ASME SA573 Grade 65 plates covered by this specification are limited to a maximum thickness of 1.5 in. [40 mm]. ASME SA573 Grade 65 [450] carbon steel sheets are mainly used for service at atmosheri temperatures where improved notch toughness is import.
ASME SA573 specification covers structural quality carbon-manganese-silicon steel plates in three tensile strength ranges intended primarily for service at atmospheric temperatures where improved notch toughness is important.
