ASTM A240 yog tus qauv siv dav dav rau chromium thiab chromium-nickel stainless hlau phaj, ntawv, thiab sawb siv rau cov hlab ntsha siab thiab rau kev siv dav hauv ntau yam lag luam. Nws npog ntau yam ntawm stainless hlau qib thiab specifications.
Nov yog qee cov ntsiab lus tseem ceeb ntawm ASTM A240:
ScopeASTM A240 npog chromium, chromium-nickel, thiab chromium-manganese-nickel stainless hlau phaj, ntawv, thiab sawb rau cov hlab ntsha siab thiab rau kev siv dav dav. Nws suav nrog cov ntaub ntawv kub-kuav los tiag thiab cov khoom siv txias-dov.
Qib: Cov txheej txheem suav nrog ntau qib stainless hlau, xws li austenitic, ferritic, thiab martensitic stainless hlau. Cov qib feem ntau suav nrog 304/304L, 316/316L, 321, 347, 409, 410, 430, thiab ntau lwm yam.
Tshuaj muaj pes tsawg leegASTM A240 qhia txog cov tshuaj muaj pes tsawg leeg uas yuav tsum tau muaj rau txhua qib ntawm stainless hlau, nrog rau qhov tsawg kawg nkaus thiab siab tshaj cov ntsiab lus ntawm ntau yam xws li chromium, nickel, carbon, manganese, silicon, phosphorus, sulfur, thiab nitrogen.
Mechanical Properties: Cov txheej txheem yuav qhia cov cuab yeej cuab tam xws li lub zog tensile, lub zog tawm los, elongation, thiab hardness rau qee qib thiab tej yam kev mob.
Nto tiav: ASTM A240 kuj tseem yuav suav nrog qhov yuav tsum tau ua kom tiav, xws li smoothness, brightness, thiab flatness, nyob ntawm daim ntawv thov thiab kev tsim khoom.
Daim ntawv thov: Stainless hlau cov khoom tsim los rau ASTM A240 specifications yog dav siv nyob rau hauv ntau yam industries, xws li tshuaj ua, khoom noj khoom haus thiab dej haus, tshuaj, tsheb, kev tsim kho, thiab architecture, vim lawv corrosion kuj, lub zog, thiab zoo nkauj thov.
Hauv cov ntsiab lus, ASTM A240 teeb tsa cov qauv rau kev muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab ua tiav ntawm stainless hlau phaj, ntawv, thiab sawb, ua kom lawv haum rau ntau yam kev siv thoob plaws kev lag luam sib txawv.
