ASTM A516 vs A36, A572, Q355: Ke koho ʻana i ka papa kila kūpono no ke kūkulu ʻana i kēia wā

Hāʻawi ʻo ASTM A516 (Nā Papa 60-70) i ​​ka ikaika hua o 260–290 MPa a me ka ikaika tensile a hiki i 550 MPa, i hui pū ʻia me ka paʻakikī haʻahaʻa haʻahaʻa a hiki i -45°C. I ka hoʻohālikelike ʻana:

ASTM A36– Ikaika hāʻawi 250 MPa, tensile 400–550 MPa, hana maʻamau o ka mahana haʻahaʻa.

ASTM A572 (Gr.50)– Hāʻawi 345 MPa, tensile 450–620 MPa, weldability maikaʻi loa a me ka paʻakikī haʻahaʻa haʻahaʻa.

Q355– Hāʻawi 355 MPa, tensile 470–630 MPa, hoʻohana nui ʻia i nā papahana kūkulu Kina no kona ikaika kiʻekiʻe a me ke kūpaʻa.

ʻO kēia ka mea e kūpono ai ʻo A516 no nā kaola ukana kaumaha, nā papa hopena o ke alahaka, a me nā ʻāpana kūkulu i nā wahi anuanu.
