ASTM A519 Qib 1012 Tubing yog dab tsi
ASTM A519 yog tus qauv specification npog seamless thiab txias welded welded carbon thiab alloy steel mechanical tubing ua rau cov neeg kho tshuab, cov qauv thiab kev pabcuam siab es tsis yog rau kab yeeb nkab ua haujlwm. Qib 1012 zaum ntawm qhov qis - carbon, unalloyed kawg ntawm qib qib suav nrog hauv cov lus qhia. Nrog rau qhov nominal carbon ntau ntawm 0.10-0.15% thiab manganese ntawm 0.30-0.60%, nws sib raug zoo rau 10 # carbon steel uas tsim los ntawm Suav mills, uas yog vim li cas 1012 tubing yog dav xaiv rau kev ua hauj lwm engineering qhov nruab nrab lub zog, zoo formability thiab txhim khu kev qha weldability teeb meem ntau tshaj li siab load peev.
Nyob rau hauv lub annealed los yog normalized mob cov khoom yog mos thiab ductile, yog li nws yog ib txwm muab los ntawm kub tiav los yog txias drawn. Kev kos duab txias txhim kho qhov tseeb qhov tseeb thiab qhov chaw tiav thaum ua haujlwm tawv tawv ntawm phab ntsa, yog li ib qib tuaj yeem xa mus thoob plaws ntau theem ntawm lub zog yooj yim los ntawm kev hloov pauv qhov txias txo thiab ua tiav.

ASTM A519 tsis tau tshaj tawm ib qho ntawm cov khoom muaj nqis rau ib qib. Qhov tsawg kawg nkaus tensile lub zog, qhov tsawg kawg nkaus lub zog thiab qhov tsawg kawg nkaus elongation yog tabulated nyias rau txhua qib thiab rau txhua tus me nyuam, yog li 1012 raj muab kub tiav, txias drawn, los yog txias drawn thiab kev nyuaj siab yog sib txawv yam tsawg kawg nkaus. Txoj hauv kev kom meej meej qhia cov khoom yog hais txog qib ua ke nrog kev xa khoom thiab, qhov twg lub luag haujlwm hnyav, kom pom zoo rau qhov ntsuas tensile ntawm lub raj tiav.
Qhov ntau thiab tsawg, Tolerances thiab kev xa khoom
Qib 1012 txhua yam tubing yog feem ntau tsim nrog sab nraud diameters los ntawm 3.2 hli mus txog 304.8 hli, nrog phab ntsa thicknesses los ntawm lub teeb lub sij hawm mus txog rau cov phab ntsa hnyav, thiab nruab nrab qhov ntau thiab tsawg tuaj yeem muab tau thaum muaj cuab yeej siv. Phab ntsa kam rau ua, ncaj, ovality thiab ntev kam rau ua raws li cov ntxhuav ntawm ASTM A519, thiab txias drawn tubing yog ib txwm txiav txim kom nruj tolerances dua kub tiav tubing. Hydrostatic los yog eddy kev kuaj tam sim no tuaj yeem txheeb xyuas qhov twg lub raj muaj lub siab - muaj nuj nqi.
Tej kev siv
Hydraulic thiab pneumatic lub tog raj kheej chim, piston pas nrig thiab lub tes tsho
Shafting, bushings thiab bearing vaj tse nyob rau hauv dav machinery
Automotive thiab maus taus Cheebtsam xws li spacers, raj thiab brackets
Fittings, couplings thiab qis - cov kab hloov pauv kua dej
Ncej, tso saib cov qauv thiab dav fabricated los ua ke
Fabrication thiab Corrosion Protection
Cov ntsiab lus carbon tsawg muab 1012 zoo heev bendability, flaring thiab swaging tus cwj pwm thiab ua rau nws ncaj nraim rau vuam los ntawm cov pa arc, TIG thiab cov txheej txheem kuj. Preheat feem ntau tsis tsim nyog rau cov phab ntsa nyias thiab nruab nrab, txawm hais tias cov ntu hnyav tau txais txiaj ntsig los ntawm kev ua kom qis qis kom tsis txhob txias sai. Vim tias cov hlau tsis sib xyaw nws tsis muaj qhov cuam tshuam ntawm huab cua tsis zoo, yog li kev tiv thaiv sab nraud feem ntau siv: kub dip galvanizing rau sab nraum zoov cov qauv, phosphating los yog dub oxide luv luv - lub sij hawm tiv thaiv thiab txhim kho cov tsos, thiab epoxy- hom txheej rau tshuaj lom neeg los yog dej hiav txwv ib puag ncig.
FAQ
Q: ASTM A519 qib 1012 tubing siv rau dab tsi?
Nws yog siv rau cov khoom siv hluav taws xob ntau dua li cov kab xa dej: lub tog raj kheej, shafting, bushings, spacer tubes, couplings thiab dav fabricated qhov chaw uas nruab nrab lub zog thiab zoo formability txaus.
Q: Puas yog qib 1012 zoo ib yam li AISI 1012?
Lub npe 1012 piav qhia txog steel chemistry. ASTM A519 yog cov khoom specification uas ntxiv qhov yuav tsum tau rau qhov ntev, kam rau ua, mechanical zog thiab kev soj ntsuam ntawm lub tiav tube, yog li A519 1012 txheeb xyuas ob qib thiab cov tubular khoom daim ntawv.
Q: Yam khoom twg muaj rau 1012 tubing?
Cov xwm txheej ib txwm yog kub tiav, txias rub, thiab txias rub tawm tom qab ntawd kev ntxhov siab los yog annealed. Txhua qhov xwm txheej muaj nws tus kheej yam khoom siv yam tsawg kawg nkaus hauv ASTM A519 cov lus, yog li cov xwm txheej yuav tsum tau teev nyob rau hauv qhov kev txiav txim.
Q: Can 1012 tubing yuav welded?
Yog lawm. Cov pa roj carbon tsawg thiab cov ntsiab lus tsis tshua muaj manganese muab zoo weldability nrog arc, TIG thiab tsis kam vuam. Rau cov phab ntsa hnyav dua qhov preheat ntawm kwv yees li 100-150℃feem ntau yog siv los txwv cov cua txias, thiab cov welds yuav tsum tau ua nrog cov khoom siv huv, qhuav.
Q: Yuav ua li cas 1012 tubing tiv thaiv corrosion?
Vim nws yog cov pa roj carbon steel, kev tiv thaiv nyob ntawm ib puag ncig. Kub dip galvanizing haum rau cov qauv sab nraum zoov, phosphating lossis blackening suits sab hauv tsev uas xav tau luv luv - lub sij hawm tiv thaiv, thiab cov organic coatings yog siv rau cov tshuaj lom neeg los yog dej hiav txwv.
Q: Qhov luaj li cas tuaj yeem muab tau hauv qib 1012?
Sab nraud txoj kab uas hla los ntawm kwv yees li 3.2 hli mus rau 304.8 hli yog niaj hnub tsim, nrog cov phab ntsa los ntawm lub teeb teem sij hawm mus rau phab ntsa hnyav. Tsis yog - tus qauv nruab nrab qhov ntau thiab tsawg tuaj yeem raug hais tawm tsam cov cuab yeej muaj thiab qhov kev txiav txim yam tsawg kawg nkaus.
