Hot Rolled Bars

ASTM A36 A mild steel for general purpose applications. Excellent for mild cold and hot forming, very suitable for general usage in production and maintenance work, and easily welds. Good material for machining, drilling, tapping, punching and grinding. Suitable for applications that do not require the greater strength oh high carbon or alloy steels. The very thin rectangles are generally sold as strip, and size selection is not as great as cold roll C1018. Larger diameters in ASTM A36 are not generally produced, as C1018 hot roll rounds are usually used.

APPLICATIONS

ASTM A36 is used for general purpose structural, machinery parts, frames, fixtures, automotive and agricultural implements and equipment, brackets, stakes, ornamental works, forgings, base plates, and miscellaneous \non-critical applications that involve mild cold bending, mild hot forming, punching, machining, and welding

MACHINEABILITY AND WELDABILITY

ASTM A36 has a machinability rating of 72%, based on 1212 at 100%. Average surface cutting feed 120 ft/min.
ASTM A36 is easily welded by all welding processes and the welds and joints produced are of extremely high quality.

HEAT TREATING

ASTM A36 is generally not heat treated but is typically stress relieved prior to grinding or machining or after welding and prior to machining. ASTM A-36 can be carburized, however, for a higher surface hardness.
Stress Relieve 1100°-1250°F. Typical Stress relieve soak time
one hour per inch of thickness.
Carburize 1650°-1700° F.
