We hold expertise in providing a qualitative range of Blue Tempered Steel Strips to our clients at affordable prices. Owing to features like high efficiency, optimum performance and durable finish standards they are highly demanded in the market. Our ranges of these are used in various industries like automobile, cable and electronic industries. Clients can avail these strips in various dimensions with thickness as per their own requirement. We supply these at market leading prices. Known for its durability and rigidity, blue spring steel is often used in the production of clips, blades/knives, springs, coiled springs, washers, saw blades, trowels, scrapers, doctor blades for pulp mill & printing applications, spring clamps, antennas, lock picks, clock hands, grass/grain cutting tools, and brake discs.

S55C-CSP 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.
