A36 Structural Shapes:

A shape is classified as a "Bar Size Shape" when its greatest dimension (excluding length) is less than three inches. It is a "Structural Shape" when at least one of its dimensions (excluding length) is three inches or greater. These shapes conform to ASTM A36 in its manufacture and mechanical tolerances. HR angle is measured by its legs' dimension on the exterior and by its thickness. HR angle may be equal or unequal dimension (i.e.: 2 x 2 x 1/4" hr angle / 3 x 2 x 1/4" hr angle). In the designation of HR Channels, a letter or letters precedes the size and weight per foot, i.e.: C3 x 4.1# is the AISI designation for a channel 3" wide at its base and 4.1 pounds weight per foot standard structural channel. "C" shapes are channels produced in accordance with dimensional standards adopted in 1896 by the Association of American Steel Manufacturers for American Standard channels. The essential part of these standards is that the inside flange surfaces of American Standard channels have approximately a 16-2/3% slope. "MC" shapes are channels that cannot be classified as "C" shapes.

 

General Information about A36 Structural Steel:


APPLICATIONS:

A36 Structural Steel is used for general structural purposes and in riveted, bolted, or welded construction of buildings, bridges, machinery, etc. It is also used for booms, rails, braces, frames, brackets, cross-members, liners, truck trailers, truck beds, racks, etc.

MACHINING AND WELDING:

It has a machinability rating of 72%, based on 1212 at 100%. Average surface cutting feed is 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 - Forging, Normalizing, and Annealing:

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 is one hour per inch of thickness.

Carburize 1650° - 1700°F.
