7.3 Hardenability
EN 10277-1, Bright steel products Ð Technical delivery conditions Ð Part 1: General .
Where steels are ordered with hardenability requirements, the requirements of EN 10084 shall apply.
EURONORM 1031), Microscopic determination of the ferriti fer riticc or austeni austenitic tic grain grain size size of stee steels ls.
7.4 Grain size
3 Definitions For the purpose of this standard, the following definition applies in addition to the definitions in EN 10277-1.
Unless otherwise agreed, the steel when tested in accordance with one of the methods described in EURONORM 103 shall show an austenitic grain size of 5 to 8. The grain structure shall be considered satisfactory if 70 % of the area is within the specified size limits. For verification see EN 10277-1, B.2 10277-1, B.2..
3.1 3.1 case-hardening steels
7.5 Non-metallic inclusions
steels with a relatively low carbon content, which are intended for carburizing or carbonitriding and subsequent hardening. Such steels, after treatment, are characterized by a high hardness surface layer and a tough core
The steels shall have a degree of cleanness corresponding to the special steel quality.
For details of requirements and verification see A.1 see A.1 and annex D of EN 10084:1998. 7.6 Supplementary or special requirements See annex B of EN 10277-1.
Steel grades C10R, C15R and C16R 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.
9 Marking See EN 10277-1.
5 Information to be supplied by the purchaser See EN 10277-1.
It may be agreed at the time of ordering, until this EURONORM has been adopted as a European Standard, that either this EURONORM or a corresponding national standard should be applied.
