ASTM A519 Qib 1330 Tubing yog dab tsi
ASTM A519 qib 1330 yog ib qho nruab nrab -carbon, siab -manganese mechanical tubing qib sau npe nrog UNS tus lej G13300. Cov pa roj carbon monoxide muaj nyob rau hauv 0.28-0.33% ntau thiab manganese tau nce mus rau 1.60-1.90%, kwv yees li peb npaug ntawm qib pom hauv cov qib carbon. Manganese yog cov khoom kim tshaj plaws uas txhim kho hardenability hauv steel, yog li qib 1330 muaj txiaj ntsig los ntawm - cov lus teb nyuaj rau cov ntu nruab nrab yam tsis muaj nqi ntawm chromium, nickel lossis molybdenum ntxiv.
Kev sib xyaw ua ke ntawm cov pa roj carbon monoxide thiab siab manganese ua rau cov hlau uas tshuab tau zoo nyob rau hauv cov txheej txheem annealed lossis normalized thiab tom qab ntawd teb cov lus pom zoo rau quenching thiab tempering. Nws yog dav siv nyob rau hauv machinery qhov twg ib tug ncej los yog lub tes tsho yuav tsum nqa ib tug nruab nrab load tom qab tshav kub kev kho mob thiab qhov twg cov economics ntawm ib tug tsawg- alloy qib teeb meem.
Chemical Composition thiab Hardenability
| Element | ASTM A519 Qib 1330 |
| Cov pa roj carbon | 0.28–0.33% |
| Manganese | 1.60–1.90% |
| Phosphorus | 0.040% max |
| Sulfur | 0.050% max |
ASTM A519 tabulates qhov tsawg kawg nkaus tensile lub zog, yield zog thiab elongation rau txhua qib thiab tus me nyuam mob, yog li cov nqi hais rau ib tug 1330 raj nyob ntawm seb nws puas tau muab kub tiav, txias los yog kub kho. Nws yog ib qho kev xyaum ua kom cov tubing annealed rau machining thiab tom qab ntawd kom harden thiab temper qhov tiav, uas tso cai rau kev kho cua sov zaum kawg teeb tsa cov khoom tsis yog lub raj zeb.
Cov ntsiab lus siab manganese yuav tsum raug coj mus rau hauv tus account thaum cov hlau raug txiav los yog welded. Cov qib yog nruj dua thiab ua haujlwm nyuaj dua li cov pa roj carbon steel ntawm cov pa roj carbon zoo sib xws, yog li txiav nrawm thiab txau yuav tsum tau teeb tsa raws li, thiab cov seem uas yuav tau txais txiaj ntsig los ntawm kev tswj hwm preheat thiab qeeb qeeb.
Qhov ntau thiab tsawg, Tolerances thiab cov ntawv yuav khoom
Qib 1330 yog tsim los ua seamless tubing thoob plaws ntau yam ntawm sab nraud diameters thiab phab ntsa thicknesses, thiab qhov ntev kam rau ua, ncaj thiab ntev txoj cai los ntawm ASTM A519 rooj. Kev txiav txim rau cov cua sov- cov khoom kho tau yuav tsum tau hais txog qhov kev xa khoom, qhov yuav tsum tau muaj zog los yog lub zog ntau tom qab kev kho cua sov thiab kev kuaj xyuas. Qhov twg lub hardened ib feem yuav machined tom qab kev kho mob, lub raj yuav tsum tau txiav txim nrog txaus Tshuag kom tso cai rau distortion thaum lub sij hawm quenching.
