A283GrA Application :
A283GrA steel plate is one mainly of Carbon and low alloy steel, ASTM A 283Â steel covers low and intermediate tensile strength carbon steel plates for general manufacturing and constructional applications.ASTM A283GrA is normally supplied in the rimmed or semi-killed types of steel and is particularly suitable for the economical production of assemblies requiring a considerable amount of forming.
