5 Designations
In addition to EN 1559-2:20 14: For a steel grade manufactured to different strength levels, according to the heat treatment, a suffix shall be added in accordance with EN 10027-1.
6 Manufacture
6.1 Manufacturing process
6.1.1 MeltIng
In addition to EN 1559-2:20 14: Alternative processes are left to the discretion of the manufacturer.
6.1.2 Heat treatment
Unless otherwise agreed, the type of heat treatment represented by its symbol shall comply with
Table 2. For some grades there are different options with different mechanical properties given in
Table 2.
6.2 Welding operations
6.2.1 . General
NOTF For austenitic. fully austerntic and ferritic-austenitic (duplex) grades with a carbon content greater than 0,030 %. when welding cannot be followed by heat treatment as solution annealing (iAT). there may be a risk of lntergranular corrosion.
6.2.2 Production welding
In addition to EN 1559-2:2014:
— information on preheat and interpass temperatures as well as on post weld heat-treatment and the corresponding welding groups as defined in EN ISO 11970 Is given In Annex A.
6.3 . Further processing
7.2.2 Mechanical properties
7.2.2.1 The mecharncal properties shall conform to the values given in Table 2. They are verified on samples (see 8.4). In all cases the maximum thickness shall be limited to 150 mm.
•. In cases where the ruling thickness specified by the purchaser is above the maximum thickness given in Table 2, the mechanical properties shall be agreed.
7.2.2.2 The values of yield and tensile strength also apply to the casting itself up to the maximum wall thickness as given in Table 2.
The yield strength values at room temperature correspond to:
— 0,2 % proof strength (R) for martensitic, austenitic, fully austenitic and austenitic-ferriticaustenitic steels;
— 1,0% proof strength (R1,o) for austenitic and fully austenitic steels.
7.3.6 . Additional requirements regarding the condition of the casting
7.4 Corrosion behaviour
Austenitic steel grades shall be resistant to intergranular corrosion when tested according to
EN ISO 3651-2.
NOTE All grades of this European document have performed satisfactorily for a long time. However, it Is difficult to provide accurate information on their corrosion resistance. Values obtained under laboratory test conditions are not always adequate for the real application. Additives and contamination in the corrosive media can give rise to different results.
Grades may be selected by the pitting index’ P.1. = % Cr + 3,3 x % Mo + 16 x % N. Based upon this a minimum pitting index can be required by agreement.
8 Inspection
8.1 General
In addition to EN 1559-1:2011:
a) Castings manufactured according to this standard can be supplied witn an inspection aocurnenr according to EN 10204;
b) If, in the case of specific inspection, the issue of an Inspection certificate has been agreed this shall include the following:
1) the amounts of all elements specified (for the cast analysis) for the steel grade required;
2) the results of the mechanical test as required for the specific steel grade;
3) a statement on the result of agreed dimensional check and non-destnictive testing;
4) •. the result of any further mutually agreed testing.
8.2 .Type of inspection document and type of inspection
8.3 .Test unit
8.3.1 For castings under 1 000 kg in mass the delivered quantity shall be subdivided into lots covering castings of the same type from the same melt and having undergone the same heat treatment. The mass of a lot (test unit) shall not be greater than 5 000 kg.BS/EN 10283-2019 pdf download.
