Q235 steel yog dab tsi?
A: Q235 yog cov pa roj carbon zoo tib yam steel, feem ntau siv "kev lag luam yooj yim steel," ua raws li lub teb chaws tus qauv GB / T 700-2006.
Cov tsiaj ntawv thiab cov lej hauv qib Q235 txhais li cas?
A: Q=Yield zog (Qu), 235=Yield zog ≥ 235MPa; Suffixes A/B/C/D qhia qib zoo, F=rimmed steel, Z=tua steel (tuaj yeem tshem tawm).
Hom hlau twg yog Q235?
A: Tsawg-carbon steel (C≤0.22%), tsis yog- alloy steel, nrog lub zog tawm los ua qhov taw qhia tseem ceeb.
Dab tsi yog qhov txawv ntawm Q235 thiab Q355?
A: Q235 yog cov pa roj carbon zoo tib yam (235MPa), Q355 yog qis- alloy siab- lub zog steel (355MPa); Q355 muaj zog dua, zoo dua qis -kub toughness, thiab yog 20%-30% kim dua. Qhov txawv ntawm Q235 thiab 35 # steel yog dab tsi?
Teb: Q235 yog qis- carbon structural steel (C≤0.22%), hos 35 # yog nruab nrab-carbon siab- zoo steel (C≈0.35%). Q235 muaj zoo plasticity thiab weldability, thaum 35 # muaj zog dua thiab hardness.
