.2, Cr:24-26, Ni:6-8, S Less dua lossis sib npaug rau 0.02, P Tsawg dua lossis sib npaug rau 0.035, Mo:3-5, N:0.24-0.32
