Our Advantage
1. Precise thickness, uniform hardness. Bright surface, smooth edge.
2. High flatness of board surface, high performance after multiple bending.
3. No cracking after stamping, and the quality is stable. And we provide Self-Inspection Reports and Raw-Material Test Certificates.
4. Professional anti-rust protective packaging. On time delivery, competitive price.
5. Large stock available, no MOQ requirement

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.
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
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 High Carbon 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.
C67S 1.1231 alloy cold rolled narrow steel strip thicknesses up to 6mm; alloy cold rolled narrow steel strip in the quenched and tempered condition in thicknesses between 0.3 mm and 3.00 mm for springs and for other special applications.
