AISI 1117 yog qhov tsawg-} Carbon sulph sulphur {}}}}}}}}}}}}} (AISI). Nws yog dav siv nyob rau hauv lub tshav pob ntawm tshuab kev tsim kho vim nws qhov kev txiav txim zoo heev, muaj zog nruab nrab thiab zoo machinity. Cov hauv qab no yog cov kev taw qhia qhia rau tus txheej txheem no:
I. Txuj ci tom qab thiab kev faib tawm
System uas:AISI 1117 yog tus qauv ntawm cov qauv ntawm Asmeskas hlau thiab steel koom haum (AISSING rau SAE Ec.17 hauv tus qauv SAE 161: SAE J403-2001 / 2014).
Hom Khoom:Tsawg -} Carbon sulphur {}}} {} {} Cov khoom siv hlau (s) thiab ib qho me me ntawm cov txhuas (PB).
Ii. Tshuaj Muaj Tshuaj
Cov tub ntxhais siv tshuaj muaj cov qauv tsim ntawm AISI 1117 lub hom phiaj los ua kom pom qhov sib npaug ntawm kev txiav cov kev ua tau zoo thiab muaj zog dua:
| Lub ntsiab | Cov ntsiab lus ntau (%) | Rooj mov |
| Carbon (c) | 0.14-0.20 | Paus muaj zog thiab hardness hauv |
| Manganese (mn) | 1.00-1.30 | Txhim kho cov khoom nyuaj thiab ua kom qab zib |
| Sulphur (s) | 0.08-0.13 | Cov ntaub ntawv mangorgese sulfide suav, txhim kho tshuab luam ntawv |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.040 | Tswj cov ntsiab lus impurity |
| Txhuas (PB) | Cov nyiaj $) | Ntxiv txo cov cuab yeej hnav thiab txhim kho nto tiav |
Nco tseg: Cov Sulfur cov ntsiab lus yog tus yuam sij rau nws lub tshuab luam ntawv, tab sis nws yuav cuam tshuam weldability (tshav kub yuav tsum tau nruj me ntsis tswj).
III. Lub cev thiab tshuab cov khoom siv
Kev ua haujlwm yooj yim
- Lub zog tensile:490-800 mpa (tuaj yeem ncav cuag cov kev txwv sab saud tom qab kev kho cua sov)
- Paib lub zog:390-415 MPA
- Elongation:Ntau dua los yog sib npaug rau 15% (analealed xeev)
- Hardness:120 HB (Annealed State), thiab tuaj yeem ncav cuag 167 - 217 HB nyob rau hauv txias-kos-kos lub xeev.
Cov tau zoo dua
- Kev Ua Tau Zoo: Manganese sulfide suav txo cov cuab yeej kev sib txhuam, txhawb nqa siab {}} ceev txiav, thiab txuas ntxiv cuab tam lub neej.
- Ua kev hloov tau: Haum rau precision kev ua xws li tig, milling thiab drilling, nrog qhov siab ua tiav.
- Kev Kho Cua Cua Sov:Kev ua tau zoo tuaj yeem hloov kho los ntawm cov txheej txheem xws li annealing thiab queming thiab Tensile lub zog tuaj yeem nce mus rau 800MPA tom qab quenching thiab tempering).
IV. Kev Kho Cua Sov
Kev kho cua sov yog qhov txuas tseem ceeb hauv kev ua tau zoo:
- Ib tug anerting: Tuav ntawm 780-8 Qib thiab txias maj mam kom txo tawv tawv rau 120 HB, txhim kho kev sib zog thiab ua kom zoo dua conduction thiab ua kom zoo dua machinability.
- Quenching thiab tempering (quenching + tempering):
- Quenching: dej lossis roj txias rau ntawm 850-880 qib kom tau txais cov qauv martensitic;
- Tempering: tuav ntawm 500-600℃kom sib npaug lub zog thiab tawv.
- Normalizing:Txhim kho cov kev sib txuam ntawm cov qauv thiab yog tsim nyog rau tom ntej txias ua haujlwm.
V. Cov Ntawv Thov
AISI 1117 tau siv dav hauv cov khoom sib xyaw uas yuav tsum tau siab - precision txiav thiab nruab nrab loads:
- Neeg kho tshuab tsim:Shafts, zog, pins, bolts, bolts thiab lwm yam uas yuav tsum tau ua kom precision.
- Kev Lag Luam Automotive:Cov khoom sib kis tau sib kis, braking system seem, cov kauj txheej.
- Seev thiab meters:Hnav {{0-} Cov ntu tiv taus carburized, qhov chaw carburized (nto hardening (nto hardening + tseem nruj heev).
- Cov txheej txheem dav dav:Tsis {{0} butter -} bearing nkhaus nkhaus tshuab.
VI. Ceev faj rau kev siv
Vuam Performance
Cov Sulfur cov ntsiab lus siab yog nquag ua rau muaj cov kab nrib pleb kub, thiab tsawg dua li cov pa thaiv cov vuam) yuav tsum tau coj los ua kom zoo nkauj thiab ua ntej.
Ib puag ncig kev yoog
Nws muaj kev tiv thaiv corrosion tsis muaj zog thiab yuav tsum muaj galvanization lossis pleev xim rau kev tiv thaiv ib puag ncig.
Zam kev siv nyob rau hauv qis - kub (<-40℃) or high-impact scenarios (with limited toughness).
Kev tiv thaiv kev nyab xeeb
Lead -} muaj cov versions yuav tsum tau tiv thaiv los ntawm cov plua plav plua plav (cov khoom siv tiv thaiv yuav tsum hnav thaum ua haujlwm).
Lub ntsiab
Tus tseem ceeb ntawm Aisi 1117 lus dag hauv kev sib npaug txiav kev ua tau zoo thiab cov kws kho tshuab, thiab nws tsim tshwj xeeb rau qhov ntsuas qhov chaw hauv ntau lawm. Nws cov kev txwv (xws li weldability thiab corrosion tsis kam) yuav tsum tau them nyiaj rau los ntawm kev txhim kho kom zoo thiab ua kom zoo. Thaum xaiv hom, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account lub thauj khoom, ib puag ncig thiab kev kho kom haum thiab tiv thaiv kev kub ntxhov ntawm cov khoom siv.
