Hardens due to cold working or aging heat treatment — see “Aging”. This abstract is a brief summary of the referenced standard. Welding by all of the standard processes may be done, including gas torch welding.
Forming characteristics are good by conventional processes. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Tensile properties of the specimens such as tensile and yield strengths and bending shall be determined by tension test and bending test, respectively. A stress relief anneal g317 cold working may be done at F with air cooling.
Shear strength values are: Type A material, last covered in the issue of this specification, is no longer available; therefore, requirements for cold-finished rectangular bar have been deleted.
The values stated in each system may not be exact equivalents; therefore each system shall be used g317 of the other.
Hot working generally is not required because the alloy has very good cold working characteristics. T61 – 17 ksi.
Aluminum T61 Extruded Round Pipe Schedule 40 ASTM B – SarahFlynnTSIt
wstm The preferred method of welding is by means of inert gas arc welding for best results. This specification covers aluminum-alloy extruded bar, rod, tube, pipe, Schedules 40 and 80structural profiles, and profiles in selected tempers for use as electric conductors.
The bars, rods, tubes, pipes, structural profiles and profiles shall be produced by hot extrusion or by similar methods. Historical Version s – view previous versions of standard.
T61 F for astn hours and air cool. T6 F for 20 hours and air cool. No data, although the alloy is considered forgeable. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. When welded in the heat treated condition the subsequent parts will be lower in strength because of weld heat input.
ASTM B317/B317M – 07(2015)E1
It is hardened strengthened by heat treatment. Use of an oil base lubricant during machining operations is recommended. T6 – 22 ksi. This is a high electrical conductivity aluminum alloy also possessing good mechanical strength properties. Annealing is done at F for 3 hours at temperature, followed by controlled cooling at a rate of 50 F per hour down to F, then air cool.
Combining values from the two systems may result in non-conformance with the standard. T63 F for 19 hours and air cool. Machinability by conventional means is good. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 7 distributors but is also available to a lesser extent in Tubular Products.
Aging is done at different temperatures and times, depending upon the finished temper desired as follows: Easily cold worked, or cold formed in either the annealed or aged conditions.
Electrical resistivity and conductivity shall b137 determined. The AL alloy does respond to heat treatment which is accomplished by annealing and relatively low temperature aging. Filler rod of the same alloy should be used. Either carbide or high speed tool steel tooling may be used.
Electrical bus bar conductor applications for use in enclosed bus electrical installations. See also Cold Working. T63 – 21 ksi. See “Annealing” and “Aging”. Link to Active This link will always route to the current Active version of the standard. Modulus of Elasticity Tension. Pipe or tube may be produced through porthole or bridge type dies.
