EN 10088-3 Specification

Scope

1.1 This part of EN 10088 specifies the technical delivery conditions for semi-finished products, hot or cold formed bars, rods, wire, sections and bright products of standard grades and special grades of corrosion
resisting stainless steels for general purposes.

1.2 The general technical delivery conditions specified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.

1.3 This European Standard does not apply to components manufactured by further processing of the product forms listed in 1.1 with quality characteristics altered as a result of such further processing.

a  Elements not quoted in this table may not be intentionally added
to the
steel without the agreement of the purchaser except for finishing the cast. All appropriate
precautions
are to be taken to avoid the addition of such elements from scrap and other materials used in
production which would impair mechanical properties and the suitability of the steel.
b  Particular ranges of sulphur content may provide improvement of
particular properties. For machinability a controlled sulphur content of 0,015 % to 0,030 % is
recommended
and permitted. For weldability, a controlled sulphur content of 0,008 % to 0,030 % is recommended
and permitted. For polishability, a controlled sulphur content of 0,015 % max. is
recommended.

appropriate precautions are to be taken to avoid the
addition of such elements from scrap and other materials used in production which would impair
mechanical properties and the suitability of the steel.
b  Particular ranges of sulphur content may provide improvement of
particular properties. For machinability a controlled sulphur content of 0,015 % to 0,030 % is
recommended and permitted. For weldability,
a controlled sulphur content of 0,008 % to 0,030 % is recommended and permitted. For

c  Where for special reasons, e.g. hot workability for the
fabrication of seamless tubes where it is necessary to minimize the delta ferrite content, or with
the aim of low magnetic permeability, the maximum
Ni content may be increased by the following amounts:

a  Elements not listed in this table shall not be intentionally
added to the steel without the agreement of the purchaser except for finishing the cast. All
appropriate precautions are to be taken to
avoid the addition of such elements from scrap and other materials used in production which would
impair mechanical properties and the suitability of the steel.
b  Particular ranges of sulphur content may provide improvement of
particular properties. For machinability a controlled sulphur content of 0,015 % to 0,030 % is
recommended and permitted. For
weldability, a controlled sulphur content of 0,008 % to 0,030 % is recommended and permitted. For
polishability, a controlled sulphur content of 0,015 % max. is recommended.
c  By agreement, this grade can be delivered with a Pitting
Resistance Equivalent Number (PRE = Cr +3,3Mo + 16N, compare Table C.1 of EN 10088-1) greater than
34.
