Stainless steels

Part 3: Technical delivery conditions for semi-finished products, bars, rods, wire, sections and

bright products of corrosion resisting steels for general purposes

English version of DIN EN 10088-3

Nichtrostende Stähle – Teil 3: Technische Lieferbedingungen für Halbzeug, Stäbe, Walzdraht, gezogenen Draht, Profile und Blankstahlerzeugnisse aus korrosionsbeständigen Stählen für allgemeine Verwendung

National foreword

This standard has been prepared by Subcommittee TC 23/SC 1 ‘Stainless steels’ (Secretariat: Germany) of ECISS.

The responsible German body involved in its preparation was the Normenausschuss Eisen und Stahl (Steel and Iron Standards Committee), Subcommittee 06/1 Nichtrostende Stähle . This standard covers technical delivery conditions for semi-finished products, bars, rods, wire, sections and bright products of corrosion resisting steels for general purposes.

Amendments

This standard differs from the August 1995 edition and DIN 17440, March 2001 edition, as follows.

a) The overall term for steels as in this standard has been amended to ‘corrosion resisting steels’, while the term ‘stainless steels’ now covers corrosion resisting, heat resisting and creep resisting steels.b) The clause on mechanical properties has been revised.c) The specifications for surface quality have been revised.

d) The specifications for physical and chemical analytical procedures have been revised.e) The following additional steel grades have been included:

four ferritic steel grades: X2CrTi17 (1.4520), X3CrNb17 (1.4511), X6CrMoNb17-1 (1.4526), X2CrTiNb18 (1.4509),

six martensitic steel grades: X15Cr13 (1.4024), X38CrMo14 (1.4419), X55CrMo14 (1.4110), X46CrS13 (1.4035), X40CrMoVN16-2 (1.4123), X2CrNiMoV13-5-2 (1.4415),

three precipitation hardening steel grades: X1CrNiMoAlTi12-9-2 (1.4530), X1CrNiMoAlTi12-10-2 (1.4596), X5NiCrTiMoVB25-15-2 (1.4606),

twelve austenitic steel grades: X5CrNi17-7 (1.4319), X9CrNi18-9 (1.4325), X5CrNiN19-9 (1.4315), X1CrNiMoN25-22-2 (1.4466), X1CrNiMoCuN24-22-8 (1.4652), X11CrNiMnN19-8-6 (1.4369), X12CrMnNiN17-7-5 (1.4372), X8CrMnNiN18-9-5 (1.4374), X8CrMnCuNB17-8-3 (1.4597),

X2CrNiMoCuS17-10-2 (1.4598), X1CrNiMoCuNW24-22-6 (1.4659), X2CrNiMnMoN25-18-6-5 (1.4565),two austenitic-ferritic steel grades: X2CrNiMoN29-7-2 (1.4477), X2CrNiMoSi18-5-3 (1.4424).

f) Specifications have been included for the mechanical properties of bright steel products of ferritic, martensitic, precipitation hardening, austenitic and austenitic-ferritic bars, and for the tensile strength of wires.

g) An annex has been included on the availability of corrosion resisting steel wire in the cold work-hard-ened condition.