Tej kev siv
Tsav shafts, qag shafts thiab stub shafts nyob rau hauv off-txoj kev loj thiab kev ua liaj ua teb machinery
Lub tes tsho, bushings thiab dab tshos rau nruab nrab - thauj cov kabmob
Gear blanks, sprocket hubs thiab coupling lub cev ua los ntawm tube Tshuag
Pins, khi rods thiab txuas qhov chaw hauv kev tsim kho thiab cov khoom siv tuav
Pwm ejector Cheebtsam thiab tshuab cuab yeej accessories nyob rau hauv lub quenched thiab tempered mob
Kev kho cua sov thiab kev coj ua
Cov kab ke ib txwm yog kom normalize lub raj ua ntej machining, ces austenitize, quench nyob rau hauv cov roj thiab npau taws rau qhov yuav tsum tau muaj zog thiab toughness. Normalizing refines lub grain qauv thiab muab ib tug uniform, ntau machinable mob. Roj quenching yog nyiam dua dej quenching, vim hais tias cov ntsiab lus ntawm manganese siab muab txaus hardenability thaum lub softer quench txwv txoj kev pheej hmoo ntawm tawg thiab distortion. Tempering kub yog xaiv nyob rau hauv ib txwm muaj rau nruab nrab - carbon steels, nrog qis kub muab lub zog siab dua thiab kub siab dua muab cov toughness zoo dua.
Rau machining, coated carbide tooling yog siv nyob rau hauv nruab nrab txiav speeds nrog ib tug zoo rake geometry, thiab ib tug hnyav pub yog preferable rau lub teeb rubbing txiav vim hais tias cov khoom ua hauj lwm hardens. Weldability tau txais tab sis tsis sib npaug ntawm cov qib qis - carbon qib: preheat hauv cheeb tsam ntawm 200-300℃ua ke nrog kev tswj xyuas qeeb qeeb tom qab vuam txo qhov kev pheej hmoo ntawm ib qho nyuaj, tawg -rhiab kub cuam tshuam cheeb tsam.
FAQ
Q: Dab tsi ua rau qib 1330 txawv ntawm cov pa roj carbon monoxide xws li 1035?
Nws yog qib manganese. Manganese ntawm 1.60–1.90% txhim kho hardenability, yog li 1330 tivthaiv tuaj yeem dhau los ntawm -hardened ntawm cov seem uas cov pa roj carbon steel ntawm cov ntsiab lus zoo sib xws yuav harden tsuas yog nyob rau saum npoo.
Q: ASTM A 519 1330 tubing feem ntau raug kho li cas?
Feem ntau los ntawm normalizing ua ntej machining thiab ces austenitizing, roj quenching thiab tempering tom qab machining. Tempering kub yog xaiv los muab lub zog thiab cuam tshuam toughness xav tau los ntawm qhov tiav.
Q: Puas yog dej quenching haum rau qib 1330?
Roj quenching yog ib txwm ua. Cov ntsiab lus manganese muab txaus hardenability rau nruab nrab seem, thiab cov roj quench qeeb txo qhov kev pheej hmoo ntawm quench cracking thiab distortion piv nrog ib tug dej quench.
Q: 1330 tubing puas tuaj yeem welded?
Nws tuaj yeem welded nrog cov txheej txheem tsim nyog, tab sis nws tsis yog qib qis - carbon welding qib. Lub preheat ntawm kwv yees li 200-300℃thiab tswj qeeb txias tom qab vuam yog pom zoo kom tsis txhob muaj ib qho nyuaj kub cuam tshuam cheeb tsam.
Q: Cov cuab yeej siv tshuab dab tsi ASTM A519 xav tau rau qib 1330?
Cov lus qhia tshwj xeeb teev qhov tsawg kawg nkaus tensile lub zog, tawm los lub zog thiab elongation rau txhua qib thiab txhua qhov kev xa khoom hauv nws cov khoom vaj tse. Vim tias qhov tseem ceeb sib txawv ntawm qhov xwm txheej, daim ntawv xaj yuav tsum hais tias lub raj yog kub tiav, kos txias lossis kho cua sov.
Q: Qhov luaj li cas muaj nyob hauv qib 1330 tubing?
Seamless tubing yog tsim nyob rau hauv ib tug ntau yam ntawm sab nraud diameters thiab phab ntsa thicknesses, nrog rau qhov ntev kam rau ua raws li ASTM A519 rooj. Tsis yog- qhov loj me tuaj yeem sib tham txog cov cuab yeej muaj thiab txiav txim kom muaj nuj nqis.
