UNS S31803 Duplex Hlau Stainless Hlau Coils
S31803 yog lub koom haum Numbering System (UNS) tsim rau tus thawj duplex stainless hlau. UNS system tau tsim los ntawm ntau pawg kev lag luam hauv xyoo 1970 los txo qhov kev tsis sib haum xeeb los ntawm tib lub alloy hu ua cov khoom sib txawv, thiab rov ua dua. Txhua hlau yog sawv cev los ntawm ib tsab ntawv ua raws li tsib tus lej, qhov twg tsab ntawv qhia cov hlau series, piv txwv li S sawv cev rau stainless hlau.
Siv rau hauv daim ntawv zeb daim ntawv thov uas qis alloy qib tsis muaj kev tiv thaiv corrosion txaus. Raws li 22% chromium cov ntsiab lus, lawv muaj kev sib xyaw ua ke austenitic: ferritic microstructure uas muaj zog ntxiv, tiv thaiv corrosion thiab nqi-zoo.
UNS S31803 (ASTM F51) cov lus qhia tshwj xeeb tau hloov pauv ntau los ntawm UNS S32205 (1.4462, ASTM F60). Qhov no qhia txog lawv lub siab xav ua kom lub zog ntawm cov khoom siv corrosion, pab los ntawm kev txhim kho ntawm AOD steelmaking txheej txheem, uas tso cai rau kev tswj nruj dua ntawm kev sib xyaw. Tsis tas li ntawd, nws tso cai rau qib ntxiv ntawm nitrogen los cuam tshuam es tsis yog tam sim no raws li keeb kwm yav dhau los. Yog li ntawd, qhov ua tau zoo tshaj plaws duplex steel qib nrhiav kom ua kom cov ntsiab lus ntawm chromium (Cr), molybdenum (Mo) thiab nitrogen (N).
