AWS E309 RAWS LI HLAU (AS -} welded mob)
E309 Stainless Hlau Hauv Hlau (Annealed Mob)
| Cov Khoom Taw Qhia | Tus Nqi Muaj Ntau | Ib yam | Qauv / Mob | Hais lus |
|---|---|---|---|---|
| Lub zog tensile | 515–620 | MPa | ASTM A959 | Annealed daim hlau / tuav; tuaj yeem nce ntxiv rau 620 mpa tom qab ua haujlwm txias |
| Paib lub zog | 205–310 | MPa | ASTM A959 | Tus nqi raug nyob hauv kev tsis ntseeg; txias -} Cov hlau ua haujlwm tuaj yeem ncav cuag 310 mpa |
| Elongation | 30–40% | - | ASTM A959 | Ntau dua elongation (40%) rau annealed daim hlau; txo qis rau 30% tom qab ua haujlwm txias |
| Brinell hardness | 170–212 | HBW | Kev Lag Luam Cov Ntaub Ntawv | Tsis hardness hauv annealed mob; yuav nce me ntsis tom qab daws kev kho mob |
| Siab - kub tensile lub zog | 400-500 (ntawm 600 degree) | MPa | Kev Lag Luam Cov Ntaub Ntawv | Vim nws cov pa roj carbon ntau, 309h muaj 10% siab dua lub zog tshaj 309 lub hauv paus hlau ntawm 600 degree |
| Cov Khoom Taw Qhia | Tus Nqi Muaj Ntau | Ib yam | Qauv / Mob | Hais lus |
|---|---|---|---|---|
| Lub zog tensile | 593–620 | MPa | Aws A5.9 | Rau er309 vuam hlau, hauv qab Argon- daim ntaub thaiv vuam vuam, tus nqi raug rau hauv raws li {2} welded mob |
| Paib lub zog | 393–400 | MPa | Aws A5.9 | 0.2% offset muab lub zog zog; Cov ntaub ntawv rau er309l xaim yog me ntsis qis dua (kwv yees li 393 mpa) |
| Elongation | 34–47% | - | Aws A5.9 | Raws li -} Welded tso hlau; Er309l tuaj yeem ncav cuag ib qho elongation ntawm 47% vim nws qhov qis- cov cuab yeej carbon |
| Elastic modulus | 200 | GPA | Aws A5.9 | Zoo ib yam li Austenitic Stainless Hlau Law Hlau |
| Brinell hardness | 180–220 | HBW | Kev Lag Luam Cov Ntaub Ntawv | Moderate hardness nyob rau hauv li -} welded mob; tej zaum yuav nce mus rau 231 HBW tom qab kev kho cua sov |
Kev sib piv ntawm E309L thiab E309H cov khoom sib txawv
| Cov Khoom Taw Qhia | E309L (Tsawg -} hom carbon hom) | E309H (High-} hom carbon hom) | Ib yam | Qauv / Mob | Vim li cas qhov sib txawv |
|---|---|---|---|---|---|
| Lub zog tensile | 590–610 | 620–650 | MPa | Aws A5.9 | E309H muaj cov ntsiab lus muaj roj carbon ntau dua (0.04-0.08%), txhim kho siab- lub zog kub tab sis me ntsis txo corrosion tsis kam |
| Elongation | 40–47% | 30–35% | - | Aws A5.9 | Cov pa roj carbon txo qis kev pheej hmoo ntawm kev pheej hmoo ntawm kev txhim kho corrosion tab sis me ntsis qis qis zog; Cov pa roj carbon ntau txhim kho siab - kub creep Kuj |
| Intergranular corrosion tsis kam | Zoo tshaj | Tswj kav | - | Kev Lag Luam Cov Ntaub Ntawv | E309L muaj cov ntsiab lus carbon tsawg dua lossis sib npaug rau 0.03%, txo qis carbide nag lossis daus |
| High - kub siv tau | Dav dav (tsawg dua los yog sib npaug nrog 500 degree) | Zoo heev (tsawg dua los yog sib npaug nrog 700 degree) | - | Kev Lag Luam Cov Ntaub Ntawv | E309H yog qhov tsim nyog rau muaj cov chaw so muaj kev lag luam, siab- kub vessels, thiab yuav tsum tau kho cua sov |
