Khoom Txheej txheem cej luam
AISI 1117 yog aTsawg -} carbon, dawb {- tshuab xyawfaib rau hauv Asmeskas hlau thiab steel lub koom haum (AISI) qauv. Nws muaj ntau cov leej faj thiab phosphorus txhawm rau txhim kho machinability, ua rau haum rau qhov ntsuas ntsuas thiab cov ntawv thov xa xov uas yuav tsum tau ua cov khoom siv ntau.
Tshuaj Muaj Tshuaj
Cov tshuaj lom neeg cov tshuaj lom neeg ntawm AISI 1117 hlau yog:
| Lub ntsiab | Cov ntsiab lus (%) |
|---|---|
| Hlau, FE | 98.33 - 98.78 |
| Manganese, mn | 1.0 - 1.30 |
| Carbon, c | 0.14 - 0.20 |
| Sulphur, s | 0.080 - 0.13 |
| Phosphorous, p | 0.040 |
- Manganese (MN):1.00-1.30% (txhim kho kom muaj zog thiab cov tawv tawv)
- Cov pa roj carbon (c):0.14-0.20% (Cov ntsiab lus muaj cov pa roj carbon tsawg rau qhov zoo weldability thiab muaj peev xwm)
- Sulphur (s):0.08-0.13% (Ua kom muaj zog los ntawm kev sib sau Mns suav nrog)
- Phosphorus (p):Tsawg dua los yog sib luag rau 0.040% (txhim kho tshuab tab sis yuav txo cov qauv ductility)
- Hlau (FE):Seem
- Cov ntsiab lus Sulfur nce Sulfur nce zuj zus mus rau cov ntaub pua chaw Machinability tab sis yuav txo qis weldability thiab cuam tshuam.
Cov Khoom Siv Neeg Kho Tshuab
Cov cuab yeej siv cov khoom siv ntawm Aisi 1117 cov hlau roj teeb tau teev tseg hauv cov lus hauv qab no.
| Cov Khoom Siv | Me me | Muaj huab tais |
|---|---|---|
| Lub zog tensile | 475 MPa | 68900 psi |
| Paib lub zog | 400 mpa | 58000 psi |
| Loj modulus (raug rau hlau) | 140 GPA | Ksi |

| Poisson tus piv | 0.27-0.30 | 0.27-0.30 |
| Elongation thaum so (hauv 50 hli) | 15% | 15% |
| Txo thaj chaw | 40% | 40% |
| Hardness, Brinell | 137 | 137 |
| Hardness, Knoop (hloov dua siab tshiab los ntawm Brinell Hardness) | 156 | 156 |
| Hardness, Rockwell B (hloov dua siab tshiab los ntawm Brinell Hardness) | 75 | 75 |
| Hardness, vickers (hloov dua siab tshiab los ntawm brinell hardness) | 143 | 143 |
Cov Kev Siv Cov Ntawv Siv
AISI 1117 cov kav dej hlau siv hauv:
- Shafts, pins, thiab fasteners(machined Cheebtsam)
- Hydraulic Systems thiab qis {-} cov kua siab kom dej thauj
- Automotive tsis - tseem ceeb(bushings, spacers)
- Cov Machinery thiab Tuam Tshoj Cheebtsam
Fabrication Thiab Weldability
Machining:Zoo heev vim yog sulfur suav nrog.
Vuam:Tsis pom zoo rau cov khoom tseem ceeb velds (Sulfur ua rau kub tawg). Yog tias vuam yog qhov tsim nyog, preheating thiab qis - hydrogen electrodes yog qhia.
Cov Haujlwm Txias:Haum rau khoov thiab sib sau ua ke.
Kev tsim khoom thiab cov qauv
Hom yeeb nkab:Seamless lossis welded (ERW / hluav taws xob tiv thaiv welded).
Qauv:ASTM A53 (AVERM A106 (High {{{}}}}}} }lessless} mechanical tub tubing), g11170 (unsetch machining specifications.
Nto Kho:Feem ntau muab rau li - Kos duab, tig, lossis nrog tiv thaiv tiv thaiv (piv txwv li, roj, zinc plating).
Qhov zoo thiab cov kev txwv
Pros:Tus nqi -}}} Zoo, yooj yim rau lub tshuab, npaj muaj.
Cons:Kev txo cov tshuaj tiv thaiv corrosion (xav tau cov txheej txheej), lub zog tsawg rau high {{0} Pead Toting daim ntawv thov.
