ASTM A283 plate steel features low and intermediate tensile strength carbon steel plate of structural quality. It has four common variants, each represented as a separate material. The material properties section below shows ranges encompassing all variants.

This specification covers four grades of carbon steel plates of structural quality for general application. Steel samples shall be melt processed by either open-hearth, basic-oxygen, or electric furnace. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, and copper. Steel specimens shall also undergo tensile tests and shall conform to required values of tensile strength, yield point, and elongation.

Comparison between A36 and A283C

1, ASTM A 283 Gr C consist of four grade of material (A,B,C, & D) of carbon steel plate of structural quality for general application.
2, ASTM A 36 covers carbon steel plate, shape, and bar of structural quality for use in riveted, bolted or welded construction of bridges and building and for general structural purpose.
3, From material scope, both ASTM A 36 and ASTM A 283 are the carbon steel of structural quality for general application.
