Accreditation Administration System:
ASTM A573Gr58 and ASME SA573Gr58 is a kind of structual carbon steel plates of improved toughness which
intended primarily for service at atmospheric temperatures where improved notch toughness is important.
This specification mainly according to A6/A6M which for general requirements for rolled steel plates,shapes,sheet
piling,and bars for structural use.The relative steel grades in this standard as follows :ASTM A573Gr58|A573Gr65|
A573Gr70|ASME SA573Gr58|SA573Gr65|SA573Gr70
The Heat Analysis and tension test specimens both shall conform to the requiements as to the values in the below
table.
