Qhov txawv ntawm Duplex 2507 vs 2205 yog dab tsi
Thaum nws los txog rau cov hlau duplex, ntau tus neeg xa mus rau 2507 thiab 2205 hom. Ob lub steels no muaj ntau yam kev siv, xws li kev lag luam tshuaj, roj, thiab roj, marine engineering, thiab lwm yam. Txawm hais tias ob daim ntawv hlau zoo sib xws, muaj qhov sib txawv ntawm lawv cov tshuaj muaj pes tsawg leeg, lub cev muaj zog, corrosion. tsis kam, thiab cov xwm txheej siv tau. Kab lus no yuav tshawb txog cov yam ntxwv ntawm duplex 2507 vs 2205, txheeb xyuas qhov sib txawv ntawm lawv, thiab xaiv cov hlau tsim nyog rau kev siv tswv yim.
Duplex stainless hlau yog hu ua "duplex" vim nws metallographic microstructure muaj ob hom stainless hlau nplej, ferrite, thiab austenite.
Peb feem ntau siv duplex 2507 vs 2205 stainless hlau, yog li dab tsi yog qhov txawv ntawm lawv, thiab qib twg ntawm duplex stainless hlau yuav tsum peb kev lag luam xaiv?
2205 Duplex Steel yog dab tsi?
Duplex stainless hlau 2205 yog cov hlau tsis sib xyaw uas muaj 21% chromium, 2.5% chromium, thiab 4.5% nickel-nitrogen alloy. Nws muaj lub zog siab, zoo cuam tshuam toughness, thiab zoo tag nrho thiab hauv zos kev nyuaj siab corrosion kuj.

Txheej txheem cej luam:
Nyob rau hauv cov nqe lus ntawm kev ntsuam xyuas, lub zog, hardness, thiab corrosion kuj ntawm duplex steel 2507 yog zoo dua 2205, tab sis nws cov nqi yog siab dua. Yog li ntawd, thaum xaiv ob-txoj kev steel, nws yuav tsum tau xaiv raws li qhov tseeb daim ntawv thov. Yog tias xav tau lub zog siab dua thiab tiv thaiv corrosion, thiab cov peev nyiaj txaus, koj tuaj yeem xaiv 2507; yog tias cov peev nyiaj tsawg dua, lossis cov ntawv thov scenario tsis xav tau, koj tuaj yeem xaiv 2205.
