SUP10-CSP Alloy Strip 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 Alloy Strip 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


SUP10-CSP Alloy Strip 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 Alloy Strip 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 steel is an alloy steel formulated for primary forming into wrought products. 1.8159 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.
