C360 thiab C464 Cov Khoom Copy -} kev paub

1. Tshuaj lom neeg sib xyaw (qhov sib txawv)

Qhov sib txawv ntawm kev sib txawv nyob rau hauv lub xub ntiag ntawmTin (Sn)(Tsis sib xws rau C464) thiab kev hloov pauv ntawm tooj liab (Cu), zinc (zinc (zinc), thiab txhuas (pb) cov ntsiab lus. Cov ntsiab lus ncaj qha txhais cov alloy txoj kev ua tau zoo. Qhov tseem ceeb ua ke nrog cov qauv kev lag luam (piv txwv li, ASTM B16 rau tooj dag):

Lub ntsiab	C360 (Dawb -} Txiav cov tooj hlau; unc unicity c36000)	C464 (Naval tooj dag; tsis yog C46400)	Ntsiab lus tseem ceeb
Tooj Liab (Cu)	60.0 – 63.0%	60.0 – 63.0%	Cov ntsiab lus tooj liab zoo ib yam, muab cov hauv paus rau kev ua kom zoo nkauj thiab corrosion tsis kam.
Zinc (Zn)	Tshuav Nyiaj (≈35 - 38%)	34.0 – 37.0%	C360 muaj qhov me ntsis zinc (boosts muaj zog tab sis yuav txo corrosion tsis kam).
Txhuas (PB)	2.5 – 3.7%	0.2% max (trace)	Tseem ceeb sib txawv: C360 muaj cov hmoov txhuas loj rau cov tshuab luam ntawv zoo tshaj; C464 yog tsawg {- lek} Hmoov txhuas (zam kev ua yeeb yam hauv high- kev siv ntxhov siab).
Tin (Sn)	0.1% max (trace)	0.5 – 1.0%	Txawv rau C464: Tin yog txhob txwm ntxiv rau txhim kho corrosion tsis kam (tshwj xeeb tshaj yog tawm tsam ntsev) thiab txhim kho lub zog.
Hlau (FE)	0.15% Max	0.15% Max	Cov hlau tsis muaj hlau tsawg hauv ob qho tib si kom tiv thaiv kom tsis txhob muaj brittleness.

2. Cov Khoom Siv Neeg Kho Tshuab

Kev sib xyaw sib txawv qhov tshwm sim hauv kev sib txawv hauv lub zog, hardness, thiab ductility (qhov tseem ceeb qhia rau annealed tej yam kev mob, tshwj tsis yog sau):

Ntiag tug	C360 (Anealed)	C464 (anealed)	Tseem Ceeb Takaway
Lub zog tensile	~ 414 MPa (60,000 psi)	~ 448 MPA (65,000 PSI)	C464 yog ~ 8% muaj zog dua, ua tsaug rau Tin ntxiv.
Tawm Zog (0.2% offset)	~ 172 MPA (25,000 PSI)	~ 193 MPa (28,000 PSI)	C464 tsis kam lees kev ua kom tiav zoo dua hauv kev thauj khoom.
Brinell Hardness (HB)	~85	~95	C464 yog qhov nyuaj dua, txhim kho cov hnav tsis kam rau cov txheej txheem.
Elongation (hauv 50 hli)	~30%	~25%	C360 muaj ntau dua c360 (yooj yim dua khoov / daim ntawv) vim muaj cov taug txhuas siab dua thiab qis dua.
Qaug zog muaj zog	Qis dua (nquag rau kev ntxhov siab tawg rau hauv high - phoo ntawv cycles)	Siab dua (tin txhim kho kom rov muaj kev ntxhov siab ntau dua)	C464 yog qhov zoo dua rau cov ntu hauv qab cyclic loads (piv txwv li, marine Cheebtsam).

3. Machinability

Luam ntaub pua chaw (puab nrog cov cuab yeej) yog qhov sib txawv, tsav los ntawm cov ntsiab lus txhuas:

C360: Lub npe hu ua "free {-} Txiav cov cim txhuas (2.5-3. Nws ua kom huv si, nti {- kev txiav dawb, minimizes twj ris, thiab ua rau muaj kev ntau lawm} ceev ntau lawm. Nws yog ib qho ntawm cov taum tooj ntau tshaj plaws alloys, zoo tagnrho rau precision, siab {8}- ntim qhov.

C464: Cov ntsiab lus txhuas qis (tsawg dua los yog sib npaug rau 0.2%) ua rau nws lub tshuab luam ntawvTseem Ceebdua C360. Txiav C464 yuav tsum tau qeeb qeeb nrawm, cov cuab yeej sib haum, thiab ntau cov cuab yeej siv tau hloov pauv kom tsis txhob muaj kev kub ntxhov lossis tsis zoo. Nws tsis yog tsim rau high - ntim tshuab tab sis rau kev ua haujlwm txheej txheem.

4. Corrosion Kuj

Corrosion tsis kam yog qhov tseem ceeb rau cov ntawv thov nthuav tawm kom noo los yog tshuaj lom {{}}}- hloov:

C360: Muajzoo dav dav corrosion tsis kam(Xws li, hauv huab cua, dej tsis huv, lossis tshuaj me me) tab sis tawm tsam ntawm cov chaw hnyav. Nws yog qhov ntxim rauDEZINCICATION(Zinc Leaching tawm, tawm hauv cov tooj liab) hauv cov khoom noj sillab) hauv cov zaub mov tsis huv, thiab cov ntaub ntawv sib tiv tauj lossis cov khoom siv tau muaj).

C464: Cais raws li "Naval tooj dag," nws cov tin ntxiv muabzoo heev corrosion{{0 {}}}}} marine cua, thiab cov tshuaj muaj khoom lag luam me me. Nws tseem tiv thaiv Dezincification zoo dua C360, ua nws ib qho staple rau cov kev siv tubrog nkoj thiab dej hiav txwv.
