Cov qauv hauv teb chaws rau cov ntawv txias-dov hlau feem ntau suav nrog "National Standards of the People's Republic of China: Dimensions, Shape, Weight, and Allowable Deviation of Cold Rolled Steel Phaj thiab Strips (GB/T708-2006)" thiab "Cold Rolled Thin Steel Phaj thiab Sawb rau Carbon Structural Steel (GB/T 13237-1991)". Cov qauv no muab cov ncauj lus kom ntxaws txog qhov ntev, cov duab, qhov hnyav, qhov sib txawv ntawm qhov kev tso cai, thiab cov khoom siv hluav taws xob ntawm cov ntawv txias-dov hlau.
Tshwj xeeb, "National Standard of the People's Republic of China: Dimensions, Shape, Weight, and Allowable Deviations of Cold Rolled Steel Phaj and Strips (GB/T708-2006)" feem ntau yog siv rau cov khaub thuas dov steel strips thiab lawv. shear khoom. Nws tau rov txhais qhov kev faib tawm thiab cov lej, ntxiv cov lus pom zoo nominal thicknesses rau steel daim hlau thiab strips, thiab rov txhais cov kev sib txawv uas tso cai rau thickness, dav, ntev, tsis sib xws, skew, thiab mob dabtsi yog khoov.
Cov "Cold Rolled Thin Steel Phaj thiab Strips ntawm Carbon Structural Steel (GB/T 13237-1991)" roughly faib txias-dov nyias steel phaj rau peb theem, xws li P qib rau zoo tib yam stamping, S qib rau sib sib zog nqus stamping, thiab Z qib rau sib sib zog nqus stamping. Tsis tas li ntawd, Suav metallurgical standard YB/T 5059-1993 "Cold Rolled Steel Strips of Low Carbon Steel" faib cov phaj nyias nyias ua tsib qib raws li qhov nyuaj, suav nrog qib tshwj xeeb, mos, ib nrab mos, tsis tshua muaj zog, thiab txias. nyuaj.
Tsis tas li ntawd, muaj qee cov qauv rau cov ntawv txias-dov stainless hlau, xws li "Cold Rolled Stainless Steel Phaj" tus qauv (GB/T 3280-1992), uas qhia txog qhov ntev, cov duab, qhov hnyav, thiab qhov sib txawv ntawm qhov kev tso cai. txias dov stainless hlau phaj.
Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv ntxiv, cov qauv zoo rau cov khaub thuas dov coils tau muab faib ua lub hom phiaj dav dav thiab lub hom phiaj tshwj xeeb raws li lawv siv, thiab ua rau lub teeb ci ci, iav coil, thiab tsis yog taw qhia kauj raws li lawv qhov chaw. Cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm ntawm lub cev kuj tseem nruj heev, suav nrog cov ntsiab lus tshwj xeeb xws li carbon, silicon, manganese, phosphorus, thiab sulfur, nrog rau ntau yam qauv xws li tensile zog, taw tes tawm, thiab elongation.
