ASTM A283 Grade C Low and Intermediate Tensile Strength Carbon Steel Plates
ASTM A283 Class C Specifications:
Thickness: 2mm-650mm
Width: 1000mm-4200mm

From material scope, both ASTM A36 and ASTM A283 are the Carbon Steel of Structural Quality for General Application. It seem that CE of A283 Gr C is higher than A36, Base on this A283 Gr C is little bit difficult to weld compare to A36.
Both A283 Gr C and A36 is groupon to the same P number 1, it mean that once we make the WPS/PQR with A36 it also valid for A283 Gr C. The mechanical properties between A36 and A283 Gr C are almost the same which mean the mechanical properties range are not big different.
Base on the above explanation, it can consider that A36 can be used to alternative substitution of A283 Gr C.
