Principal Design Features
|
|
This ASTM specification covers carbon steel, cold formed welded and seamless structural tube in both round and shaped forms.
|
|
|
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.
|
|
|
Machinability
|
|
This is a simple carbon steel alloy and is readily machined by conventional means. It is similar to 1027 steel in machining characteristics.
|
|
|
Forming
|
|
Forming is readily accomplished by conventional methods.
|
|
|
Welding
|
|
The alloy is weldable by all of the standard methods.
|
|
|
Heat Treatment
|
|
Not applicable. The product is used in the "as supplied" condition and may be annealed or stress relieved by the supplier as supplied.
|
|
|
Forging
|
|
Product is supplied in piping form and is not subsequently forged.
|
|
|
Hot Working
|
|
No data. Generally hot forming would not be done. Contact the steel supplier for additional information.
|
|
|
Cold Working
|
|
Cold works readily by conventional methods.
|
|
|
Annealing
|
|
May be annealed if necessary at 1600 f and slow furnace cooled. Note that this is usually not feasible for field erected structures.
|
|
|
Tempering
|
|
Not applicable.
|
|
|
Hardening
|
|
Hardens from cold working, although this steel will also harden by heat treatment and quenching such condition is not covered by this specification.
|
|
|
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.
