BS EN 10283 pdf free download.Corrosion resistant steel castings.
1 Scope
This document applies to corrosion resistant steel castings for general purposes.
This document relates to castings manufactured from martensitic, austenitic, fully austenitic and austenitic-ferritic steel grades characterized by their chemical composition (see Table 1) and mechanical properties (see Table 2).
in cases where castings are joined by welding by the founder, this document applies. in cases where castings are weided:
— to wrought products (plates, tubes, forgings);
— or by non-founders,
this document does not apply.

4 . Information to be supplied by the purchaser
5 Designations
In addition to EN 1559-2:2014: 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 1559-2:2014: 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 NOTE For austenitic, fully austenitic and ferritic-austenitic (duplex) grades with a carbon content greater than 0,030 %, when welding cannot be followed by heat treatment as solution annealing (+AT), there may be a risk of intergranular 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 processing7 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 (Rp02) for martensitic, austenitic, fully austenitic and austenitic-ferritic- austenitic steels; 1,0 % proof strength (Rp1,0) for austenitic and fully austenitic steels.BS EN 10283 pdf download.
