Q235 Q235A Q235B H Profile Steel
Q235A, Q235B, Q235C, Q235D yog qhov sib txawv ntawm cov qib. Qhov lawv sawv cev yog qhov feem ntau yog qhov cuam tshuam qhov kub thiab txias sib txawv. Qhov sib txawv ntawm A, B, C thiab D yog hais txog qhov sib txawv ntawm qhov kub thiab txias hauv lawv qhov kev ua tau zoo.
Lawv yog: Q235A qib, tsis muaj kev cuam tshuam; Q235B qib, 20℃ib txwm kub cuam tshuam; Q235C qib, 0℃cuam tshuam; Q235D qib, -20℃cuam tshuam. Ntawm qhov sib txawv qhov kub thiab txias, qhov cuam tshuam qhov tseem ceeb kuj txawv. Hais txog cov khoom siv kho tshuab, Qib A tsuas yog lav cov pa tensile lub zog, tawm lub zog thiab elongation; Qib B pib ntxiv 180℃txias dabtsi yog khoov thiab chav tsev kub cuam tshuam lub zog, Qib C lav 0℃cuam tshuam lub zog, thiab Qib D lav -20℃cuam tshuam lub zog. , tus nqi qis tshaj yog 27J.

Lub teeb yuag: Ib qho ntawm qhov zoo tshaj plaws ntawm txhuas raj yog lawv lub teeb yuag. Aluminum has a low density, making it significantly lighter than other metals such as steel. Cov yam ntxwv no ua rau txhuas raj zoo tagnrho rau cov ntawv thov uas txo qhov hnyav yog qhov tseem ceeb, xws li hauv aerospace, tsheb, thiab kev lag luam tsheb thauj mus los. Qhov hnyav txo kuj ua kom yooj yim tuav, kev teeb tsa, thiab kev thauj mus los ntawm txhuas raj -raws li tshuab.
Corrosion Resistance: Aluminium muaj qhov muaj zog tiv thaiv corrosion. Thaum raug cov huab cua, aluminium tsim ib txheej nyias oxide uas tiv thaiv cov hlau hauv qab los ntawm corrosion. Qhov kev tiv thaiv corrosion no ua rau cov raj txhuas tsim nyog rau ntau yam kev siv, suav nrog thaj chaw marine, cov qauv sab nraum zoov, thiab cov chaw ua tshuaj lom neeg.
