DIN EN 1564:2012-01 EN 1564:2011 (E) 5 Introduction Ausferritic spheroidal graphite cast iron is a cast alloy, iron, carbon and silicon based, the carbon being present mainly in the form of spheroidal graphite particles. NOTE 1 Ausferritic spheroidal graphite

30、cast iron is also known as austempered ductile iron (ADI). Compared with the spheroidal graphite cast irons as specified in EN 1563 1, this material combines higher strength and toughness properties as a result of the ausferritic matrix structure. This European Standard classifies ausferritic sphero

31、idal graphite cast irons in accordance with the mechanical properties of the material. The mechanical properties of these ausferritic spheroidal graphite cast irons depend on the graphite and the matrix structure. The required structure is obtained by selecting the appropriate composition and subseq

32、uent processing. The mechanical properties of the material can be evaluated on machined test pieces prepared from cast samples or samples cut from a casting. Five grades of ausferritic spheroidal graphite cast iron are defined by the mechanical properties measured on machined test pieces prepared fr

33、om cast samples. When, for these grades, hardness is a requirement of the purchaser as being important for the application, Annex C provides guidance values for hardness. Two grades of ausferritic spheroidal graphite cast iron are defined in Annex A in accordance with their hardness. These cast iron

34、s are used in applications (e.g. mining, earth moving) where high abrasion resistance is required. In this standard a new designation system by number, as established in EN 1560 2, is given. NOTE 2 This designation system by number is based on the principles and the structure as set out in EN 10027-

35、2 3 and so corresponds with the European numbering system for steel and other materials. Some ausferritic spheroidal graphite cast iron grades can be used for pressure equipment. The permitted material grades of ausferritic spheroidal graphite cast iron for pressure applications and the conditions f

36、or their use are given in specific product or application standards. For the design of pressure equipment, specific design rules apply. Annex ZA gives information relating to the conformance of permitted ausferritic spheroidal graphite cast iron grades to the Pressure Equipment Directive 97/23/EC. D

37、IN EN 1564:2012-01 EN 1564:2011 (E) 6 1 Scope This European Standard defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons. This European Standard specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical

38、 properties measured on machined test pieces prepared from cast samples. This European Standard also specifies two grades by a classification as a function of hardness. This European Standard does not cover technical delivery conditions for iron castings, see EN 1559-1 4 and EN 1559-3 5. NOTE Grades

39、 given in Annex A are not intended for pressure equipment applications. 2 Normative references The following referenced documents are indispensable for the application of this document.

43、ic matrix structure NOTE Usually this ausferritic matrix structure is obtained by an austempering heat treatment. 3.2 graphite spheroidising treatment operation that brings the liquid iron into contact with a substance to produce graphite in the predominantly spheroidal (nodular) form during solidif

44、ication NOTE This operation is often followed by a second one called inoculation. DIN EN 1564:2012-01 EN 1564:2011 (E) 7 3.3 austemper heat treatment of spheroidal graphite cast iron process, consisting of heating the castings above the AC1temperature and holding a sufficient time to increase the ca

45、rbon content of the austenite, followed by cooling at a rate sufficient to avoid the formation of pearlite and transforming the matrix structure for a time and a temperature (above the martensite start temperature) sufficient to produce the desired properties NOTE This process produces a microstruct

46、ure that consists predominantly of ferrite and austenite. This microstructure is called ausferrite. 3.4 cast sample quantity of material cast to represent the cast material, including separately cast sample, side by side cast sample and cast-on sample 3.5 separately cast sample sample cast in a sepa

47、rate sand mould under representative manufacturing conditions and material grade 3.6 side-by-side cast sample sample cast in the mould alongside the casting, with a joint running system 3.7 cast-on sample sample attached directly to the casting 3.8 relevant wall thickness wall thickness representati

In the case of samples cut from the casting the letter C is added at the end of the designation by symbol, see EN
