ASTM A588, A242 And A709-50W Corten Steel Plates

ASTM A588, A242 and A709-50W Corten Steel Plate ASTM A588 ASTM A588 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars.

ASTM A588

ASTM A588 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance for structural steel shapes such as angles, channel and beams, as well as steel plate and bars. The A588 specification is intended primarily for use in welded bridges and other structures where savings in weight or added durability is important along with the longer life cycle due to its corrosion resistant properties.

The atmospheric corrosion resistance of A588 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. When properly designed and exposed to the atmosphere, A588 is suitable for many applications in the unpainted condition.

ASTM A588 has a 50ksi minimum yield strength and a 70ksi minimum tensile strength.

ASTM A242

ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance. This specification is normally applicable to steel plates through one-half inch in thickness.
The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. When properly exposed to the atmosphere, A242 is suitable for many applications in the unpainted condition.

ASTM A242 has a 50ksi minimum yield strength and a 70ksi minimum tensile strength.

ASTM A709-50W

ASTM A709-50W is a standard specification for structural steel in bridges. ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition.

ASTM A709-50W shall have an atmospheric corrosion index of 6.00 or higher. When properly designed and exposed to the atmosphere, A709-50W is suitable for many applications in the bare unpainted condition.
