ASME SA573 Grade 58 material is a structural quality carbon steel plate. Heat and product analysis shall conform to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, and silicon as follows.
ASME SA573 plates covered by this specification are limited to a maximum thickness of 1.5 in. [40 mm]. ASME SA573 Grade 58  carbon steel plate are mainly used for service at atmosheri temperatures where improved notch toughness is import.
