C90S 1.1217 Blue Steel Strips Delivery condition
Cold rolled narrow steel strip covered by EN10132-4 shall be supplied in one of the following delivery conditions:
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.
C90S 1.1217 Blue Steel Strips 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
C90S 1.1217 Blue Steel Strips 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.

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.
high carbon steel blue tempered spring steel strip is harder, less bendable, and has a higher degree of spring back. Finished products made from this material have better edge retention, which correlates to the material's other properties. blue spring steel strip is used widely in the manufacture of springs, prominently in automotive and industrial suspension applications. It is a high carbon steel with a very high yield strength. This material allows objects made of spring steel to return to their original shape despite significant deflection or twisting.
C90s, 1.1217, 95cr1, 1.2018 - low-alloy spring steel with high carbon content for heat treatment - oil hardening according to en 10132-4 and en 10270-1. Spring construction steel for oil hardening for springs and working periodically springs with small dimensions.
Provided in the form of a spring tapes - C90S is characterized by high abrasion resistance and high strength.In addition to the use for springs, it is also designed for wood and stone saws, knives and machine scissors, spring washers, cutting elements and cutting tools. After the treatment shows the structure of tempered martensite. During heat treatment, a protective atmosphere should be used to avoid decarburization and oxidation of the material.C90S steel has a higher carbon content than C67S, C55S and C75S.
