ASTM B152 / B152M-19 Txuj kev qhia tshwj xeeb rau daim ntawv tooj liab, sawb, phaj, thiab dov bar

Cov qauv no suav nrog cov ntawv yuav tsum tau ua rau daim ntawv tooj liab, sawb, phaj, thiab dov bar ua los ntawm tooj liab nrog rau UNS Nos .; C10100, C10200, C10300, C10400, C10500, C10700, C10800, C10910, C11000, C11300, C11400, C11600, C12000, C12200, C11200, C14420 thiab C14530. Cov tshuaj muaj pes tsawg leeg yuav tsum ua raws li cov kev cai tshuaj uas hais txog cov ntaub ntawv UNS No. Tempering ntawm cov ntaub ntawv yuav tsum tau ua los ntawm kub- dov, txias dov, thiab annealing. Cov khoom siv tooj liab yuav tsum ua kom tau raws li qhov siab tshaj plaws ntawm cov hluav taws xob tiv thaiv raws li qhia. Cov khoom siv yuav tsum tau txais lub zog tensile, Rockwell hardness, thiab cov khoom siv phaj kuaj kom ua raws li qhov yuav tsum tau ua ntawm cov cuab yeej cuab tam ntawm cov lus qhia. Cov khoom siv kuj tseem muaj peev xwm dhau qhov kev kuaj xyuas microscopical thiab embrittlement test, tab sis tsis tas yuav tsum tau ua los ntawm qhov tshwj xeeb.

1.1 Qhov kev qhia tshwj xeeb2 no tsim cov kev cai rau daim ntawv tooj liab, sawb, phaj, thiab dov bar ua los ntawm cov tooj liab hauv qab no.

Lus Cim 1: Txhua tus tooj liab tau teev tseg muaj cov khoom tshwj xeeb uas tuaj yeem ua rau nws haum rau cov ntawv thov tshwj xeeb. Tus neeg yuav khoom yuav tsum sab laj nrog tus neeg muag khoom los txiav txim siab seb tooj liab twg yuav zoo tshaj plaws rau daim ntawv thov.

Faj seeb 2: Qhov kev qhia tshwj xeeb no tsis yog tsim los tsim kom muaj cov khoom siv dov rau ounce - hnyav thicknesses. Cov khoom siv no tau txhais hauv Specification B370.

Pav ca tooj liab cov khoom uas tiav lawm (dov los yog kos) npoo (flat hlau thiab sawb) yog txhais nyob rau hauv Specification B272.

1.1.1 Thaum tsis muaj ib qho tooj liab tshwj xeeb hauv daim ntawv cog lus lossis kev yuav khoom, tus neeg muag khoom tuaj yeem muab cov khoom los ntawm ib qho ntawm cov tooj liab uas tau teev tseg.

1.2 Chav nyob-Cov nqi teev nyob rau hauv ib nti - phaus units los yog SI units yuav tsum tau muab cais raws li tus qauv. Cov txiaj ntsig tau teev tseg hauv txhua qhov system tsis tas yuav muaj qhov sib npaug; Yog li ntawd, txhawm rau kom ua tau raws li tus qauv, txhua qhov system yuav tsum siv nws tus kheej ntawm lwm tus thiab cov txiaj ntsig los ntawm ob lub tshuab yuav tsum tsis txhob sib xyaw.

1.3 Cov kev tiv thaiv kev nyab xeeb hauv qab no tsuas yog cuam tshuam rau txoj kev sim (cov) uas tau piav qhia hauv qhov tshwj xeeb no:

1.3.1 Tus qauv no tsis hais txog txhua yam kev txhawj xeeb txog kev nyab xeeb, yog tias muaj, cuam tshuam nrog nws txoj kev siv. Nws yog lub luag haujlwm ntawm tus neeg siv ntawm tus qauv no txhawm rau tsim kom muaj kev nyab xeeb, kev noj qab haus huv, thiab kev coj ua ib puag ncig thiab txiav txim siab txog kev siv cov kev txwv kev txwv ua ntej siv.

1.4 Cov txheej txheem thoob ntiaj teb no tau tsim los ua raws li cov txheej txheem thoob ntiaj teb lees paub txog kev tsim qauv tsim hauv Kev Txiav Txim Siab ntawm Cov Ntsiab Cai rau Kev Txhim Kho Cov Txheej Txheem Thoob Ntiaj Teb, Cov Lus Qhia thiab Cov Lus Pom Zoo los ntawm World Trade Organization Technical Barriers to Trade (TBT) Committee.

vim li cas xaiv peb

 

vim li cas xaiv peb cov khoom

 

Peb yog cov chaw tsim khoom lag luam thiab xa tawm tshwj xeeb hauv kev ua tiav ntau yam ntawm - cov khoom siv tooj liab zoo, suav nrog cov raj tooj liab, tooj liab / daim ntawv, tooj liab tuav, tooj liab rods, tooj liab xov hlau, thiab tooj liab strips. Peb cov chaw tsim khoom siab heev tau nruab nrog lub xeev - ntawm - - kos duab nruam casting kab, extrusion presses, txias dov mills, thiab kos duab tshuab kom paub meej thiab sib xws. Kev tswj xyuas kom zoo yog qhov tseem ceeb rau peb cov txheej txheem, ua los ntawm spectrometers rau cov khoom pov thawj, tensile testers, eddy tam sim no testers, thiab hydrostatic siab testers, lav tias tag nrho peb cov khoom ua tau raws li cov qauv thoob ntiaj teb rau kev ua tau zoo thiab kav ntev.
