Dab tsi ua rau 254 SMO "Super"?
254 SMO yog 6% Molybdenum (6Mo) super austenitic stainless hlau. Tsim tshwj xeeb rau kev siv hauv dej hiav txwv thiab lwm yam chloride aggressive -cov kabmob xov xwm, nws muaj kev sib xyaw ua ke ntawm kev ua haujlwm siab, cuam tshuam lub zog, thiab huab cua corrosion tsis kam.
Cov txiaj ntsig tseem ceeb ntawm Kev Ua Haujlwm:
Pitting Resistance:Nrog PREN (Pitting Resistance Equivalent Number) ntawmNtau dua lossis sib npaug rau 42.5, nws deb tshaj cov qauv stainless qib.
Siab zog:Ze liob zaug lub zog tawm losntawm 300-series stainless hlau.
Tus nqi -Efficiency:Muab npib tsib xee- alloy qib kev ua tau zoo ntawm tus nqi qis dua.
Weldability zoo heev:Cov ntsiab lus carbon tsawg ua kom muaj kev tiv thaiv rau intergranular corrosion tom qab vuam.

Cov Lus Nug Nquag: 254 SMO (UNS S31254)
1. Puas yog 254 SMO zoo dua 904L?
Hauv ib puag ncig uas muaj cov tshuaj chloride siab (xws li dej hiav txwv),254 SMO yog superior rau 904L. Thaum 904L zoo heev rau dilute sulfuric acid, 254 SMO muaj ntau dua Molybdenum thiab Nitrogen cov ntsiab lus, muab nws siab dua PREN (42.5+) piv rau 904L (34). Yog tias pitting corrosion yog koj qhov kev txhawj xeeb tseem ceeb, 254 SMO yog qhov kev xaiv zoo dua.
2. Dab tsi yog qhov sib npaug rau 254 SMO?
254 SMO yog lub npe lag luam muaj los ntawm Outokumpu. Nws yog technically cais raws liUNS S31254los yogW. Nr . 1.4547. Hauv kev lag luam, nws kuj nquag hu ua6% Molylos yog6 ib mostainless hlau.
3. Puas yog 254 SMO nyuaj rau vuam?
Txawm tias nws cov complex alloy muaj pes tsawg leeg, 254 SMO muajzoo heev weldability. Nws tuaj yeem txuas tau siv txoj hauv kev zoo li SMAW, GTAW, thiab PAW. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau siv ib qhotshaj - alloyed muab tub lim(xws li Alloy 625) kom ntseeg tau tias cov hlau welding muaj kev tiv thaiv corrosion zoo ib yam li cov khoom siv hauv paus.
4. 254 SMO puas tuaj yeem siv rau hauv siab -cov ntawv thov kub?
Thaum 254 SMO muaj zog txhua yam, nws yog tsim los rauaqueous corrosion kuj. Nws feem ntau pom zoo rau qhov kub thiab txias hauv qab no400℃(750℃F). Saum toj no ntau yam, cov khoom yuav raug txo nyob rau hauv toughness vim nag lossis daus ntawm brittle theem.
5. Vim li cas 254 SMO kim dua 316L?
Tus nqi sib txawv yog tsav los ntawm qhov siabNickel (18%) thiab Molybdenum (6%)cov ntsiab lus. Cov ntsiab lus no yog cov khoom kim heev tab sis tseem ceeb rau cov khoom siv "Super" kev ua tau zoo. Txawm li cas los xij, vim tias 254 SMO siv sijhawm ntev dua hauv cov cheeb tsam hnyav, qhovTus nqi ntawm cov tswv cuab (TCO)feem ntau qis dua 316L, uas yuav tsum tau hloov ntau zaus.
6. HT Pipe ua raws li cov qauv twg rau 254 SMO cov khoom?
Peb tsim thiab muab 254 SMO cov khoom raws li nruj raws li cov qauv thoob ntiaj teb, suav nrog:
