SPECIFICATION OVERVIEW
Material requirements. Defined by product form.
Stainless steel flat products for pressure purposes.
Data edition: EN 10028-7:2007, Tables 3, 4, 9 and 10. Austenitic values shown are transverse; narrow strip tested longitudinally uses Rp0.2 minus 15 MPa, A80 minus 5 points and A minus 2 points. Stretcher-levelled 1.4301 has elongation minima 5 points lower. Duplex longitudinal values are shown separately for strip widths below 300 mm.

Composition is cast analysis in mass %. Values marked ≤ are maxima; paired values are ranges. Ti and Nb expressions use the carbon content by mass. The symbol — means that this table has no limit for that entry.

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).
