Txheej txheem cej luam ntawm 321 Stainless Steel Pipe
Raws li ib qho kev hloov kho ntawm SS304, stainless hlau 321 (SS321) yog ib qho hlau stainless hlau austenitic ruaj khov nrog titanium ntxiv tsawg kawg 5 zaug ntawm cov pa roj carbon. Qhov ntxiv titanium txo lossis tiv thaiv qhov kev cuam tshuam ntawm carbide precipitation thaum lub sijhawm vuam thiab hauv kev pabcuam ntawm qhov kub ntawm 425-815 ° C. Nws kuj txhim kho qee qhov khoom ntawm qhov kub siab. SS321 muab kev tiv thaiv zoo rau oxidation thiab corrosion thiab muaj lub zog nkag zoo. Nws yog siv feem ntau hauv cov khoom siv roj refining, cov kav dej siab, radiant super heaters, bellews, thiab cov khoom siv kho cua sov kub siab.

Lub zog qaug zog ntawm 321 Stainless Steel Tube
Hauv cov ntawv thov dynamic, lub zog qaug zog kuj tseem ceeb uas yuav tsum xav txog. Thiab hauv qhov no 321 SS muaj qhov zoo me ntsis dua 304 SS. Kev qaug zog lossis kev ua siab ntev (lub zog hauv kev khoov) ntawm cov hlau tsis xeb austenitic hauv qhov xwm txheej annealed yog li ib nrab ntawm lub zog tensile. Cov kev txwv tensile thiab kev ua siab ntev rau cov alloys no (annealed) tau nthuav tawm hauv lub rooj hauv qab no:
| Cov hlau nplaum | Ib txwm muaj zog Tensile | Kev Txwv Kev Ua Siab Ntev |
| 304L | 68 ksi | 34 ksi |
| 304 | 70 ksi | 35 ksi |
| 321 | 76 ksi | 38 ksi |
Weldability ntawm 321 Stainless Steel Tube
SS321 thiab TP321 muaj qhov weldability zoo heev, tsis tas yuav tsum tau ua ntej cua sov. Cov khoom siv sau yuav tsum muaj cov khoom sib xws tab sis cov ntsiab lus alloy siab dua. Liquation cracking hauv thaj chaw cuam tshuam los ntawm cua sov: cov khoom siv hluav taws xob tsawg. Qhov loj me me. Ferrite ≥ 5%.
Cov hlau uas pom zoo kom siv yog SS 321, 347, thiab 348. Lub electrode yog E347 lossis E308L [qhov kub thiab txias < 370 °C (700 °F)].
Cov ntawv thov ntawm 321 Stainless Steel Tube
Hom 321, 321H thiab TP321 siv tau rau hauv cov chaw uas tsis tuaj yeem kho cov tshuaj tom qab vuam, xws li cov kav dej thiab cov kav dej kub thiab cov tshuab tso pa tawm hauv cov cav sib pauv thiab cov roj turbines nrog qhov kub ntawm 425 txog 870 ° C (800 txog 1600 ° F). Thiab cov kab txhaj roj thiab cov tshuab hydraulic rau cov dav hlau thiab cov tsheb aerospace.
