SUP10-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.
SUP10-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.
SUP10-CSP Blue Steel Strips 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;
b) the designation of the product form (cold rolled narrow strip);
c) the number of the dimensional standard ;
d) the dimensions and tolerances on dimensions and shape and, if applicable, letters
denoting relevant special tolerances;
e) the number of this European Standard including the number of the relevant part;
f) steel name or steel number
g) the delivery condition
h) if required, the type of inspection document in accordance with JIS G4802
SUP10-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
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. High carbon steel strip can be finished to meet the needs of a wide range of products. Where tensile strength and hardness are required, High Carbon steels are the material of choice. High Carbon Steel Strips Grades : C60, C65, C70, C75, C85, HC-14, En 42 J, C-98, C-100, C-124, HC21 etc. We offer spring steel strip in various shapes and sizes according to your final uses. These have excellent hardens property and high yield strength. Clients can avail these at competitive prices.
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.
SUP10-CSP steel is an alloy steel formulated for primary forming into wrought products. SUP10-CSP is the EN numeric designation for this material. 51CrV4 is the EN chemical designation. It has a moderately low melting temperature and a fairly high embodied energy among EN wrought alloy steels.
The steel, unlike other carbon and alloy grades, is characterized by high hardness, low vulnerability to tempering, resistance for variable and heavy loads, and the ability to operate at elevated temperatures up to 300 ℃. Surface-hardened, retains excellent strength properties of the core while maintaining sufficient surface hardness.58CrV4 / 1.8161 and 59CrV4 / 1.2242 are related grades with the same range of alloying additives. It is distinguished by the higher carbon content, which makes it possible to achieve even higher hardness after heat treatment.51CrV4 / 50CrV4 / 58CrV4 / 59CrV4 grades are supplied as hot-rolled bars, drawn bars, wires, spring stripes, forgings are used for the production of heavy-duty springs, axles, crankshafts, connecting rods, compression springs, valve springs, springs, shock absorbers or spring washers.It is mainly supplied in an annealed, softened, heat-treated and raw conditions. Steel does not exhibit corrosion resistance, so products should be protected with greases or coatings.
