Q235B thiab A36 feem ntau yog siv cov qauv hlau hauv Suav teb thiab Asmeskas, feem. Thaum lawv tuaj yeem hloov pauv hauv qee qhov xwm txheej, qhov sib txawv tseem ceeb hauv qab no yuav tsum tau txiav txim siab:
1. Kev sib xyaw tshuaj sib txawv
Cov ntsiab lus carbon:
A36: 0.25% - 0.28% (lub zog me ntsis tab sis qis dua weldability).
Q235B0.12% - 0.20% (zoo dua weldability).
Manganese Cov ntsiab lus:
A36: 0.8% - 1.2% (ntau zog ntxiv zog).
Q235B: 0.3%–0.7%.
Cov ntsiab lus tsis zoo:
A36: Cov kev txwv nruj dua rau phosphorus (P Tsawg dua lossis sib npaug li 0.04%) thiab sulfur (S Tsawg dua lossis sib npaug li 0.05%).
Q235B: Cov txwv sulfur thiab phosphorus tsawg dua lossis sib npaug li 0.045%.
2. Mechanical Performance Comparison
Yield zog:
A36Ua haujlwm siab: 250 MPa.
Q235BUa haujlwm siab: 235 MPa.
Tensile zog:
A36Ua haujlwm siab: 400-550 MPa.
Q235BUa haujlwm siab: 375-500 MPa.
Elongation: Ob qho tib si ntau dua lossis sib npaug li 20%, nrog cov tawv zoo sib xws.
3. Daim ntawv thov xwm txheej hloov pauv
Haum rau Hloov:
Tsis yog- thauj khoom- cov qauv kabmob hauv qhov kub thiab txias.
General welded Cheebtsam uas tsis muaj lub zog nruj.
Tsis haum rau kev hloov pauv:
Cov haujlwm uas yuav tsum tau ua raws li US cov qauv (xws li ASTM).
Tsawg- qhov kub thiab txias ib puag ncig lossis siab - cov qauv riveted precision.
4. Kev txiav txim siab ntxiv
Cov qauv:
A36: Ua raws liASTMcov qauv.
Q235B: Ua raws li SuavGB/T 700txheem.
Fabrication:
Ob leeg muaj qhov zoo sib xws weldability, tab sisA36Tej zaum yuav tsum tau kho cov txheej txheem vuam vim nws cov ntsiab lus carbon ntau dua.
