Q195 steel phaj qib txhais li cas?
Raws li GB/T 700-2006, "Q" sawv cev rau lub zog tawm los, thiab "195" qhia tias qhov tsawg kawg nkaus lub zog yog 195 MPa rau lub thickness ≤16mm. Nws belongs rau low-carbon carbon structural steel.
Dab tsi yog cov khoom tseem ceeb ntawm Q195 steel phaj rau kev tsim kho?
Cov pa roj carbon tsawg (C: 0.06% -0.12%), siab plasticity, zoo weldability, yooj yim txias ua hauj lwm, kuj tsis tshua muaj zog, thiab cov nqi tseem ceeb.
Dab tsi yog qhov txawv ntawm Q195 thiab Q235 hauv kev tsim kho?
Q195 muaj lub zog qis dua ntawm kwv yees li 40MPa. Q195 tsuas yog tsim nyog rau cov tsis yog-load-cov kabmob lossis cov kabmob theem nrab- cov kabmob, thaum Q235 tuaj yeem siv rau kev thauj khoom dav dav-cov kabmob.
Dab tsi yog cov qauv siv feem ntau ntawm Q195 steel phaj hauv kev tsim kho kev lag luam?
Kub-rolled phaj, txias-rolled phaj, galvanized phaj, thiab xim-coated phaj. Ntawm cov no, txias- dov phaj (0.6-1.2mm) yog siv dav tshaj plaws hauv kev kho kom zoo nkauj teb.
Dab tsi yog cov qauv siv rau Q195 steel phaj?
Khoom siv: GB / T 700-2006; Tus qauv Dimensional: GB / T 912-2008; Galvanized ntawv: GB / T 2518-2019.
