Page4 EN 10025-2: 2004 1 Scope Part 2 of this document, in addition to Part 1, specifies the technical delivery conditions for flat and long products and semi-finished prroducts which are mea
26、nt for further processing to flat and long products of hot rolled non-alloy quality steels in the grades and qualities given in Tables 2 to 6 (chemical composition) and Tables 7 to 9 (mechanical properties) in the delivery conditions as given in 6.3. Three engineering steels are also specified in th
27、is document (see Tables 3 and 5) (chemical composition) and Table 8 (mechanical properties). This document does not apply to structural hollow sections and tubes (see EN 10210-1 and EN 10219-1 ). The technical delivery conditions apply to thicknesses ;: 3 mm and $ 150 mm for long products of steel g
28、rade S450JO. The technical delivery conditions apply to thicknesses $ 250 mm for flat and long products of all other grades and qualities. In addition for flat products of qualities J2 and K2 the technical conditions apply to thicknesses $ 400 mm. Products made of steel grades S185, E295, E335 and E
29、360 cannot be CE marked. The steels specified in this Part 2 are not intended to be heat treated except products delivered in delivery condition +N. Stress relief annealing is permitted (see also the NOTE in 7.3.1.1 of EN 10025-1:2004). Products delivered in +N condition can be hot formed and/or nor
30、malized after delivery (see Clause 3). NOTE 1 Semi-finished products which are to be converted to rolled finished products conforming to this document should be the subject of special agreement at the time of the enquiry and order. The chemical composition can also be agreed at the time of the order
31、, however the values should be within the limits of Tables 2 and 3. NOTE 2 For certain grades and product forms suitability for particular applications may be specified at the time of the enquiry and order (see 7.4.2, 7.4.3 and Table 10). 2 Normative references The following referenced documents are

44、1 normalizing rolling rolling process in which the final deformation is carried out in a certain 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 The abbreviat
45、ed form of this delivery condition is +N NOTE In international publications for both the normalizing rolling, as well as the thermo-mechanical rolling, the expression “controlled rolling“ may be found. However in view of the different applicability of the products a distinction of the terms is neces
46、sary. 3.2 as-rolled delivery condition without any special rolling and/or heat treatment condition. The abbreviated form of this dlelivery condition is +AR 3.3 thermomechanical rolling rolling process in which the final deformation is carried out in a certain temperature range leading to a material
47、condition with certain properties which cannot be achieved or repeated by heat treatment alone NOTE 1 Subsequent heating above 580 oc may lower the strength values. If temperatures above 580 oc are needed reference should be made to the supplier. NOTE 2 Thermomechanical rolling leading to the delive
48、ry condition M can include processes with an increasing cooling rate with or without tempering including self-tempering but excluding direct quenching and quenching and tempering. NOTE 3 In some publications the word TMCP (Thermomechanical Control Process) is also used. 4 Classifiication and designa
