15、 EN 10349:2009 (E) 4 1 Scope This European Standard specifies austenitic manganese cast steels for wear-resistant service. The grades covered by this European Standard will experience maximum service life in applications where the surface of the casting is subject to impact. This European Standard r
16、etains the same format for clauses as EN 1559-1 and EN 1559-2. It shall be used in conjunction with these standards. Where no text is given under a clause heading, the corresponding clause of EN 1559-1 or EN 1559-2 applies. The structure of this standard is as follows: a) clauses and subclauses prec
17、eded by indicates no additional conditions to Part 1 or Part 21)of EN 1559; b) subclauses without any marking are mandatory. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For und
18、ated references, the latest edition of the referenced document (including any amendments) applies.

22、ss than 45 mm and the carbon content is less than 0,8 %. Where the thickness is 45 mm or greater and the carbon content is 0,8 % or greater Grade GX90MnMo14, and all other grades, shall be solution treated at temperatures not lower than 1 040 C and quenched in water. 7 Requirements 7.1 General 7.2 M

24、ween the purchaser and manufacturer. 7.2.2.2 Bend test Bend tests shall be carried out in accordance with EN ISO 7438. The type and location of bend test pieces shall be agreed between the manufacturer and purchaser. The test specimen shall withstand bending at room temperature (23 5) C through an a
25、ngle of 150 without breaking into two or more pieces. Surface cracks produced by bending are not considered as failure if the test piece remains in one piece. 7.2.2.3 Brinell Hardness test Hardness tests shall be carried out in accordance with EN ISO 6506-1. The hardness shall be a maximum of 300 HB
26、W, unless otherwise agreed between the manufacturer and purchaser. When machining of castings is required, it may be necessary to control hardness. In this case hardness testing shall be carried out after heat treatment and prior to machining. DIN EN 10349:2010-02 EN 10349:2009 (E) 6 7.2.3 Microstru

Samples may
29、be selected in the manufacturers works. Depending on the type of test, samples may be blocks or castings representative of the product. 8.2.6 Submission for specific inspection and testing to the inspection representative 8.2.6.1 General The manufacturer shall arrange with the purchaser, by mutual a
30、greement, the date of submission for inspection. The inspection representative shall have free access at any suitable time to the places in which the products to be inspected are manufactured and stored. He may indicate the samples to be selected in accordance with the specification. He shall have t
31、he option of attending the selection of samples, the preparation (machining and treatment) of the test pieces and carrying out the tests. However, an inspection representative who visits the workshops shall respect all of the safety regulations in force in the works and shall be accompanied, as far
32、as possible, by a representative of this works. 8.2.6.2 Conditions of acceptance If all the requirements of the order, and of this European Standard, are fulfilled, the lot is considered to conform and is accepted by the purchaser without prejudice to the inspection which may take place later at the
