This document specifies a method of converting room temperature percentage elongations after fracture obtained on various proportional and non-proportional gauge lengths to other gauge lengths. Formula (1), on which conversions are based, is considered to be reliable when applied to austenitic stainless steels within the tensile strength range 450 to 750 N/mm2 and in the solution treated condition. These conversions are not applicable to: a) cold reduced steels; b) quenched and tempered steels; c) non-austenitic steels. These conversions are not applicable when the gauge length exceeds 25√S0 or where the width to thickness ratio of the test piece exceeds 20.
Abstract
Overview - EN ISO 2566-2:2021 (Austenitic steels)
EN ISO 2566-2:2021 is the CEN-endorsed part of the ISO 2566 series that defines a method for converting room-temperature percentage elongation after fracture measured on one gauge length to equivalent elongation values on other gauge lengths for austenitic stainless steels. The conversions are based on an empirically derived statistical formula (Formula (1) in the standard, with an empirical exponent ≈ 0.127) and are supported by tables and figures (Tables 1–21, Figures 1–5) for common proportional and non‑proportional gauge lengths.
Key topics and technical requirements
- Scope and applicability
- Intended for austenitic stainless steels in the solution‑treated condition with tensile strength 450–750 N/mm².
- Not applicable to: cold‑reduced steels, quenched & tempered steels, and non‑austenitic steels.
- Not valid when gauge length > 25√S0 or when width/thickness ratio > 20.
- For strip thickness
