Txheej txheem cej luam ntawm 321 Stainless Hlau Yeeb Nkab
Raws li kev hloov kho ntawm SS304, stainless hlau 321 (SS321) yog ib qho ruaj khov austenitic stainless hlau nrog titanium ntxiv ntawm tsawg kawg 5 npaug ntawm cov ntsiab lus carbon. Qhov sib ntxiv ntawm titanium txo lossis tiv thaiv qhov kev xav ntawm carbide nag lossis daus thaum vuam thiab hauv cov kev pabcuam ntawm qhov kub ntawm 425-815 ° C. Nws kuj tseem txhim kho qee qhov khoom ntawm qhov kub siab. SS321 muab kev tiv thaiv zoo rau oxidation thiab corrosion thiab muaj zog nkag tau zoo. Nws yog siv feem ntau hauv cov khoom siv roj refinery, cov kav dej siab, radiant super heaters, bellews, thiab high-temperature heat treatment equipment.

Fatigue Strength ntawm 321 Stainless Hlau Tube
Hauv kev siv dynamic, qaug zog lub zog kuj tseem ceeb los xav txog. Thiab nyob rau hauv no hwm 321 SS muaj ib tug me ntsis zoo dua 304 SS. Kev qaug zog lossis kev txwv tsis pub muaj zog (lub zog hauv kev khoov) ntawm austenitic stainless hlau nyob rau hauv cov mob annealed yog hais txog ib nrab ntawm lub zog tensile.Tej tensile thiab endurance txwv rau cov alloys (annealed) muaj nyob rau hauv cov lus hauv qab no:
| Alloy | Hom Tensile | Tej yam Endurance Limit |
| 304l ua | 68 ksg | 34 ksg |
| 304 | 70 ksg | 35 ksg |
| 321 | 76 ksg | 38 ksg |
Weldability ntawm 321 Stainless Hlau Tube
SS321 thiab TP321 tau zoo heev weldability, tsis tas yuav tsum tau preheating. Cov khoom ntim yuav tsum muaj cov khoom sib xws tab sis cov ntsiab lus siab dua alloy. Liquation cracking nyob rau hauv tshav kub cuam tshuam cheeb tsam: tsawg zog input. Fine grain loj. Ferrite ≥ 5%.
Pom zoo muab tub lim hlau yog SS 321, 347, thiab 348. Electrode yog E347 lossis E308L [kev pabcuam kub <370 ° C (700 ° F)].
Daim ntawv thov ntawm 321 Stainless Hlau Tube
Hom 321, 321H thiab TP321 tuaj yeem siv rau hauv qhov chaw uas muaj kev kho mob tom qab vuam tsis tuaj yeem, xws li cov kav dej thiab cov kav dej superheater thiab cov tshuab tso pa hauv cov tshuab reciprocating thiab roj turbines nrog qhov kub ntawm 425 txog 870 ° C (800 txog 1600 ° C. F). Thiab roj txhaj kab thiab hydraulic systems rau aircraft thiab aerospace tsheb.
