Qhov txawv tseem ceeb:
Carbon Content: A516 Gr 55 has a slightly higher maximum carbon content for thicker plates (>50mm), thaum A516 Gr 70 tswj qhov sib npaug 0.27% max hla txhua qhov tuab.
Manganese Range: A516 Gr 55 muaj ntau yam manganese dav (0.79-1.30%), thaum A516 Gr 70 muaj qhov nqaim (0.85-1.20%), ua rau nws muaj zog dua.
Cov pa roj carbon sib npaug (Ceq): Ob qib siv cov qauv Ceq=[C + Mn/6 + (Cr+ Mo+V)/5 + (Ni+Cu)/15] los xyuas kom meej weldability. A516 Gr 70's tighter muaj pes tsawg leeg txhim kho nws lub zog yam tsis muaj kev cuam tshuam weldability.

Qhov txawv tseem ceeb:
Yield Strength: A516 Gr 70 muaj qhov siab dua qhov siab tshaj tawm lub zog (260 MPa) piv rau A516 Gr 55 (205 MPa), ua rau nws tsim nyog rau siab dua - kev siv siab.
Tensile Strength: A516 Gr 70 muaj lub zog tensile ntau dua (485-620 MPa) dua li A516 Gr 55 (380-515 MPa), muab kev ua haujlwm ntev dua hauv qhov xav tau ib puag ncig.
Elongation: A516 Gr 55 muaj elongation ntau dua (txog 27%) piv rau A516 Gr 70 (txog 21%), qhia tau hais tias zoo dua ductility rau kev tsim cov txheej txheem.
Impact Toughness: Ob qib txhawb kev xaiv Charpy V- ntsuas ntsuas ntsuas (piv txwv li, -20℃lossis -46 degree) raws li cov neeg siv khoom tshwj xeeb, kom ntseeg tau tias kev ua haujlwm kub qis.
