Chav-Tsuas Cov Cuab Yeej Cuab Yeej ntawm Incoloy 800 (UNS N08800)
1. Lub zog tensile
Txhais: Qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus ua ntej kev sib tsoo tensile nyob rau hauv axial loading.
Tus nqiUa haujlwm siab: 550-650 MPa
Yam tsawg kawg nkaus Specification Requirement:
ASTM B409 / B408 / B564 / ASTM B409 / B408 / B564 / TS: Ntau dua lossis sib npaug li 450 MPa
EN 10095 (Qib X5NiCrAlTi31-20, 1.4876): Ntau dua lossis sib npaug li 450 MPa
GB/T 24511 (Qib NS1101): Ntau dua lossis sib npaug li 440 MPa
Nco tseg: Ntau dua tensile zog qhov tseem ceeb yuav raug pom nyob rau hauv txias- ua hauj lwm variants ntawm Incoloy 800, tab sis lub xeev annealed yog nyiam rau feem ntau siab - kub daim ntawv thov vim nws sib npaug kev ua tau zoo.
2. Yield Strength (0.2% Offset)
Txhais: Qhov kev ntxhov siab ntawm cov khoom siv ua rau cov yas deformation mus tas li ntawm 0.2% txheeb ze rau nws qhov ntsuas qhov ntev.
Tus nqiUa haujlwm siab: 200-270 MPa
Yam tsawg kawg nkaus Specification Requirement:
ASTM Txuj: Ntau dua lossis sib npaug li 170 MPa
TS EN 10095: Ntau dua lossis sib npaug li 170 MPa
GB/T 24511: Ntau dua lossis sib npaug li 170 MPa
Nco tseg: Lub zog tawm los yog qhov tseem ceeb rau kev tsim qauv, raws li nws txiav txim siab qhov siab tshaj plaws ntawm cov khoom tiv thaiv tuaj yeem dais yam tsis muaj deformation mus tas li.
3. Elongation (hauv 50 mm Gauge Length)
Txhais: Qhov feem pua ntawm cov elongation mus tas li ntawm cov khoom siv lub ntsuas qhov ntev tom qab tensile tawg, xav txog nws cov ductility.
Tus nqi: 35–45%
Yam tsawg kawg nkaus Specification Requirement:
ASTM Txuj: Ntau dua lossis sib npaug li 30%
TS EN 10095: Ntau dua lossis sib npaug li 30%
GB/T 24511: Ntau dua lossis sib npaug li 30%
Nco tseg: High elongation ua rau Incoloy 800 haum rau kev tsim cov txheej txheem xws li dabtsi yog khoov, dov, thiab sib sib zog nqus kos duab, uas yog feem ntau siv nyob rau hauv manufacturing tshav kub exchangers thiab lub cub tawg Cheebtsam.
4. Hardness
Brinell Hardness (HBW, 500 kgf load, 10 hli pob): 130–180 HWB
Rockwell Hardness (HRB, 100 kgf load, 1/16 nti pob): 60–80 IB
Nco tseg: Hardness qhov tseem ceeb yog inversely cuam tshuam rau ductility; cov hardness siab dua feem ntau sib raug rau qis elongation, tshwj xeeb tshaj yog nyob rau hauv txias - cov ntaub ntawv ua haujlwm.
5. Cov cuab yeej cuab tam ntxiv (txo thaj tsam)
Txhais: Qhov feem pua ntawm qhov qub ntoo khaub lig- ntu ntu txo qis tom qab tensile tawg.
Tus nqi: 60–70%
Yam tsawg kawg nkaus Specification Requirement: Ntau dua lossis sib npaug li 40% (ASTM thiab EN cov qauv)
