EN 10088-3:2014 (E) 8 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 austenitic, austenitic-ferritic and ferritic stainless steels the specifications in Tables 8, 9 and 10 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. 6.5.2 The values in Tables 20 to 24 apply for the 0,2 %- and 1 %- proof strength at elevated temperatures.

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 austenitic, austenitic-ferritic
and ferritic stainless steels the specifications in Tables 8, 9 and 10 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.
6.5.2 The values in Tables 20 to 24 apply for the 0,2 %- and 1 %- proof strength at elevated temperatures.

At the time of enquiry and order it may be agreed that the product shall be delivered with a surface being technically defect free by
manufacture. In this case, also the maximum % of delivered weight in excess of permissible depth of discontinuities shall be agreed.
For further information, e.g. roughness in conditions 2G and 2P, see Table 7.
6.7 Internal soundness
The products shall be free of internal defects which would exclude them from being used for their usual
purpose. At the time of enquiry and order ultrasonic testing of H-beams with parallel flanges and IPE-beams
may be agreed in accordance with EN 10306 and ultrasonic testing of steel bars may be agreed in
accordance with EN 10308.
6.8 Formability at room temperature
Cold formability may be verified by elongation in the tensile test.
6.9 Dimensions and tolerances on dimensions and shape
The dimensions and the tolerances on dimensions are to be agreed at the time of enquiry and order, as far as
possible with reference to the dimensional standards listed in Table 7 and in Annex C.
