51CrV4 1.8159 Quenched Tempered Strip 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.
51CrV4 1.8159 Quenched Tempered 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.
Hardened and Tempered Steel Strip (also known as hardened and
tempered High carbon steel strip or, hardened and tempered carbon
spring steel strip) is the basic raw material from which many
different components are made, substantially being spring-type
applications ranging from clutch plate segments to washers,
retractor springs and even to tree springs in riding saddles and
traditional clock springs. These strip products are a specialty of
the Company and considerable plant development has taken place in
recent years to facilitate a very wide range of dimensions,
mechanical properties and coil weights. Hardened and Tempered Steel
Strip gauges of between 0.10mm and 2.00mm can be processed and,
depending on the appropriate combination to suit the process
equipment, strip widths of between 4.76mm to 240mm are produced.
The facilities also allow up to 2000kg coils to be produced though
most are well below this, being governed by a very approximate
relationship of 100kg per 25mm of width.
The surface finish of Hardened and Tempered Steel Strip products is
not too critical in general engineering applications where the
normal blue-black (also known as blue-grey) oxidized finish from
the heat treatment is satisfactory. By control of the atmospheres
in the furnaces non-oxidised surfaces can also be produced, on a
selected basis, and alternatively, steels can be satin or bright
polished were needed, these finishes being as much for cosmetic
reasons as for engineering purposes.
EN 1.8159 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.

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.
