Standard

EN 10277-1 Bright Steel Products Technical delivery Condition.






These standards cover bright stainless steel bars in drawing, turned or ground conditions. They do not cover cold rolled products and cut lengths from strip or sheet produced by cutting

Drawn products:
These are products of various cross section shapes which are obtained after descaling, by drawing of hot rolled bar or rod on a draw bench. This involves cold deformation without removing material. This operation gives the product special features with respect to shape, dimensional accuracy (BS ISO 286 IT11 or better) and surface finish. This process results in cold working on the material.

Turned products
Round bar produced by turning on a lathe of Cold Drawn steel (Turning Hot rolled steel is not part of this standard). The turning removes surface defects and carburisation.

Ground /Polished Bar
Cold Drawn and/or Turned bar is ground or polished to improve the surface quality and dimensional accuracy.

This steel is classified in accordance with EN 10020 and identified in accordance with the relevant Standard EN 10277 parts 2-5. The steel designation is in accordance with EN 10027 -1 and the number is in accordance with EN 10027-2




In accordance with this standard the primary information to be supplied by the purchases includes the following...

a) The quantity to be delivered (mass/number of bars) . e.g. 2t
b) The product shape (round, square, hexagon, flat ) e.g. round
c) The dimensional Standard e.g BS EN 10278
d) The dimensions and tolerances e.g 20mm dia , tolerance h9, stock length 6 000mm
e) Reference to European Standard e.g BS EN 10277-3
f) Steel name -in accordance with BS EN 10027-1 (chemical composition) or number in accordance with BS EN 10027-2. e.g. 38SMn28 (1.0760)
(0.38% Carbon, 0,28% Sulphur - average %'s) or 1.7021
g) Delivery condition e.g +C
h) Class of surface quality e.g class 3

Optional information which may be provided includes, reference testing for products used in the quenched and tempered condition (see B.1); any fine grain requirement and verification requirement for the verification of non-metallic inclusions: depth of decarburization
additional requirements to the tolerances on shape according to EN 10278:
temporary corrosion protection :
non-destructive testing :
product analysis :
special marking :
hardenability requirements for grades of EN 10277-4 and EN 10277-5 and EN 10277-5);
type of inspection document in accordance with EN 10204 (see 8.1).

Details of these optional features are provided in the Standard.

Example...
2 t, round bar, BS EN 10278-20 h9 x stock 6,000
BS EN 10277-3, 38Smn28 +C-class 3
