This Standard Specification covers the grades of
wrought steels and nickel alloys listed in Tables below
which are usually employed for products, for which
the main requirement is their resistance to the effects
of hot gases and products of combustion at
temperatures above 550 8C.
EN 10095 specifies the technical delivery
conditions for semi-finished products, for hot or cold
rolled sheet/plate and strip, hot or cold formed bars,
rods and sections of heat resisting steels and nickel
alloys.
Materials covered in this European Standard are
classified according to their structure into:
- ferritic steels.
- austenitic-ferritic steels.
- austenitic steels.
- austenitic nickel alloys.

1)Elements not listed in the table may not be intentionally added to the alloy without the agreement of the purchaser except for finishing the cast. All appropriate precautions are to be taken to avoid addition of such elements from scrap and other materials used in production which would impair mechanical properties and the suitability of the alloy. 2) A maximum of 1,5 % Co is allowed and counted as nickel. Reporting of cobalt is not required. *) Patented steel grade. |

1) The maximum HB values may be raised by 100 units or the maximum tensile strength value may be raised by 200 N/mm2 and the minimum elongation value be lowered to 20 % for sections and bars of ≤ 35 mm thickness having a final cold deformation. 2) For guidance only. 3) For rods, only the tensile strength values apply. |
