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.
In annealed and lightly rolled materials, they exhibit a large
degree of elongation, and can withstand complex processing. Springs
are used in plenty of applications in the present-day world. Even
so, only a few people have a nodding acquaintance with the brass
tracks of spring manufacturing and the different qualities needed
for various functions. While coiling steel into a spiral of desired
length and diameter is the primary and center-most stage of spring
fabrication, other treatments during and after the procedure
determine the quality of the product that reaches the consumer.
51CrV4 1.8159 Annealed 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 Annealed 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. Annealed 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.
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.
