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 B).
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 shall 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.

---------------------- Page: 10 ----------------------
oSIST prEN 10088-3:2022
prEN 10088-3:2021 (E)
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.
A number of grades in Tables 2 to 5 are not listed or have limited information included in Tables 13 to
25. In this case, grade dimensions and corresponding mechanical properties shall be agreed upon at the
time of enquiry and order.
6.5.2 The values in Tables 20 to 24 apply for the 0,2 %- and 1 %- proof strength at elevated
temperatures.
6.6 Surface quality
The available surface finishes are given in Table 7. Slight surface imperfections, inherent to the
production process, are permitted. Exact requirements concerning maximum depth of acceptable
discontinuities for bars, rods and sections in the relevant conditions are given in Table 1.

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.
For wires supplied in 2H condition according to Table 18 or 2B according to Table 19 the surface
quality shall be agreed upon at the time of enquiry and order.
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.
