This European Standard shall be given the status of a national standard, either by publication of an identical
16、text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by May 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible f
17、or identifying any or all such patent rights. Within its programme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 7 “Spheroidal graphite, silicon molybdenum and austempered ductile iron“ to prepare EN 16124. According to the CEN/CENELEC Internal Regulations, the national standards o
18、rganizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
19、 Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 16124:2012-02 EN 16124:2011 (E) 4 Introduction This European Standard classifies low-alloyed ferritic spheroidal graphite cast irons, principally used for their heat and oxidation resistance properties.
20、 NOTE Ferritic spheroidal graphite cast irons alloyed with silicon and molybdenum is also known as SiMo cast irons. Due to the ferritic structure and the silicon and molybdenum content, these cast irons allow producing castings which are resistant to distortion and oxidation at high temperatures. Ni
21、ne grades of low-alloyed ferritic spheroidal graphite cast iron are defined by their silicon and molybdenum content. Typical applications for the first three grades are medium to heavy castings like turbine housings and compressor parts. The other six grades are mainly applied for exhaust manifolds
22、and turbocharger parts in automotive applications. The mechanical properties of the material can be evaluated on machined test pieces prepared from cast samples or samples cut from a casting. Additional information on technical properties for low-alloyed ferritic spheroidal graphite cast iron is giv
23、en in Annex B and Annex C. DIN EN 16124:2012-02 EN 16124:2011 (E) 5 1 Scope This European Standard defines the grades and the corresponding requirements for low-alloyed ferritic spheroidal graphite cast irons for elevated temperature applications. These requirements are specified in terms of chemica
24、l composition: as given for each of the grades, graphite form and matrix structure: spheroidal graphite in a predominantly ferritic matrix, mechanical properties measured on machined test pieces prepared from cast samples. This European Standard does not cover technical delivery conditions for iron
