Steel A500 Grade A

Aging Procedure

Not applicable.

Annealing Procedure

May be annealed if necessary at 1600 f and slow furnace cooled. Note that this is usually not feasible for field erected structures.

Applications

Applications are for structural use as in bridges, buildings or general structural use. The alloy may be welded, bolted or riveted for construction purposes.

Cold Workability

Cold works readily by conventional methods.

Forgeability

Product is supplied in piping form and is not subsequently forged.

Formability

Forming is readily accomplished by conventional methods.

Hardening Procedure

Hardens from cold working, although this steel will also harden by heat treatment and quenching such condition is not covered by this specification.

Heat Treatability

Not applicable. The product is used in the "as supplied" condition and may be annealed or stress relieved by the supplier as supplied.

Hot Workability

No data. Generally hot forming would not be done. Contact the steel supplier for additional information.

Machinability

This is a simple carbon steel alloy and is readily machined by conventional means. It is similar to 1027 steel in machining characteristics.

Other Comments

Grade A is similar to 1027 plain carbon steel in properties. Tensile requirement for Grade A is 45 ksi minimum with 25% elongation.

Principle Design Features

This ASTM specification covers carbon steel, cold formed welded and seamless structural tube in both round and shaped forms.

Tempering Procedure

Not applicable.

Weldability

The alloy is weldable by all of the standard methods.
