Commentary:The data given in Table 8-4 for A36 and A572 Grade 50 is somewhat weighted by the lighter, Group 1 shapes that will not ordinarily be used in WSMF applications. Excluding Group 1 shapes and combining the Dual Grade and A572 Grade 50 data results in a mean yield strength of 48 ksi for A36 and 57 ksi for A572 Grade 50 steel.

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.

A285 GR C:This grade offers moderate strength characteristics along with the ability for good forming. It is used in fusion-welded boilers and pressure vessels. A515 GR 70:Plate made from this grade of steel offers improved strength compared to A285 steel. The plate incorporates ELEVATED TEMPERATURE PROPERTIES OF A588 is made between A588 weathering steel, used widely for bridges, and another material whose chemical composition and mechanical properties allows it to be classified by ASTM as both an older weathering steel (A242), a steel commonly used in building construction (A992), and also a non-weathering steel used for bridges (A709 Grade 50).

The comparison of Cor-Ten to the ASTM grades is loosely stated as Cor-Ten A is equivalent to ASTM A242 and Cor-Ten B is equivalent to ASTM A588 Grade A. Cor-Ten A and B both meet and/or exceed the requirements of ASTM A606 Type 4.
