Discussion Overview

The discussion revolves around the atomic makeup of Hastelloy N, focusing on its composition and the specific elements involved. Participants explore the percentages of various components in the alloy, including comparisons with other sources.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses difficulty finding the atomic makeup of Hastelloy N and seeks clarification on its components.
  • Another participant mentions that Wikipedia provides mass percentages that can be converted to atomic makeup.
  • A participant calculates the composition of Hastelloy N, listing elements such as Cobalt, Chromium, Molybdenum, Tungsten, Iron, Silicone, Manganese, and Carbon, suggesting that Nickel makes up the remainder of the alloy.
  • One participant confirms that Nickel constitutes the remaining percentage of the alloy.
  • A detailed representation of the alloy's composition is provided, including maximum values for each element.
  • A participant references an external document that specifies the maximum percentage of Nickel in Hastelloy N as 71%.
  • Another participant expresses appreciation for the provided link to the external document.

Areas of Agreement / Disagreement

Participants generally agree on the presence of Nickel as the remaining component of Hastelloy N, but there are variations in the specific percentages and elements listed, indicating some uncertainty and lack of consensus on the exact composition.

Contextual Notes

There are limitations regarding the precision of the percentages and the definitions of the components, as well as potential discrepancies between different sources of information.

I understand there are a few different types, but with no luck on Wikipedia or Google I still need the atomic makeup of these alloys.
 
Chemistry news on Phys.org
Wiki gives mass percentages of components, these are easy to convert.

I can't believe I missed that.

Okay adding the values for Hastelloy N I get Cobalt, Chromium, Molybdenum, Tungsten, Iron, Silicone, Manganese, and Carbon at a maximum of 32.38% by weight, does this mean at minimum the remainder is Nickel at 67.62% by weight?
 
Yes, nickel is everything else.
 
Okay, well here it is, the * represents maximum values for that element:
Co*1.2Cr49.5Mo61.3W*1Fe*32.9Si*13.1Mn*5.37C*2.45Ni434.9

And for Hastelloy N alloyed with Cu, Ti, and Al:
Co*1.2Cr49.5Mo61.3W*1Fe*32.9Si*13.1Mn*5.37C*2.45Ni429.5(Al+Ti)*4.9Cu*2.02
 
www.haynesintl.com/pdf/h2052.pdf
There the amount of Ni in % is explicitly specified as maximally 71%.
