ASTM A36, ASTM A572, ASTM A656, JIS G3101 SS400, EN10025-2, DIN 17100, DIN 17102, GB/T700, GB/T1591
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.
A283 steel plate is a low-to-intermediate tensile strength carbon steel used for general structural purposes, particularly in building storage tanks, low-pressure vessels, bridges, and other general fabrication where good weldability and formability are needed, standardized by ASTM. It comes in grades (A, B, C, D) with varying strength levels, with Grade C being common, similar to mild steels like ASTM A36, and offering good properties for construction.
