2507/s32750/1.4410

2507 yog ib qho super duplex stainless hlau nrog ntau dua cov ntsiab lus alloy, yog li ua rau nws superior rau 2205 hauv corrosion kuj thiab lub zog. Nws muaj kev tiv thaiv zoo heev rau kev hnav, pitting, crevice corrosion thiab chloride stress corrosion cracking. Nyob rau hauv dilute sulfuric acid kis nrog chloride ions, 2507 muaj corrosion kuj zoo dua 904L, uas yog tshwj xeeb uas tsim los tiv thaiv ntshiab sulfuric acid. Vim tias 2507 cov ntsiab lus qis carbon tsawg txo qis qhov kev pheej hmoo ntawm carbide nag lossis daus ntawm cov ciam teb thaum kho cua sov, nws muaj peev xwm tiv taus carbide-txog intergranular corrosion. 2507 tsis haum rau Daim Ntawv Thov uas yuav tsum tau ntev raug rau qhov kub thiab txias siab tshaj 300 ℃ vim muaj kev pheej hmoo ntawm kev txo cov tawv nqaij. Nws lub zog tawm los yog li ob npaug ntawm cov pa austenitic stainless hlau.

 

S32507 Duplex stainless hlau khoom muab los ntawm Beall Kev Lag Luam Group yog cov khoom zoo.
