Yam khoom twg yog 803 incoloy -} kev paub

1. Dab tsi cov khoom siv yog incoloy 803

Incoloy 803 (tsis yog N08803) yog aNickel -} cov hlau- chromium (ni-} cr) alloyTshwj xeeb engineered rau high - cov ntawv thov kub. Nws belongs rau qhov dav "incoloy" tsev neeg- Ntau ntawm cov tshuab tshwj xeeb muaj zog

Tsis zoo li qee qhov corrosion - Tsom nias qib (piv txwv li, Incoloy 825), Incoloy 803 yog qhov zoo rauhigh - kub ntsuas - bearing beararariosCov. Nws qhov tseem ceeb Niche yog nyob rau hauv cov ntawv thov uas cov khoom siv cua sov, kev ntxhov siab ntau, hluav taws xob ua haujlwm, thiab cua sov kev lag luam spy. Ib qho kev txhais tau yog nws cov coefficient ntawm thermal expansion (CTE) kev kub ntxhov, uas yog minimizing cyclots rau kev tiv thaiv kev tawg lossis deformation hauv cyclic thermal.

2.What yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm incoloy 803?

Cov tshuaj lom neeg muaj kuab lom ntawm incoloy tswj tau kom ua tiav nws lub siab- kub ua kev ua tau zoo li ASTM B829 (rau seamless yeeb / raj) thiab ASTM B830 (rau phaj / ntawv). Hauv qab no yog qhov raug thiab ntau tshaj / tsawg kawg ntawm nws cov ntsiab lus tseem ceeb (txhua qhov tseem ceeb hauv qhov hnyav feem pua, wt%):

Lub ntsiab	Tsawg li tsawg tau	Ntau tshaj plaws	Zoo li ib txwm	Rooj mov
Npib tsib caug (ni)	30.0%	35.0%	32.5%	Txhim kho siab - kub lub zog thiab ductility; resistays thermal rog.
Hlau (FE)	Seem	Seem	~50.0%	Txo tus nqi vs. Nickel - ric nplua nuj superalloys; tswj cov qauv kev ruaj ntseg.
Chromium (cr)	27.0%	30.0%	28.5%	Cov foos ib ntom chromium oxide (cr₂o₃) zaj duab xis; Muab oxidation / corrosion tsis kam ntawm temps High.
Carbon (c)	0.03%	0.08%	0.05%	Ntxiv dag zog rau alloy ntawm carboide nag lossis daus; tswj kom tsis txhob muaj kev tsim kom muaj carbide ntau (uas tuaj yeem txo cov ductility).
Aluminium (AL)	0.15%	0.60%	0.35%	AIDS hauv kev tsim cov tshuaj tiv thaiv txhuas oxide (al₂o₃) txheej; Boosts siab siab - kub oxidation tsis kam.
Titanium (ti)	0.15%	0.60%	0.35%	Precipitates raws li titanium carbides (TIC) lossis intermetallics; Txhim kho lub zog nkag mus (tsis kam mus rau qeeb deformation nyob rau hauv kev kub siab / kev ntxhov siab).
Manganese (mn)	-	1.0%	0.5%	Txhim kho cov haujlwm kub; Txo brittleness thaum ua tiav.
Silicon (si)	-	1.0%	0.4%	AIDS nyob rau deoxidation thaum lub sijhawm tsim khoom; Txhawb oxide zaj duab xis tsim.
Phosphorus (p)	-	0.025%	0.015%	Tswj hwm qib qis; minimizes brittleness, tshwj xeeb tshaj yog thaum muaj kub.
Sulphur (s)	-	0.015%	0.005%	Nruj me ntsis txwv; Txo txoj kev pheej hmoo ntawm kub tawg thaum vuam / ua.

3. Dab tsi yog qhov nyuaj ntawm Incoloy 803?

Hardness ntawm incoloy 803 feem ntau ntsuas kev siv covBrinell Hardness Test (HB)lossisRockwell Hardness Ntsuas (Feem ntau Rockwell B, HRB)- Txheem haum rau nws cov qauv hardness Hardness values sib txawv me ntsis raws liKev Kho Cua Sov Lub Xeev, raws li kev ua thermal cuam tshuam rau cov almoy lub microlo microstructure (piv txwv, carbide faib).

Lub hardness harues los ntawm kev kho cua sov:
