C75S 1.1248 Patented Spring 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.
C75S 1.1248 Patented Spring 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.
C75S 1.1248 Patented Spring Steel Strip Mandatory information
The following information shall be supplied by the purchaser at the time of enquiry and order to enable the supplier to comply with the requirements of this European Standard:
a) the quantity to be delivered;

We hold expertise in providing a qualitative range of Patented Steel Strips to our clients at affordable prices. High carbon steel is an ideal material for custom flat springs, custom clips, and custom sheet metal stampings. High Carbon Steel Strips combines ease of fabrication with good strength and surface finish, is valued for its strength properties and operates at significantly higher levels than the mild steel grades. cold-rolled spring steel strips are gaining popularity in various industries. They are increasingly being implemented in engineering projects, through a fairly large number of small component manufacturers, parts and machine components.By making the right choice to buy steel strips, we reduce the amount of waste produced, thereby saving time and space. With a constant focus on the needs and requirements of our customers, we have created a unique offer.
Spring steel strip is used to build springs for a great variety of purposes. Below especially the cold rolled (carbon as well as stainless) spring steel strip will be described in detail. The most common production width of spring steel strip is about 300 mm (11.811 inches). As a matter of course spring steel strip can be slit or cut to length (sheets). We supply a very wide range of high carbon and alloys, covering the most stringent industrial requirements. We have also developed a unique know-how in the design of custom solutions for special applications.
75 steel - C75S - Carbon spring steel with low hardening capacity for lightweight springs for oil hardening. It is characterized by resistance to abrasion and high strength. Used for low-loaded springs and springs, spring parts, clock springs, saws for cutting stones in the form of tapes and sheets.
