Super Duplex Steel F61 Txheej txheem cej luam
Super Duplex F61, kuj paub los ntawm UNS lub npe S32550, yog siab -kev ua haujlwm stainless hlau paub txog nws qhov tshwj xeeb corrosion tsis kam, siab zog, thiab kav ntev. Cov hlau no yog ib feem ntawm tsev neeg super duplex, uas sib txuas cov yam ntxwv zoo tshaj plaws ntawm ob qho tib si austenitic thiab ferritic stainless hlau. Duplex F61 yog qhov tshwj xeeb tshaj yog zoo- haum rau kev thov cov ntawv thov hauv ib puag ncig hnyav, xws li pom hauv cov roj thiab roj, petrochemical, thiab marine industries.
Duplex F61 Corrosion Resistance
- Pitting thiab Crevice Corrosion: Kev ua haujlwm zoo heev vim muaj chromium, molybdenum, thiab nitrogen cov ntsiab lus.
- Stress Corrosion Cracking: Kev tiv thaiv zoo tshaj plaws rau kev ntxhov siab corrosion tawg hauv chloride- muaj ib puag ncig.
- General Corrosion: Kev ua haujlwm siab rau ob qho tib si acidic thiab alkaline ib puag ncig, ua rau nws tsim nyog rau ntau hom kev lag luam.

Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog PREN ntawm Super Duplex F61?
A: F61 feem ntau muaj aPREN (Pitting Resistance Equivalent Number) of >40. Qhov no ua kom nws nyob ruaj khov rau pitting hauv dej hiav txwv thiab feem ntau cov brine.
Q: Puas yog F61 zoo ib yam li Ferralium 255?
A: Yog.UNS S32550yog lub npe technical,F61yog ASTM A182 forging qib npe, thiabFerralium 255yog tus thawj hom npe.
Q: Cov tooj liab hauv F61 pab tau li cas?
A: 1.5% - 2.5% Copper ntxiv ua rau cov hlau tsis kam tiv thaiv corrosion hauv kev txo cov kua qaub (xws li sulfuric thiab phosphoric acid) thiab txhim kho nws cov hnav tsis kam hauv slurry daim ntaub ntawv.
Q: Dab tsi yog qhov kev kho cua sov rau F61?
A: Nws yuav tsum yogtshuaj annealedntawm qhov kub thiab txias ntawm 1025℃thiab 1125℃(1875℃txog 2050 degree), ua raws li cov dej nrawm nrawm los tiv thaiv kev tsim cov nkig intermetallic theem.
