A-286 is iron-base superalloy useful for applications requiring high strength and corrosion resistance up to 1300°F (704°C) and for lower stress applications at higher temperatures., it is widely used in jet engine components, fasteners and springs that are subjected to temperatures up to 1800ºF, and non-magnetic cryogenic equipment. Exhaust parts, turbines and nozzles utilized in the oil industry require the high tensile strength and good corrosion resistance.
The A-286 forged materials supplied in accordance to this specification shall be produced with the following
processes:
- For A-286 forging parts triple melt material, VIM + ESR + VAR.
- For A286 forged material double melt material, VIM + VAR is acceptable.
For each ingot a sufficient allowance shall be left to ensure absence of sh rinkage cavity or excessive chemical and non -metallic segregation.
The materials supplied according to this specification shall be free from internal and external defects such as to impair the manufacturing and correct operation of the components produced.
The chemical composition of A286 forged material shall be made on samples which correspond to the top & bottom of the re -molten ingot used to the make the part according to ASTM E354, ASTM E1473, ASTM E2465 and ARP1313 for trace elements (lead, bismuth and selenium). Others than abovementioned standards may be used provided THAT they are approved by the purchaser.
Chemical analysis performed on final product shall conform to the variations specified in ASTM B880.
Micrographic characteristics of A286 forged parts
The sampling of metallographic specimens shall be approved by clients.
The optical micrographs shall be taken on polished specimens after etching by Kalling’s reagent at x200 and x500 magnifications.
• Regular microstructure: after the supply heat-treatment, delta phase shall be uniformly distributed with globular and/or rectangular shape;
• Irregular microstructure: the presence of acicular delta phase, stringers/networks of precipitates and sharp edge grains is admitted only if
results of all mechanical properties required by part spec are acceptable
Grain size of A286 forged rings, determined according ASTM E112, shall be as follows:
for turbine use a286 forging parts grain dimension shall be 7 or finer. The maximum size of limited areas, distributed randomly, could be 5.
for other use of a-286 forging parts grain dimension shall be 4 or finer. The maximum size of limited areas, distributed randomly, could be 2.
Transition between zones of different grain size shall be gradual.
In case of inhomogeneous grain size distribution the following information shall be reported:
• average dimension of the two sizes of grain
• % of coarse grain
Individual grains having dimension 2 or finer (ASTM E112) are acceptable if they are surrounded by grain with dimension 7 or finer (necklace structure).

Following is heat treatment way of A-286 forged material
Solution Heat Treatment:
980ºC ± 10 for > 1 hour, followed by air cool (BS)
1800ºF ± 25 (982 ± 14ºC) 1 hour, water/oil quench (AMS)
Precipitation Heat Treatment:

Mechanical properties Tests of A286 forged bars are to be performed according to ASTM E8, ASTM E21, ASTM E10, ASTM E606, ASTM E647, ASTM E399 and ASTM E292.
Any test bar not meeting minimum property requirements shall require re -testing. If the original test bar fails due to a clear special cause (e.g. test machine failure) one re-test is required.
The re -tested bar shall meet minimum property requirements and the result must be reported.
If the original test bar does not meet minimum property requirements and a well-defined cause is not found, then two re -tests are required. All retested bars shall meet the requirements; all test results, including the original one, shall be reported.
Bars for re -test shall be taken from the same part as the initial test bar, provided the re -tested section is immediately adjacent to the initial test location and it has approximately equal thickness. If this is not possible, retest bars shall be taken from the same location of another part belonging to the same master heat and heat treatment lot
Qualification of manufacturing procedure of A286 forging parts
The Manufacturing Process Plan (MPP) shall be submitted to the approval of clients Material
& Process Engineering dept. clients before qualification procedure begins. It shall detail at least
the following:
• type of ingot (supplier, manufacturing process, dimensions, and tests to beperformed);
• forging process;
• heat treatment process;
• tests on component.
In general, dissection of the first piece within the terms detailed in the part specification is required.
This activity may be omitted, upon decision of clients, if the supplier has already proven to be able to successfully produce components of similar shape, dimensions and manufacturing
process.
