EN 10293-2015 pdf download.Steel castings – Steel castings for general engineering uses.
This EN 10293 applies to steel castings:
— for general engineering uses. Its uses include machinery (mechanical, electrical…), automotive industries, railroad, armament, agricultural equipment, mining, etc.
In cases where castings are joined by welding by the founder, this document applies. In cases where castings are welded:
— to wrought products (plates, tubes, fc>rgings…), or by non-founders,
this document does not apply.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

In cases of grades with different mechanical properties relating to heat treatment conditions the purchaser shall specify the heat treatment symbol (see Clause 5).
5 Designation
In addition to EN 1559-2:2014:
— for a steel grade which can be delivered to different strength levels, according to the heat treatment, a suffix shall be added in accordance with Table 3. For example: G26CrMo4 +QT1.

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:
— 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 2 shall be applicable;
— permissible deviations between the specified cast analysis and the product analysis are indicated in Table 1 of
EN 1559-2:2014.
7.2.2 Mechanical properties In addition to EN 1559-2:2014:
7.2.2.1 The mechanical properties shall conform to the values given in Table 3,
These values apply up to the maximum wall thickness given in Table 3. They are verified on test blocks of relevant thickness (see 8.4.1 of EN 1559-2:2014). In all cases, the maximum wall thickness of test blocks shall be limited to 150 mm.
• In cases where the ruling thickness defined by the purchaser is above the maximum thickness given In Table 3, the foreseeable lowering of the mechanical properties shall be agreed.
7.2.2.2 The yield strength values at room temperature correspond to 0,2 % proof strength (RpO,2).
7.2.2.3 In cases wtere two impact values are given, at test temperature specified in Table 3 the purchaser shall state which impact value is required. If there is no such statement in the enquiry and order the impact test shall be conducted at room temperature.
