Aluminium alloy 5059muaj ntau yamtemper xaiv, txhua tus tailored kom sib npauglub zog, toughness, thiab corrosion kuj. Xaiv txoj kev npau taws yog qhov tseem ceeb raumarine, offshore, thiab structural applications. Nov yog cov ncauj lus kom ntxaws:
Txheej txheem cej luam ntawm 5059 Tempers
5059 yog ib feem ntawm lubAl-Mg-Mn alloy tsev neeg. Tsis zoo li cov cua sov- kho tau cov alloys, nws yoglim- tawv, yog li tempering feem ntau muajua haujlwm txias thiab txo kev ntxhov siabes tsis yog kev kho cua sov. Common 5059 tempers muaj xws li:
| Kub | Kev piav qhia | Tej kev siv |
|---|---|---|
| H321 | Lim- hardened thiab stabilized (resistant rau kev nyuaj siab corrosion cracking) | Nkoj hulls, offshore platforms, marine structures |
| H111 | Txias me ntsis -ua haujlwm (lub teeb tawv tawv) | Cov khoom siv nruab nrab, cov khoom siv marine |
| O | Annealed (tag nrho soft) | Kev tsim, khoov, cov duab nyuaj ua ntej ua haujlwm ntxiv |
Kev cuam tshuam ntawm Temper rau Mechanical Properties
| Kub | Yield zog (MPa) | Qhov kawg Tensile Strength (MPa) | Elongation (%) | Sau ntawv |
|---|---|---|---|---|
| H321 | ~275–300 | ~370–390 | 12–15 | High SCC tsis kam, khaws kev tiv thaiv corrosion |
| H111 | ~195–215 | ~330–360 | 18–22 | Ua kom yooj yim dua, lub zog qis dua H321 |
| O | ~120 | ~280 | 25–30 | Maximum ductility, tsawg kawg residual stress |
Ntsiab Lus:Siab dua -lub zog tempers nyiamH321muab cov qauv kev ua tau zoo dua hauvsiab -kev nyuaj siab nyob rau hauv marine ib puag ncig, thaumO los yog H111 temperssiv thaumformabilityyog qhov tseem ceeb.
Kev cuam tshuam ntawm Temper rau Corrosion Resistance
H321:Zoo heev tiv tausKev ntxhov siab corrosion cracking (SCC)thiab pitting hauv seawater. Nyiam raudaim ntawv thov offshore.
H111:Tsawg SCC tsis kam tshaj H321 tab sis tseemzoo rau nruab nrab marine raug.
O (ntxiv):Tuav lub cev tiv thaiv corrosion tab sis yogmechanically tsis muaj zog, tsis zoo tagnrho rau cov qauv kev ntxhov siab.
Tswv yim:Yog tias yuav tsum tau vuam, tom qab -weld stress relief yog pom zoo kom tswjH321 zoo li corrosion ua haujlwmnyob rau hauv welded aav.
Phau Ntawv Qhia Xaiv Tswv Yim
Shipbuilding hulls: H321
Marine tanks & cia:H321 los yog H111 nyob ntawm thickness
Tsim los yog khoov Cheebtsam:O lossis H111, ces txias - ua haujlwm rau H321 yog xav tau lub zog
High -lub zog offshore qauv:H321, qee zaum nrog anodized nto rau kev tiv thaiv corrosion ntxiv
