INCOLOY alloy 800H

(UNS N08810)

It had been known for some time that higher carbon

alloy 800 had higher creep and rupture properties than

low-carbon material. For that reason, Special Metals

had melted to a carbon range of 0.05 to 0.10% except

for special orders where customers specified a lower

carbon content. The carbon range of 0.05 to 0.10% is

within the ASTM and ASME specification limits for

alloy 800 and is in the upper portion of that range.

Special Metals generated data for this material and

presented them to the ASME Code. The Code approved

higher design stresses for Section I and Divisions 1 and

2 of Section VIII, which appeared in Code Case 1325-

7. Note that alloy 800H required not only a carbon

range of 0.05 to 0.10% but also an average grain size of

ASTM 5, or coarser.

With the issuance of Code Case 1325-7 and the

common use of the term “800H”, there was no longer a

need to refer to “Grade 2” because it was replaced by

800H, and the material that had been called Grade 1

became, simply, INCOLOY alloy 800.

Available Product Forms:
