A312 san pwoblèm asye konpozisyon chimik Tib:
ASTM A312se yon asye ki pa alyaj estriktirèl anba estanda Ewopeyen an, ekivalan a Q235b estanda Chinwa a. Konpozisyon chimik li yo gen ladan yon kontni kabòn (C) nan mwens pase oswa egal a 0. 17%, Silisyòm kontni (SI) nan mwens pase oswa egal a 0. 0. 0 30%, ak kontni souf (yo) nan mwens pase oswa egal a 0.030%.
ASTM A312 san pwoblèm asye Tib Pwopriyete mekanik:
Fòs nan sede se pi gran pase oswa egal a 235 MPa, pandan y ap fòs la rupture chenn ant 360-510 MPA. Elongasyon an pi gran pase oswa egal a 18%, demontre bon severite ak weldability. Li ka kenbe tèt ak yon sèten degre nan deformation san yo pa fraktur.
