6 Requirements
6.1 Steelmaking process
Unless otherwise agreed at the time of enquiry and order, the steelmaking and manufacturing process for steels
conforming to this document shall be at the discretion of the manufacturer.
6.2 Delivery condition
The products shall be supplied in the delivery condition agreed at the time of enquiry and order by reference to the
conditions given in Table 7 and, where different alternatives exist, to the treatment conditions given in Tables 8 to
19 and 25 (see also Annex A).
6.3 Chemical composition
6.3.1 The chemical composition requirements given in Tables 2 to 5 apply in respect of the chemical
composition according to the cast analysis.
6.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Tables 2 to 5
by the values listed in Table 6.
6.4 Chemical corrosion properties
Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and
austenitic-ferritic stainless steels the specifications in Tables 8, 11 and 12 apply.
NOTE 1 EN ISO 3651-2 is not applicable for testing martensitic and precipitation hardening steels.
NOTE 2 The corrosion resistance of stainless steels is very dependent on the type of environment and can
therefore not always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the available
experience of the use of the steels.
6.5 Mechanical properties
6.5.1 The mechanical properties at room temperature as specified in Tables 8 to 12 apply for hot worked
products of every condition, condition 1U and semi-finished products excluded, for cold processed products in
condition 2D (excluding wire), and for each specified heat treatment condition.
For cold processed products of every specified condition, condition 2D and wire excluded, and each specified
heat treatment condition, the mechanical properties at room temperature as specified in Tables 13 to 17 apply.
For these products, the condition is the prime property with the mechanical properties secondary.
If by agreement at the time of ordering the products are to be supplied in a non-heat-treated condition, the
mechanical properties specified in Tables 8 to 17 shall be obtained from reference test pieces which have
received the appropriate heat treatment (simulated heat treatment).
For wire, the properties as specified in Tables 18 and 19 apply.
For bars which are intentionally cold work hardened in order to increase their tensile strength to a specified level,
the mechanical properties at room temperature as specified in Table 25 apply. For these products, the mechanical
properties are prime, with the condition a secondary property.
NOTE Austenitic steels are insensitive to brittle fracture in the solution annealed condition. Because they do not
have a pronounced transition temperature, which is characteristic of other steels, they are also useful for application
at cryogenic temperatures.

parallel length). In cases of doubt and in referee testing these test pieces shall be used.
For wire of nominal diameter < 4 mm, the tensile test is made directly on the product using a gauge length of
100 mm.
The tensile strength, elongation after fracture and the 0,2 %-proof strength shall be determined. In addition, for
austenitic steels only, the 1 %- proof strength shall be determined.
7.4.3 If a tensile test at elevated temperature has been ordered, this shall be carried out in accordance with
EN 10002-5. If the proof strength is to be verified, the 0,2 %- proof strength shall be determined, for ferritic,
martensitic, precipitation hardening and austenitic-ferritic steels. In the case of austenitic steels the 0,2 %- and
the 1 %- proof strength shall be determined.
7.4.4 If an impact test has been ordered, it shall be carried out in accordance with EN 10045-1 on test
pieces with a V-notch. The average obtained from three test pieces is considered to be the test result (see
also EN 10021).
7.4.5 The Brinell hardness test shall be carried out in accordance with EN ISO 6506-1.
7.4.6 The resistance to intergranular corrosion shall be tested in accordance with EN ISO 3651-2.
