C85S 1.1269 Patented Spring Steel Strips
C85S 1.1269 Patented Spring Steel Strip
C85S 1.1269 alloy cold rolled narrow steel strip in the patented condition in thicknesses between 0.3 mm and 5.00 mm for springs and for other special applications.
Dimensions and tolerances
Thickness: 0.1 to 5 mm; Tolerances: +/- 0.008 to 0.11 mm
Width: 10 to 400 mm; Tolerances: +/- 0.15 to 0.60
*accept nonstandard size, please contact with our sales.
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

C85S 1.1269 Patented 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.
C85S 1.1269 Patented 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
C85S 1.1269 Patented 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 Quenched Tempered 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.
