Hot Rolled Plate
ASTM A-36 Hot Rolled Plate
A-36 is a structural quality carbon steel used for use in a variety of general construction applications including; bolted, riveted, or welded construction of bridges and buildings. Minimum yield point is engineered at 36,000 psi. In addition to greater strength than A-283, A-36 plates can be used to design structures and equipment lighter in weight with better weldability.

C1020 Hot Rolled Plate
The higher carbon range of C1020 improves the machinability of thisgrade. Good formability and weldability are also characteristic.

Hot Rolled Plate
C1045 Hot Rolled Plate
C1045 is silicon killed with a higher carbon content for greater strength. Strength can be improved in the lighter and medium thicknesses by heat treatment. Machinability is good, while forming and welding properties are limited.

C1008/1010 HRCQ
ASTM A-569
Hot rolled commercial quality steel is suitable for many applications where normal surface imperfections are not objectionable. Heat treatment and other processing operations must be properly performed so as to not detrimentally affect the properties of the steel. Commercial quality will meet the bend test requirements of ASTM A569.
