ASTM B575 phaj Sheet Sawb Chev Tolerance
Kev kam rau siab specifications rauASTM B575 daim hlau, ntawv, strips, thiab coilsNws txawv nyob ntawm tej yam xws li cov khoom thickness, dav, thiab ntev. ASTM B575 npog nickel-chromium-hlau-molybdenum-tooj liab alloys (UNS N06007, N06975, N06985, thiab N06030) thiab nickel-chromium-molybdenum alloys (UNS N10276/Hastelloy C276thiabN06022/Hastelloy C22) nyob rau hauv ntau yam ntaub ntawv, xws li phaj, ntawv, sawb, thiab coil.
ASTM B 575 Cov Lus Qhia Tshwj Xeebqhia txog plaub yam khoom: ntawv, phaj, coil thiab sawb. Ntawm lawv, Phaj yog tsim los ntawm cov txheej txheem kub dov nrog cov phab ntsa tuab. Daim ntawv yog tsuas yog tsim los ntawm cov txheej txheem ntawm txias dov, thiab phab ntsa thickness yog kuj nyias. Sawb kuj yog tsim los ntawm txias dov, tab sis nyob rau hauv qhov dav dav thiab muab nkag rau hauv daim ntawv coil.
Kev kam rau siab rau cov ntaub ntawv tsis ncaj qha rau hauv ASTM B575. Tab sis tus qauv qhia tias qhov kam rau ntawm cov khoom yuav tsum ua raws li ASTM B906.

Sau ntawv
- Qhov ntug curvature (qhov tob ntawm chord) ntawm daim ntawv tiaj tus, sawb, thiab phaj yuav tsum tsis pub tshaj {{0}}.05 in. (1.27 mm) muab qhov ntev ntawm taw lossis 0.04 mm muab qhov ntev hauv cm siab. Ncaj nraim rau coiled sawb yog nyob ntawm kev pom zoo ntawm cov chaw tsim khoom thiab cov neeg yuav khoom.
- Rau cov nplooj ntawv ntawm tag nrho cov thicknesses thiab dav ntawm 6 nyob rau hauv. (152.4 mm) los yog ntau tshaj, lub kaum sab xis ntawm ib sab yuav tsum yog 9 0± 0.15 degree
- Phaj, ntawv, thiab sawb yuav tsum ua lag luam ncaj nraim.
Nruab Nrab Loj Loj
Rau cov nplooj ntawv annealed, tus qauv qhia qhov nruab nrab ntawm qhov loj ntawm cov khoom. Cov nplej loj ntawm cov nplooj ntawv nrog thickness hauv qab 3.175mm yuav tsum tau tswj ntawm ASTM No.3 los yog finer. Cov nplooj ntawv nrog lub thickness ntawm ntau tshaj 3.175mm yuav tsum ncav cuag lub grain loj ntawm ASTM No.1.5 los yog finer.
