Material requirements. Defined by product form.
Creep-resisting steel and nickel-alloy flat products for service under sustained high-temperature stress. The standard excludes aerospace and pressure-purpose specifications.
Data edition: EN 10302:2008, Tables 1, 2, 7 and 8. Selected flat-product rows at 3–20 mm are shown. For nickel-alloy flat products below 3 mm, the Table 8 elongation minima are five percentage points lower. The 800H and 800HT entries identify EN 1.4958 and 1.4959; trade-name chemistry and heat-treatment restrictions can be narrower than the EN grade.

Room-temperature properties. Rp0.2 and Rp1.0 are minimum proof strengths; Rm is tensile strength. A80 applies below 3 mm thickness; A applies from 3 mm using a proportional gauge length of 5.65√S₀. +AT = solution annealed; +A = annealed; +RA = recrystallization annealed; +P = precipitation hardened. Strength is in MPa (N/mm²).
