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. EN 10083-2, Steels for quenching and tempering - Part 2: Technical delivery conditions for non alloy steels EN 10083-3, Steels for quenching and tempering - Part 3: Technical delivery conditions for alloy steels EN 10277-1, Bright steel products - Technical delivery conditions - Part 1: General 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 10277-1 and the following apply. 3.1 steels for quenching and tempering engineering steels which because of their chemical composition are suitable for hardening and in the quenched and tempered condition have good toughness at a given tensile strength. 4 Classification and designation
4.1 Classification Steel grades C35E, C35R, C40E, C40R, C45E, C45R, C50E, C50R, C60E and C60R are non-alloy special steels. All other steel grades covered by this European Standard are alloy special steels. 4.2 Designation See EN 10277-1. 5 Information to be supplied by the purchaser See EN 10277-1. 6 Manufacturing process See EN 10277-1. SIST EN 10277-5:2008
The mechanical properties of the steels shall be as specified in Table 3, Table 4 and Table 5.
7.3 Hardenability Where steels are ordered with hardenability requirements, the requirements of EN 10083-2 shall apply for non alloyed steels and EN 10083-3 shall apply for alloyed steels.
7.4 Grain size Unless otherwise agreed at the time of ordering the grain size of non-alloy steels shall be left to the discretion of the manufacturer. If a fine grain structure is required in accordance with a reference treatment, option B.2 of EN 10277-1 shall be ordered. All alloy steels shall show an austenitic grain size of 5 or finer. Only for verification see B.2 of EN 10277-1. 7.5 Non-metallic inclusions 7.5.1 Microscopic inclusions The steels shall have a cleanness corresponding to special steel quality. For details of the requirements for the verification of non-alloy steels see EN 10083-2, A.4 for and of alloy steels see EN 10083-3, A.3. 7.5.2 Macroscopic inclusions As freedom from macroscopic inclusions cannot be guaranteed in any steel, any requirement to verify the level present shall be agreed at the time of enquiry and order (see EN 10277-1, 7.5.2 and B.3.2). 7.6 Options
