This European Standard EN 10277, Bright steel products Technical delivery conditions, is subdivided as follows: Part 1: General; Part 2: Steels for
18、general engineering purposes; Part 3: Free-cutting steels; Part 4: Case-hardening steels; Part 5: Steels for quenching and tempering. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Aust

24、 Technical delivery conditions Part 1: General. 3 Definitions For the purpose of this standard, the following definition applies in addition to the definitions in EN 10277-1. 3.1 steels for quenching and tempering engineering steels which because of their chemical composition are suitable for harden
25、ing 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
26、 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. 7 Requirements 7.1 Chemical composition 7.1.1 Cast analysis The chemical composition of the steel according to the cast analysis s
