28、Copy, (c) BSI EN 13835:2002 (E) 4 Introduction This European Standard deals with the classification of a range of cast irons principally used for their heat and cor- rosion resistance properties. These properties are obtainable from the Engineering grades in this standard. The Special Purpose grades
29、 also exhibit heat and corrosion resistance properties, but are used principally for their magnetic properties, or very low expansion characteristics. The austenitic cast irons are a range of high-alloyed materials with an austenitic matrix, containing nickel, man- ganese and sometimes copper and ch
30、romium. Carbon is present either as graphite flakes or as spheroids. The spheroidal graphite grades have superior mechanical properties. The properties of the austenitic cast irons depend upon them having the appropriate structure and mechanical pro- perties for the application. These properties are
31、 dependent upon the control of metal composition within the specified grades and the metal processing route. Typical applications for the various grades are given in annex A. 1 Scope This European Standard specifies the grades and corresponding requirements for austenitic cast irons. These requireme
32、nts are specified in terms of: graphite form and metal structure: either flake or spheroidal graphite in an austenitic matrix; chemical composition: as given for each of the grades; mechanical properties: obtained from separately cast samples. 2 Normative references EN 1559-1, Founding Technical con

34、 3 Terms and definitions For the purposes of this European Standard, the following term and definition apply. 3.1 austenitic cast iron cast material with an austenitic matrix which is iron and carbon based and alloyed with nickel and manganese, copper and/or chromium in order to stabilize the austen
35、itic structure at room temperature. The graphite can be present in flake or spheroidal form Austenitic spheroidal graphite cast iron can be used for pressure equipment, e.g. for compressor housings. The suitable material grades for pressure applications and the conditions for their use are given in
36、specific product or application standards. For the design of pressure equipment, specific design rules apply. ! “ The following referenced documents are indispensable for the application of this document.

38、designated either by symbol or by number as given in Tables 1 to 4. 5 Order information The following information shall be supplied by the purchaser: a) the number of this European Standard (EN 13835); b) the designation of the material; c) any special requirements which have to be agreed by the tim
39、e of acceptance of the order in accordance with EN 1559-1 and EN 1559-3. 6 Manufacture Unless otherwise specified by the purchaser, the method of manufacture of austenitic cast irons shall be left to the discretion of the manufacturer. The manufacturer shall ensure that the requirements defined in t
40、his standard are met for the material grade specified in the order. Any agreement between the manufacturer and the purchaser shall be made by the time of acceptance of the order. NOTEFor certain applications heat treatment of austenitic cast irons is beneficial, but should only be specified where se
41、rvice conditions demand such treatment. The heat treatment processes employed are stress relieving and high temperature stabilising treatments. Details of these treatments are given in annex B. 7 Requirements 7.1 Chemical composition The chemical composition of austenitic cast iron grades shall be i
42、n accordance with Table 1 for the Engineering grades and Table 2 for the Special Purpose grades. Spheroidal graphite grades are produced either by magnesium treatment or by treatment with another suitable nodulariser. Unless otherwise specified, other elements may be present at the discretion of the
43、 manufacturer provided that they do not alter the structure or adversely affect the properties. If the presence of any element specified in Tables 1 or 2 is required to be outside the limits indicated, or if any other elements are required, their contents shall be agreed between the manufacturer and
44、 the purchaser and specified in the order. 7.2 Mechanical properties The mechanical properties of the grades of austenitic cast irons obtained from separately cast samples shall be in accordance with Table 3 for the Engineering grades and Table 4 for the Special Purpose grades. Other requirements, s
45、uch as the mechanical properties to be met on cast-on samples or at specified locations on the castings, shall be agreed between the manufacturer and the purchaser and specified in the order. In such cases the position of the cast-on sample or the specified location on the casting shall be agreed be
46、tween the manufacturer and the purchaser and specified in the order.

47、 which they represent. 8.2 Frequency and number of tests Samples, representative of the material, shall be produced at a frequency in accordance with the in-process quality assurance procedure adopted by the manufacturer. In the absence of either an in-process quality assurance procedure or any agre
48、ement between the manufacturer and the purchaser, a minimum of one sample shall be produced to confirm the material at a frequency to be agreed between the manufacturer and the purchaser by the time of acceptance of the order. When impact tests are agreed by the time of acceptance of the order, samp
49、les shall be produced at a frequency to be agreed between the manufacturer and the purchaser. 8.3 Samples Unless otherwise agreed by the time of acceptance of the order, samples for mechanical testing shall be cast separately in sand moulds from the same ladle as that used to pour the casting(s). Separately cast samples shall meet the requirements of either Figures 1, 2 or 3. Separately cast samples shall not be removed from t
