ASTM A312 Uns S31254 Super Duplex 2507 Stainless Hlau Yeeb Nkab
Qhov zoo ntawm ASTM A312 Uns S31254 Super Duplex 2507 Stainless Hlau Yeeb
- Strong Corrosion Resistance: S31254 thiab 2507 muaj kev tiv thaiv corrosion zoo heev. S31254 yog haum rau acidic, chloride- nplua nuj, los yog seawater ib puag ncig; 2507 yog haum rau siab -chloride thiab siab - ib puag ncig siab.
- Zoo Weldability: S31254 thiab 2507 muab weldability zoo heev. Txawm li cas los xij, S31254 yuav tsum tau saib xyuas kom tsis txhob kub tawg vim nws cov ntsiab lus alloy siab; 2507 yuav tsum tau tom qab-weld kev kho cua sov kom tswj tau cov theem duplex sib npaug.

Cov qhab nia xaiv tau
- UNS S32205 / S31803 (Duplex Stainless Hlau): Cov no muaj kev tiv thaiv zoo corrosion thiab siab zog tab sis pheej yig dua S32750. Haum rau ib puag ncig kev nruj nruj, tshwj xeeb tshaj yog thaum cov nyiaj txiag muaj kev txhawj xeeb.
- Alloy 625 (Nickel Alloy): Paub txog huab cua corrosion thiab kub tsis kam, tshwj xeeb tshaj yog tiv thaiv acidic thiab siab -kub media. Nws yog qhov kev xaiv zoo tshaj plaws, feem ntau siv hauv kev siv tshuaj lom neeg thiab aerospace.
- UNS N08926 (6Mo Alloy / Alloy 1925 hMo): Zoo ib yam li corrosion kuj rau S31254, muab zoo heev pitting thiab crevice kuj, feem ntau siv interchangeably nyob rau hauv seawater daim ntaub ntawv.
- 316L lossis 317L Stainless Hlau: Tsawg dua - cov nqi austenitic qib tsim nyog rau kev dav dav - lub hom phiaj corrosion kuj. Tsis haum rau siab -chloride lossis siab - qhov chaw siab.
- Titanium Qib 2 lossis 5: High corrosion-cov ntaub ntawv tiv taus thiab lub teeb yuag zoo tagnrho rau desalination, marine, lossis aerospace daim ntawv thov uas muaj dej hiav txwv thiab huab cua ib puag ncig.
