AISI 1030 Steel yog dab tsi?
AISI/SAE 1030 yog anruab nrab carbon steelmuaj li ntawm 0.28% mus rau 0.34% carbon, nrog manganese ntawm 0.60% thiab 0.90%. Nws belongs rau tsev neeg cov pa roj carbon steel thiab ib txwm muab rau hauv kub- dov, txias- rub, tig- thiab - polished lossis centreless - hauv av. Qib yog xaiv qhov uas yuav tsum tau muaj qhov sib npaug ntawm lub zog, hardness thiab hnav tsis kam, thaum khaws cov khoom siv tau zoo thiab weldability. Vim tias nws cov ntsiab lus carbon nyob nruab nrab ntawm qis- qib carbon xws li 1018 thiab 1020 thiab siab dua- cov pa roj carbon qib xws li 1045, 1030 tau kho dav dav raws li kev dav dav- lub hom phiaj engineering steel.
Chemical Composition thiab Mechanical Properties
Qhov sib xyaw ua ke thiab cov cuab yeej cuab tam rau AISI 1030 yog cov ntsiab lus hauv qab no. Cov txiaj ntsig tiag yog nyob ntawm daim ntawv ntawm cov khoom lag luam, qhov loj me thiab cov khoom xa tuaj, thiab cov khoom siv tshwj xeeb yuav tsum tau hais txog ib qho kev txiav txim.
| Yam khoom | Tus nqi |
|---|---|
| Cov pa roj carbon (C) | 0.28 - 0.34% |
| Manganese (Mn) | 0.60 - 0.90% |
| Phosphorus (P), max | 0.040% |
| Sulfur (S), max | 0.050% |
| Tensile zog | 500 - 850 MPa nyob ntawm qhov mob |
| Yield zog | Kwv yees li ntawm 370 - 500 MPa |
| Brinell hardness | 150 - 245 HB |
| Elongation | Kwv yees li ntawm 12 - 20% nyob ntawm qhov xwm txheej |
Nco ntsoov tias ib qho kev xav tsis zoo yog tias 1030 yog cov pa roj carbon siab. Nrog 0.28% rau 0.34% carbon nws raug cais raws linruab nrab carbon steel; high carbon steels feem ntau muaj ntau tshaj li 0.55% carbon.
1030 Piv nrog 1018, 1020 thiab 1045
Kev xaiv ntawm cov qib no nyob ntawm qhov xav tau lub zog, ductility thiab weldability. Cov lus hauv qab no qhia txog qhov sib txawv tseem ceeb.
| Qib | Cov ntsiab lus carbon | Cov yam ntxwv tseem ceeb |
|---|---|---|
| TIAB SA 1018 | 0.15 - 0.20% | Tsawg carbon; zoo heev ductility thiab weldability; soft thiab formable; haum rau cov tsis- qhov tseem ceeb |
| TIAB SA 1020 | 0.17 - 0.23% | Tsawg carbon; zoo weldability; nruab nrab lub zog; yooj yim machining |
| TIAB SA 1030 | 0.28 - 0.34% | Nruab nrab carbon; siab zog, hardness thiab hnav tsis kam; teb zoo rau kev kho cua sov |
| TIAB SA 1045 | 0.43 - 0.50% | Nruab nrab carbon; nyuaj thiab muaj zog tshaj 1030; qis ductility; tsawg haum rau kev vuam hnyav |
Kev kho cua sov thiab Fabrication Notes
1030 steel tuaj yeem ua kom muaj zog los ntawm kev ua haujlwm txias thiab los ntawm kev kho cua sov. Normalizing refines cov qauv nplej thiab txhim kho qhov sib xws ua ntej machining, thaum quenching thiab tempering tuaj yeem nce hardness rau hnav -cov ntaub ntawv resistant. Nyob rau hauv qhov zoo li - dov cov hlau muaj zog thiab hardness. Rau vuam, preheating feem ntau pom zoo rau qhov hnyav dua, thiab qis -hydrogen vuam consumables pab kom tsis txhob hydrogen-induced cracking.
Cov ntawv thov siv
Cov ntawv thov muaj xws li cov ncej, spindles, studs, bolts, zog, pinions, tshuab cuab yeej, cov khoom siv tsheb thiab cov tshuab dav dav uas yuav tsum muaj lwm txoj hauv kev rau 1018 lossis 1020. Nws kuj yog siv rau cov welded sib dhos uas yuav tsum tau muaj zog sib koom ua ke ntau dua li qis - qib carbon tuaj yeem muab tau.
Cov lus nug nquag
Puas yog 1030 carbon tsawg lossis nruab nrab carbon steel?
Nws yog nruab nrab carbon steel. Nws cov ntsiab lus carbon ntawm 0.28% mus rau 0.34% tso nws siab tshaj qis - carbon qib xws li 1018 thiab 1020.
1030 steel puas tuaj yeem welded?
Yog, 1030 muaj kev ncaj ncees weldability. Preheating thiab qis - hydrogen electrodes raug pom zoo, tshwj xeeb tshaj yog rau cov ntu tuab, kom txo qis kev pheej hmoo ntawm kev tawg.
Qhov txawv ntawm 1030 thiab 1045 yog dab tsi?
Qhov sib txawv tseem ceeb yog cov ntsiab lus carbon: 1030 muaj txog 0.30% carbon thaum 1045 muaj txog 0.45%. Cov ntsiab lus carbon ntau dua ua rau 1045 nyuaj thiab muaj zog dua tab sis tsis muaj zog.
Puas yog 1030 teb rau kev kho cua sov?
Yog lawm. Nws tuaj yeem ua tau zoo li qub, thiab quench-thiab- kev kho mob tuaj yeem ua rau nws qhov nyuaj thiab lub zog rau kev thov.
1030 steel siv rau dab tsi?
Nws yog feem ntau siv rau shafts, gears, studs, bolts thiab cov khoom siv dav dav uas xav tau qhov sib npaug zoo ntawm lub zog, hardness thiab machinability.
