ASTM A269 UNS S32100 Hlau, kuj hu uaTIAB SA 321thiab raug xaiv los ntawm cov khoom siv naj npawb1.4541 TSI, yog ib qho corrosion-resistant austenitic stainless hlau nrog ib tug muaj pes tsawg leeg ua tib zoo crafted kom xa exceptional kev ua tau zoo nyob rau hauv ntau yam kev siv. Cia peb delve rau hauv qhov muaj pes tsawg leeg ntawm cov hlau no kom nkag siab zoo dua nws cov yam ntxwv tseem ceeb:
Chemical AISI 321 Composition (Percentage los ntawm Nyhav):
1. Carbon (C): 0.08 max
Tswj cov ntsiab lus ntawm cov pa roj carbon monoxide ua kom pom kev tiv thaiv corrosion thaum tuav lub zog kub.
2. Manganese (Mn): 2.00 max
Manganese pab txhawb rau lubcov ntaub ntawv 1.4541 aisisteel lub zuag qhia tag nrho lub zog thiab txhim khu nws workability.
3. Phosphorus (P): 0.045 max
Cov ntsiab lus phosphorus yog khaws cia kom tsawg los tiv thaiv brittleness thiab tswj cov hlau ductility.
4. Sulfur (S): 0.030 max
Tswj cov qib sulfur pab txhim kho machinability thiab tsis cuam tshuam qhov corrosion kuj ntawm cov hlau.
5. Silicon (Si): 0.75 max
Silicon txhim kho cov hlau tsis kam rau scaling ntawm qhov kub thiab txias.
6. Chromium (Cr): 17.0–19.{4}}
Chromium yog ib qho tseem ceeb ntawm cov alloying uas imparts corrosion kuj thiab high-temperature zog.
7. Nickel (Ni): 9.0–12.{4}}
Nickel contributes rau lubASTM A269 steel qib 1.4541tiv thaiv corrosion thiab muab kev ruaj ntseg ntawm qhov kub thiab txias.
8. Titanium (Ti): 5C min, 0.70 max
Titanium txhawb kev ruaj ntseg tiv thaiv carbide nag lossis daus thaum lub sij hawm vuam, txhim khu lubASTM A269 Gr tp321 welded rajtsis kam mus rau intergranular corrosion.
9. Columbium (Nb) + Tantalum (Ta): 10xC min, 1.00 max
Columbium thiab tantalum pab txhawb kom stabilization ntawm cov hlau, tiv thaiv rhiab heev thaum vuam.
10. Hlau (Fe): Sib npaug
Hlau ua lub hauv paus ntsiab lus nyob rau hauv lub alloy, muab qhov tsim nyog structural foundation.
ASTM A269 UNS S32100 Seamless Tube Cov yam ntxwv tseem ceeb:
1.4541 AISI 321 Corrosion Resistance:Kev sib xyaw ntawm chromium thiab nickel rendersASTM A269 UNS S32100 Cov Lus Qhiaheev resistant rau corrosion, ua rau nws haum rau daim ntaub ntawv nyob rau hauv nruj ib puag ncig.
High-Temperature Strength:Cov321 stainless hlau 1.4541alloy qhov muaj pes tsawg leeg ua kom muaj kev ua tau zoo ntawm qhov kub siab, ua rau nws tsim nyog rau kev siv hauv cov cua kub-txias thiab lwm qhov chaw kub kub.
Stability thaum vuam:Lub xub ntiag ntawm titanium, columbium, thiab tantalum minimizes carbide nag lossis daus, ua kom din 1.4541 stainless hlau stability thiab corrosion kuj nyob rau hauv welded cheeb tsam.
Vim nws lub zog siab thiab zoo heev corrosion kuj,ASTM A269 UNS S32100 Tubefeem ntau yog siv rau hauv kev lag luam xws li aerospace, chemical processing, food processing, and pharmaceuticals.Steel 1.4541 AISI 321muaj peev xwm tiv taus qhov kub thiab txias kuj ua rau nws tsim nyog rau cov ntawv thov uas cuam tshuam nrog kev kho cua sov, xws li cov khoom siv hluav taws xob thiab cov tshuab tso pa tawm.
