Kev daws teeb meem ntawm stainless hlau yeeb nkab fittings muaj peb txoj haujlwm.
1. Ua kom cov qauv thiab muaj pes tsawg leeg ntawm cov yeeb nkab steel tsis sib xws, tshwj xeeb tshaj yog rau cov khoom siv raw, vim tias qhov kub thiab txias ntawm txhua ntu ntawm cov hlau xaim kub yog qhov sib txawv, ua rau cov qauv tsis sib xws. Thaum qhov kub thiab txias, kev ua haujlwm atomic nce, theem σ dissolves, cov tshuaj muaj pes tsawg leeg ua ib yam, thiab cov qauv ib-theem tsis sib xws tau txais tom qab txias ceev.
2. Tshem tawm kev ua haujlwm nyuaj thiab pab txhawb kev ua haujlwm txias.
stainless hlau yeeb nkab fittings
Los ntawm cov khoom siv kho mob, cov twisted siv lead ua lattice rov qab, cov elongated thiab tawg nplej yog recrystallized, kev ntxhov siab sab hauv raug tshem tawm, lub zog tensile ntawm stainless hlau yeeb nkab fittings yog txo, thiab elongation yog nce.
3. Restore lub inherent corrosion kuj ntawm stainless hlau.
Kev tiv thaiv corrosion ntawm stainless hlau yog txo vim carbide nag lossis daus thiab lattice tsis xws luag los ntawm kev ua haujlwm txias. Tom qab kev daws teeb meem, qhov kev tiv thaiv corrosion ntawm stainless hlau yeeb nkab fittings yog rov qab los rau lub xeev zoo. Rau stainless hlau yeeb nkab fittings, peb lub ntsiab ntawm kev kho kev daws teeb meem yog kub, tuav lub sij hawm thiab txias npaum li cas. Qhov kub thiab txias yog txiav txim siab los ntawm cov tshuaj muaj pes tsawg leeg.
Feem ntau hais lus, rau cov qib uas muaj ntau hom thiab cov ntsiab lus siab ntawm cov ntsiab lus alloying, cov khoom siv tshuaj kub yuav tsum tau nce ntxiv. Tshwj xeeb tshaj yog rau cov hlau nrog cov ntsiab lus siab ntawm manganese, molybdenum, npib tsib xee thiab silicon, cov nyhuv softening tsuas yog ua tiav los ntawm kev nce cov khoom kub thiab ua kom tiav nws. Txawm li cas los xij, thaum cov khoom kub ntawm cov hlau ruaj khov siab siab, cov carbides ntawm cov khoom ruaj khov yog tag nrho yaj hauv austenitic stainless hlau yeeb nkab fittings, thiab yuav los nag hauv daim ntawv ntawm Cr23C6 ntawm cov ciam teb thaum lub sij hawm tom ntej txias txheej txheem, ua rau intergranular. corrosion. Txhawm rau tiv thaiv carbides ntawm cov ntsiab lus ruaj khov los ntawm decomposing rau hauv cov kev daws teeb meem, qhov kev txwv qis dua cov kua dej kub feem ntau yog siv.
