51crv4 1.8159 Steel Strip Delivery condition
Cold rolled narrow steel strip covered by EN10132-4 shall be supplied in one of the following delivery conditions:
-annealed or annealed and skin passed(+A or +LC);
-cold rolled(+CR);
-quenched and tempered(+QT).
NOTE The delivery condition-annealed to achieve spheroidized carbides(+AC)-may be agreed. In such cases, limits on spheroidization and mechanical properties may also be agreed at the time of enquiry and order.
51crv4 1.8159 Steel Strip Decarburization
For silicon alloyed steels, decarburization shall not exceed 3% of the material thickness per side,for non silicon alloyed steels, decarburization shall not exceed 2% of the material thickness per side when measure data distance of 5mm from the stripe edge
51crv4 1.8159 Steel Strip Surface finish
The surface finish of cold rolled narrow steel strip shall be bright as produced by rolling and annealing in a controlled atmosphere.
The surface finishes of quenched and tempered cold rolled strip are as follows:
1 grey/blue oxide finish:unpolished;
2 brigth tempered:unpolished
3 polished: obtained by fine grinding, abrasive brushing or other processes;
4 polished and coloured:blue or yellow colour obtained by oxidization by heat
treatment.
