2205 vs 2507 Duplex Stainless Hlau: Dab tsi yog qhov txawv?
Tso lus
Dab tsi yog 2507 stainless hlau?
2507 stainless hlau yog super duplex stainless hlau paub txog nws lub zog siab thiab tshwj xeeb tiv thaiv corrosion. Nws muaj pes tsawg leeg ntawm kwv yees li 25% chromium, 7% npib tsib xee, thiab 4% molybdenum ua rau nws resistant rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking nyob rau hauv hnyav ib puag ncig, xws li cov uas muaj cov ntsiab lus chloride siab. Cov ntawv thov feem ntau suav nrog kev ua tshuaj lom neeg, cov nroj tsuag desalination, thiab cov khoom siv roj thiab cov khoom siv offshore.
Dab tsi yog cov khoom sib npaug ntawm 2205 stainless hlau?
Qhov sib npaug ncaj nraim rau 2205 stainless hlau yog nws cov qauv tsim raws li lwm cov qauv, xws li UNS S31803 (los yog S32205), DIN 1.4462, thiab ASTM A182 Qib F51. Cov ntaub ntawv no qhia tib yam khoom, thiab qhov sib npaug yog nyob ntawm tus qauv tshwj xeeb raug xa mus rau ib daim ntawv thov.
