7 Requirements
7.1 General
7.2 Material
7.2.1 Chemical composition
In addition to EN 1559-2:2014:
the chemical composition determined by a cast analysis shall conform to the values given in Table 1 of this document;
elements unspecified in Table 1 of this document shall not be intentionally added without agreement of the purchaser other than for the purpose of finishing the heat. If not otherwise agreed the maximum values in % (by mass) given in Table 3 shall be applicable;
permissible deviations between the specified cast analysis and the product analysis are indicated in EN 1559-2:2014, Table 1.
7.2.2 Mechanical properties
7.2.2.1 The mechanical 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 (Ro.z) for martensitic, austenitic, fully austenitic and austenitic-fernticaustenitic steels;
— 1,0 % proof strength (R1.o) for austenitic and fully austenitic steels.
7.2.3 Other properties
7.3 Casting
7.3.1 Chemical composition
7.3.2 Mechanical properties
7.3.3 Outer and inner conditions (non-destructive testing)
7.3.4 Condition of the casting
7.3.5 Mass of the casting
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 365 1-2.
NOTE All grades of this European document have performed satislactorily 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 with an inspection document 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-destructive 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.
8.3.2 For castings exceeding 1 000 kg in mass, each individual casting shall be regarded as the test
unit.
