Diferans prensipal la se ke ASTM A709 Klas 36 se yon estanda US ak yon fòs sede minimòm de 36,000 psi (36 ksi), pandan y ap Q345q se yon estanda Chinwa ak yon fòs sede minimòm 345 MPa. Tou de se gwo -fòs ki ba-alyaj asye yo itilize pou pon, men yo gen diferan espesifikasyon estanda ak nivo fòs, ak Q345q ki gen yon pi gwo fòs sede minimòm lè konvèti nan menm inite yo.
