NOTE 2 Hammer forged semi-finished products blooms, billets, slabs etc. NOTE 3 Special agreements should be made when ordering un-worked continuously cast semi-finished products. The differences between quality and special steels are characterized by the following requirements, which are valid for special steels only: the minimum impact values in the quenched and tempered condition for non alloy special steels in the case of.

Ruling sections for the mechanical properties Other relevant standards Dimensional standards applicable to products complying with this European Standard Determining the non-metallic inclusion content This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February , and conflicting national standards shall be withdrawn at the latest by February For bright steel products.

EN and EN apply. In special cases, variations in these technical delivery requirements or additions to them may be agreed at the time of enquiry and order see Annex B. In addition to the specifications of this European Standard, the general technical delivery conditions given in EN are applicable unless otherwise specified. EN E 5 2 Normative references The following referenced documents are indispensable for the application of this document.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies. Independent of the actual shape and dimensions of the cross-section of the product the size of its ruling section is always given by a diameter. This corresponds to the diameter of an "equivalent round bar".

That is, a round bar, which, at the position of its cross-section specified for taking the test pieces for the mechanical tests, will, when being cooled from austenitizing temperature, show the same cooling rate as the actual ruling section of the product concerned at its position for taking the test pieces 4 Classification and designation 4.

If the purchaser does not indicate his wish to implement any of these options, the supplier shall act in accordance with the basic specification of this European Standard see 5.

NOTE Depending on product shape and dimensions, not all steel grades can be delivered in the hot worked untreated condition. EN E 9 7 Requirements 7. EN or EN respectively. The product analysis shall be carried out when specified at the time of the order see B.

EN shall apply. The mechanical property values given in EN and EN apply to test pieces in the quenched and tempered or normalized condition which have been taken and prepared in accordance with Figure 1 or Figures 2 and 3.

Ca treatment. Regarding the verification of non-metallic inclusion content of special steels see B. NOTE Segregation is the result of a natural phenomenon. Segregations can be found in ingots as well as in slabs, blooms and billets from the continuous casting process.

The positive segregation is a concentration of various elements at different locations in the ingot, slab, bloom and billet. In case of flat products customers should note, that these segregations can occur parallel to the surface of the product. Especially for medium and high carbon contents segregations lead to a higher hardness and should be taken into consideration during further heat treatments.

EN E 10 7. EN specifies requirements of ultrasonic testing of flat products of thickness equal to or greater than 6 mm and EN specifies requirements of ultrasonic testing of steel bars see B. Bars and rods shall be delivered with surface class A according to EN unless otherwise agreed at the time of enquiry and order. NOTE 2 It is more difficult to detect and eliminate surface discontinuities from coiled products than from cut lengths. This should be taken into account when agreements on surface quality are made.

The depth of decarburization shall be determined in accordance with the micrographic method specified in. EN ISO If surface discontinuities are repaired, the method and maximum depth of removal shall be agreed at the time of enquiry and order. The type of document shall be agreed upon at. EN E 11 the time of enquiry and order. If the order does not contain any specification of this type, a test report shall be issued. EN for the steel grade concerned. In addition, the inspection certificate shall contain the following information: a the manufacturer's results for the cast analysis of all elements specified in the Tables 3 of.

EN E 12 9 Preparation of samples and test pieces 9. For hammer and drop forgings the test pieces shall be taken with their longitudinal axis parallel to the direction of principal grain flow from a position to be agreed at the time of enquiry and order.

Test pieces may be non-proportional but in cases of dispute proportional test pieces having a gauge length. EN shall be agreed at the time of enquiry and order. This document specifies the technical delivery requirements for — semi-finished products, hot formed, e. The s This document specifies technical delivery requirements for the surface quality of round bars, squares, hexagons and wire rod in the hot rolled condition with nominal dimensions dN from 5 mm to mm.

This document is applicable to bright products and tool steels, if agreed at the time of enquiry and order between manufacturer and purchaser. By agreement between manufacturer and purchaser, this document can also be applied to other special profiles. This document is particularly applicable to This document specifies requirements for the following grades of wrought tool steels: a non-alloy cold-work tool steels; b alloy cold-work tool steels; c alloy hot-work tool steels; d high-speed tool steels.

If not stated otherwise, this document applies to all types of hot-rolled, forged, cold-drawn or cold-rolled products or products produced by powder metallurgy, which are supplied in one of the surface and heat-treatment conditions given in 6. NOTE Tables 2, 4, 6 and ISO specifies the technical delivery requirements for - semi-finished products, hot formed, e. The bright bars are subdivided into the following steel types: a non-alloy general engineering steels; b non-alloy free-cutting steels; c non-alloy and alloy case-hardening steels; d non-alloy and alloy steels for quenching and tempering.

This document lists the mechanical character ISO gives the technical delivery requirements for semi-finished products e. It covers three groups of free-cutting steels for mechanical purposes as listed in Table 2, namely a not intended for heat treatment, b suitable for case-hardening, and c suitable for They are manufactured from the direct hardening non alloy steels for quenching and tempering and the direct hardening alloy steels for quenching and tempering and supplied in one of the heat treatment conditions given for the different types of products in Tabl TC - Table 3 - Change of values.

If you specify, purchase or supply steel, BS EN has been developed by technical experts as an invaluable to guide to the standard purchase specifications and delivery conditions of semi-finished, hot formed products such as:. The standard does not cover bright steel products see BS EN series or continuously cast semi-finished products for which special arrangements must be made. BS EN concentrates on the general supply conditions; the detailed specifications of the steels themselves being defined in part 2 non-alloy steels and part 3 alloy steels. The steels are generally intended for the manufacture of quenched and tempered, flame or induction hardened machine parts, but alternatively may be supplied in the normalized condition.
