C100S 1.1274 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.


C100S 1.1274 Blue Steel Strips 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.


C100S 1.1274 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

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.


Steel C100S (1.1274) - specification and application: C100S is Low-alloy carbon steel for thermal improvement by oil hardening available in strips and thin cold-rolled sheets used for springs and leaf springs with small cross-sections. It is characterized by low hardenability, abrasion resistance and decarburization and oxidation tendency during heat treatment.C100S steel products and its equivalents do not show resistance to atmospheric corrosion, and after heat treatment get tempered martensite structure. Carbon spring steels are delivered in various hardening and soft condition variants.Steel used for spring washers, spring elements, feeler gauges, and other loaded parts requiring high elasticity and tensile strength.

The steel C100S is used as cold rolled strip for springs and special applications in thicknesses of up to 6 mm and as tempered cold strip in thicknesses from 0.30 to 3.00 mm. The springs made of steel C100S are suitable for highly stressed tension springs, especially in the watch industry, as well as for pen nibs.
