ASTM A203 Steel plate

 

 

 

 

A203 standard specification is for pressure vessel plates, alloy steel in nickel. This steel grade covers nickel-alloy steel plates intended primarily for welded pressure vessels.

 

A203 steel plates under this specification are available with four strength levels and two nickel compositions in 2.25% and 3.5%

 

The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. However, current practice normally limits the maximum thickness of plates furnished under this specification as follows:

 

Grade            Maximum Thickness, in. [mm]

A203 Grade A          6 [150]

A203 Grade B          6 [150]

A203 Grade D          4 [100]

A203 Grade E          4 [100]

A203 Grade F          4 [100]

 

In Heat Treatment

 

All plates of Grades A, B, D, and E shall be normalized  If approved by the purchaser for Grades A, B, D, and E, cooling rates faster than air cooling are permissible for improvement of the toughness, provided the plates are subsequently tempered at not less than 1100°F [595°C] for not less than 1⁄2 h.

 

All plates of Grade F shall be heat treated by heating into the austenitic range, quenching in water, and tempering at not less than 1100°F [595°C] for not less than 1⁄2 h.
