Dab tsi yog qhov txawv ntawm 321 stainless hlau thiab 321H stainless hlau?
Dab tsi yog qhov txawv ntawm 321 stainless hlau thiab 321H stainless hlau?
Qhov sib txawv tseem ceeb ntawm 321 thiab 321H stainless hlau nyob hauv lawv cov ntsiab lus carbon: 321 muaj cov ntsiab lus siab tshaj plaws ntawm 0.08%, thaum 321H muaj qhov dav (0.04-0.10%). Qhov no ua rau 321H ua tau zoo dua nyob rau hauv siab - daim ntawv thov kub uas yuav tsum tau nkag siab dua thiab siab - qhov kub thiab txias. Txawm hais tias ob qho tib si yog titanium-stabilized austenitic stainless steels tsim los tiv thaiv intergranular corrosion, 321H tseem xav tau ib coarser grain loj kom ua tau zoo dua qhov kub thiab txias, yog li tso cai rau ob daim ntawv pov thawj hauv ntau qhov xwm txheej.
Cov hlau nplaum puas tuaj yeem nyiam 316 stainless hlau?
Vim nws cov ntsiab lus siab nickel, 316 stainless hlau feem ntau suav hais tias yog "tsawg kawg magnetic" stainless hlau. Txawm li cas los xij, 316 stainless hlau cov khoom lag luam uas tau dhau los ua vuam lossis tshuab ua haujlwm yuav muaj cov hlau nplaum txaus los ua kom pom qhov ntxim nyiam thaum coj los ze rau cov hlau nplaum.

321/321H stainless hlau corrosion kuj
321 Stainless hlau
Kuj:Ob leeg 321 thiab 321H stainless hlau pom zoo heev corrosion kuj. Kev kho titanium stabilization nyob rau hauv 321 stainless hlau ntxiv txhim khu kev tiv thaiv oxidation thiab intergranular corrosion, tshwj xeeb tshaj yog nyob rau hauv siab - kub thiab thaum lub sij hawm vuam.
321H Stainless hlau
Kuj:Txawm hais tias 321H muaj qhov zoo sib xws corrosion tsis kam mus rau 321, nws cov ntsiab lus carbon ntau dua ua rau nws muaj kev cuam tshuam rau intergranular corrosion tsis muaj kev kho cua sov. Post-weld annealing tej zaum yuav tsim nyog los kho qhov corrosion kuj ntawm tshav kub- cuam tshuam cheeb tsam.
Vuam Properties ntawm 321/321H Stainless hlau
321 Stainless hlau
Welding Properties: Ob leeg 321 thiab 321H stainless hlau tuaj yeem yooj yim welded siv cov txheej txheem vuam txheej txheem. Cov ntsiab lus qis dua ntawm 321 stainless hlau txo qhov kev pheej hmoo ntawm kev hnov mob thaum vuam, yog li txo qhov muaj feem cuam tshuam ntawm intergranular corrosion.
321H Stainless hlau
Welding Properties: Txawm hais tias nws cov ntsiab lus carbon ntau dua, 321H tuav cov khoom zoo. Txawm li cas los xij, yuav tsum tau saib xyuas kom tsis txhob muaj cua sov thaum lub sij hawm vuam. Post-weld annealing yog qhov tseem ceeb rau kev ua kom pom kev zoo corrosion, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov tseem ceeb.
