A515 Qib 65 yog rau nruab nrab- mus rau- cov hlab ntsha kub siab, tsom rau lub zog ntawm cov cua sov, thaum A516 Qib 65 yog rau nruab nrab- rau- qhov kev pab cuam kub qis, ua qhov tseem ceeb tshaj qhov tsis sib haum xeeb (kev cuam tshuam tsis zoo) ntawm qhov txias dua, txawm tias ob qho tib si sib piv lub zog sib xws ~ 20 min. tensile ~ 450-585 MPa). Qhov sib txawv tseem ceeb yog daim ntawv thov: A515 rau cua sov, A516 rau txias / cuam tshuam.

ASTM A515 Qib 65
Kev Siv Tseem Ceeb: Nruab nrab mus rau qhov kub siab dua cov hlab ntsha.
Cov ntsiab lus tseem ceeb: Cov ntsiab lus carbon ntau dua (nyob ib puag ncig 0.28-0.33%) muab nws lub zog kub zoo dua.
Kev ua tau zoo: Muaj zog thiab ruaj khov dua ntawm qhov kub siab.
ASTM A516 Qib 65
Kev Siv Tseem Ceeb: Nruab nrab mus rau qhov kub siab ntawm cov hlab ntsha, nrog rau qhov tseem ceeb ntawm toughness.
Cov yam ntxwv tseem ceeb: Optimized rau zoo dua thais toughness (lub zog cuam tshuam) nyob rau hauv txias txias.
Kev ua tau zoo: weldability zoo heev thiab kev ua tau zoo hauv sub- xoom mus rau nruab nrab kub.
Cov yam ntxwv tseem ceeb (qib 65 tshwj xeeb)
Tawm Zog: Tsawg kawg 240 MPa (35 ksi).
Tensile zog: 450-585 MPa (65-85 ksi).
Daim ntawv thov: Ob leeg siv nyob rau hauv welded boilers & siab hlab ntsha.
Hauv cov ntsiab lus yooj yim:
Xaiv A515 Gr. 65 yog tias koj lub nkoj khiav kub; xaiv A516 Gr. 65 yog tias nws khiav txias thiab yuav tsum tiv thaiv kev tawg los ntawm kev cuam tshuam.
