31、temperature range leading to a material condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are retained even after normalizing Note 1 to entry: The symbol for this delivery condition is N. Note 2 to entry: The definition is deviating fro
32、m EN 10052:1993. 4 Classification and designation 4.1 Classification The steels specified in this European Standard are non-alloy quality steels, except HCT600XB which is an alloy quality steel, in accordance with EN 10020. 4.2 Designation The steel grades are designated with steel names in accordan
33、ce with EN 10027-1. The corresponding steel numbers have been allocated in accordance with EN 10027-2. 5 Information to be supplied by the purchaser 5.1 Mandatory information The following information shall be supplied by the purchaser at the time of enquiry and order: a) quantity required; b) type
34、of flat products (sheet or strip); c) nominal dimensions of the product (length1), width, thickness); d) number of this European Standard; e) steel name or number (see Table 1 or 3); f) delivery condition (see 6.2 and 7.5); g) inspection document to be delivered (see 8.1.1). 1) For sheet only. BS EN
35、 10120:2017EN 10120:2017 (E) 6 5.2 Options A number of options are specified in this European Standard and listed below. If the purchaser does not indicate his wish to implement any of these options the products shall be supplied in accordance with the basic specification (see 5.1). 1) Information o
36、n the melting and de-oxidation process (see 6.1.1 and 6.1.2); 2) product analysis (see 7.1.2 and Table 4); 3) sampling conditions for the product analysis (see 9.2.2); 4) special marking conditions (see Clause 11). 5.3 Example of ordering 10 t sheets with nominal dimensions of thickness = 4,0 mm, wi
37、dth = 600 mm, length = 1 200 mm, made of the steel grade P265NB (1.0423) as specified in EN 10120, delivered normalized, descaled and oiled, inspection certificate 3.1 in accordance with EN 10204: 10 t sheet 600x1200x4,0 EN 10120 P265NB normalized and oiled EN 10204-3.1 or 10 t sheet 600x1200x4,0 EN
38、 10120 1.0423 normalized and oiled EN 10204-3.1 6 Manufacturing process 6.1 Steelmaking process 6.1.1 The melting and de-oxidation process shall be at the discretion of the manufacturer with the limitations to 6.1.2 and 6.1.3 and Table 1, unless otherwise agreed at the time of enquiry and order. 6.1
39、.2 The steel shall be manufactured using the electric arc process or an oxygen process. Other melting processes may be used by agreement at the time of enquiry and order. On request, the purchaser shall be informed of the process used. 6.1.3 The used type of de-oxidation shall ensure that the steel
40、has an acceptable degree of resistance to ageing (see Table 1, footnote b). 6.2 Delivery condition The delivery condition shall be specified at the time of enquiry and order. Usual delivery conditions are: a) hot rolled and normalized (N)2); b) hot rolled (AR); c) cold rolled. NOTE The delivery cond
41、ition “hot rolled and normalized2)” is generally used for gas cylinders which are only stress relieved after welding. The “hot rolled” delivery condition is only intended for gas cylinders which are normalized after welding. Gas cylinders which are made of steel grade HCT600XB, which is delivered “c
42、old rolled”, shall not be normalized after welding, because normalizing affects the mechanical properties of the material. 2) This includes the normalizing rolled condition.
