254SMO Stainless Hlau Yeeb, 1.4547 Stainless Hlau Yeeb, S31254 Stainless Hlau Yeeb, F44 Stainless Hlau Yeeb
Nqe lus piav qhia:
254SMO yog austenitic stainless hlau.Vim nws cov ntsiab lus molybdenum siab, nws muaj kev tiv thaiv zoo heev rau qhov chaw corrosion thiab crevices corrosion.254 SMO stainless hlautau tsim thiab tsim los siv rau hauv halide uas muaj ib puag ncig xws li dej hiav txwv.254SMO kuj tseem muaj kev tiv thaiv corrosion zoo, tshwj xeeb tshaj yog nyob rau hauv halide uas muaj cov kua qaub, zoo dua li cov hlau tsis zoo.Nws C muaj <0.03%, yog li nws hu ua ntshiab austenitic stainless hlau.Super stainless hlau yog ib hom tshwj xeeb stainless hlau, thawj zaug nyob rau hauv cov tshuaj muaj pes tsawg leeg yog txawv los ntawm zoo tib yam stainless hlau, yog ib tug siab alloy stainless hlau uas muaj cov nickel siab, siab chromium, siab molybdenum.Ntawm lawv, 254SMo uas muaj 6% Mo muaj qhov zoo heev hauv zos corrosion kuj, zoo pitting kuj (PI≥40) thiab kev ntxhov siab corrosion kuj nyob rau hauv cov dej hiav txwv, aeration, sib txawv thiab tsis tshua muaj ceev scour.Nws yog cov khoom siv hloov pauv rau Ni-based alloy thiab titanium alloy.Thib ob, nyob rau hauv kev ua tau zoo ntawm kub los yog corrosion kuj, nrog zoo heev kub los yog corrosion kuj, tsis hloov los ntawm 304 stainless hlau.Tsis tas li ntawd, los ntawm kev faib tawm ntawm stainless hlau, tshwj xeeb stainless hlau metallographic qauv yog ib tug ruaj khov austenitic metallographic qauv.
Vim tias qhov tshwj xeeb stainless hlau no yog cov khoom siv siab alloy, yog li hauv cov txheej txheem tsim khoom yog qhov nyuaj heev, feem ntau cov neeg tuaj yeem tso siab rau cov txheej txheem ib txwm ua los ua cov hlau tshwj xeeb no, xws li perfusion, forging, calendering thiab lwm yam.

1. Kev sim ntau yam thiab kev paub dhau los tau pom tias txawm tias qhov kub siab dua me ntsis, 254SMO muaj kev tiv thaiv siab heev rau crevice-corrosion hauv dej hiav txwv, uas tsuas yog ob peb hom stainless hlau muaj.
2. 254SMO's corrosion kuj nyob rau hauv acidic thiab oxidizing halide kev daws teeb meem xws li cov uas yuav tsum tau rau daim ntawv bleaching ntau lawm yog piv rau cov feem ntau resistant nickel-base thiab titanium alloys.
3. Vim tias nws cov ntsiab lus nitrogen siab, 254SMO muaj lub zog ua haujlwm siab dua li lwm yam austenitic stainless hlau.Tsis tas li ntawd, 254SMO muaj ductility siab thiab cuam tshuam lub zog thiab zoo weldability.
4. Lub siab molybdenum cov ntsiab lus ntawm 254SMO ua rau nws muaj ntau dua oxidation tus nqi ntawm annealing, uas ua rau ib tug rougher nto dua li qub stainless hlau tom qab pickling.Tab sis qhov no tsis muaj kev cuam tshuam rau corrosion kuj ntawm cov hlau.
