S50C-CSP 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.


S50C-CSP Blue Steel Strips Delivery condition

Cold rolled narrow steel strip covered by JIS G4802 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.


S50C-CSP 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.


S50C-CSP properties and heat treatment, Including S50C-CSP application and specifications, We have all specifications,Including S50C-CSP steel plate, S50C-CSP sheet, we can own production and sales. One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength. Whether its for wear parts, springs, chain links or safety components, heat treatable steels offer the right solution for all requirements. Good fine blanking properties and formability in the annealed condition are combined with high strengths and good toughness in the quenched and tempered condition. Close analysis ranges tailored to specific purposes and precisely controlled rolling parameters guarantee consistent and outstanding processability and consistent heat treatment results.
