It may be agreed at the time of ordering, until this EURONORM has been adopted as a European Standard, that either this Euronorm or a corresponding national stan- dard should be applied. Page 6 EN 10095 : 1999 3 Definitions For the purpose of this European Standard, the

28、 following definition applies in addition to the definitions given in EN 10021, EN 10052, EN 10079, EN IS0 377 and IS0 14284: 3.1 Heat-resistance: Property of materials that are used at above 550C (for steels: wustite point) due to their excellent resistance to the effects of hot gases and products

29、of combustion as well as their resistance to the influence of molten salts and molten metals but also showing good mechanical properties during short and long-term stressing. 4 Classification and designation 4.1 Classification Materials covered in this European Standard are classified according to t

30、heir structure into - ferritic steels; - austenitic-ferritic steels; - austenitic steels; and - austenitic nickel alloys. 4.2 Designation The names and numbers of the steels (see table 1 and 2) were formed in accordance with EN 10027-1 and EN 10027-2 respectively. NOTE: Explanation on the designatio

31、n of nickel alloys (see table 3) - name: The preceding chemical symbols indicate the main alloy elements and the figure immediately following indicates the average content of these alloys subsequently followed by the symbol for the other added important alloy elements. - material number: The structu

32、re is set out according to EN 10027-2 with the number 2 for the material group number. This material group comprises chemically resistant and high temperature or heat resistant nickel and cobalt alloys. 5 Information to be supplied by the purchaser 5.1 Mandatory information The following information

33、 shall be supplied by the purchaser at the time of enquiry and order: a) the quantity to be delivered; Page 7 EN 10095 : 1999 b) the designation of the product form (e.9. bar or rod, strip or sheet); c) where an appropriate dimensional standard is available (see annex A) the number of the standard a

34、nd the indications required by this, also the nominal dimensions and tolerances; d) the type of material (steel or nickel alloy); e) the number of this European Standard (EN 10095); f) the name or number of the steel grade or nickel alloy (see 4.2); g) if for the relevant grade in the table more tha

35、n one treatment condition for the mechanical properties is covered, the symbol for the desired heat treatment condition or cold worked condition: h) the desired process route (see symbols in tables 7 and 8). EXAMPLE: 1 O t rounds of a steel grade with the name XlONiCrAITi32-21 and the number 1.4876

36、as specified in EN 10095 of 50 mm diameter, dimensional tolerances as specified in EURONORM 60, in process route 1D. 10 t rounds EURONORM 60 - 50 steel EN 10095 - X1 ONiCrAlTi32-21+1 D or 10 t rounds EURONORM 60 - 50 steel EN 10095 - 1.4876+1 D 5.2 * Options A number of options are specified in this

37、 European Standard and listed below. If the purchaser does not indicate his wish to implement one of these options, the supplier shall supply in accordance with the basis specification of this European Standard (see 5.1). a) any requirement concerning a special melting or forming process (see 6.1);

38、b) any requirement relating to surface quality (see 7.4); c) any requirement concerning the issue of an inspection document (see 8.2); d) any requirement concerning the method of analysis to determine the product analysis (see 8.4.1); e) any requirement concerning special marking of the products (se

39、e 9.2, 9.3 and table 10): Page 8 EN 10095 : 1999 6 Manufacturing process 6.1 * General Unless a special melting or forming process is agreed when ordering, the production process for steels and alloys conforming to this European Standard shall be at the discretion of the manufacturer. 6.2 Delivery c

40、ondition The products shall be supplied in the delivery condition agreed in the order by reference to the process route given in tables 7 and 8 and to the treatment conditions given in table B.1. 7 Requirements 7.1 General The supplier shall operate and certify a quality system in accordance with EN

41、 IS0 9002*). 7.2 Chemical composition 7.2.1 The chemical cornposition requirements given in tables 1 to 3 apply with respect to the cast analysis. 7.2.2 The product analysis may deviate from the limiting values for the cast analysis given in tables 1 to 3 by the values listed in tables 4 and 5. 7.3

42、Mechanical properties The mechanical properties at room temperature as specified in table 6 apply for each specified heat treatment condition. This does not apply to the process route 1 U (hot rolled, not heat treated, not descaled) and to semi-finished products. If by agreement at the time of order

43、ing, the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in table 6 shall be obtainable from reference test pieces which have received the appropriate heat treatment (simulated heat treatment). 7.4 Surface quality Slight surface imperfections, inheren

44、t in the production process, are permitted. This requirement is also fulfilled by a quality system in accordance with EN IS0 9001. Page 9 EN 10095 : 1999 00 If more exact requirements for the surface quality are necessary, these shall be agreed at the time of enquiry and order. When products are del

45、ivered in coil form, the degree and extent of such imperfections may be expected to be greater due to the impracticality of removing short lengths of coil. For hot-rolled quarto-plates, the specification in EN 101 63-2 class A3, applies unless otherwise stated. For long products, where appropriate t

46、he requirements shall be on the basis of EN 10221 7.5 Dimensions and tolerances on dimensions The dimensions and the tolerances on dimensions are to be agreed at the time of enquiry and order, as far as possible with reference to the dimensional standards listed in Annex A. 7.6 Calculation of mass a

47、nd tolerances on mass 7.6.1 When calculating the nominal mass from the nominal dimensions the values given in table B.5 shall be used as a basis for the density of the steel concerned. 7.6.2 If the tolerances on mass are not specified in the dimensional standard listed in Annex A, they shall be agre

48、ed at the time of enquiry and order. 8 Inspection and testing 8.1 General The manufacturer shall carry out appropriate process control, inspection and testing to assure himself that the delivery complies with the requirements of the order. This includes the following: - a suitable frequency of verif

49、ication of the dimensions of the products, - an adequate intensity of visual examination of the surface quality of the products, - an appropriate frequency and type of test to ensure that the correct grade is used. The nature and frequency of these verifications, examinations and tests is determined by the manufacturer, in the light of the degree of consistency that has been determined by the evidence of the quality system. In view of this, verifications by specific tests for these requirements are not necessary unless otherwise agreed. Page 1 O EN 10095 : 1999 8.2 0. Types a
