BS DIN EN 54SiCr6 1.7102 Round Alloy Steel Wire for Spring Application

What is 54SiCr6

54SiCr6 1.7102 steel is an alloy steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 54SiCr6 1.7102 is the designation in both the DIN and EN systems for this material. 54SiCr6 is a Standard grade Alloy Steel. It is commonly called 54SiCr6 Silicon-manganese steel. It is composed of (in weight percentage) 0.51-0.59% Carbon (C), 0.60-0.80% Manganese (Mn), 0.035%(max) Phosphorus (P), 0.04%(max) Sulfur (S), 1.20-1.60% Silicon (Si), 0.60-0.80% Chromium (Cr), and the base metal Iron (Fe). Other designations of 1.7102 alloy steel include UNS G92540 and AISI 9254.

Information to be supplied by the purchaser

The purchaser shall clearly state in his enquiry or order the product and following information :

a)the desired quantity;

b)the number of this European Standard: EN 10270-2;

c)wire grade

d)the nominal wire diameter;

e)the form of delivery and unit mass;

f)the type of inspection document;

g)any particular agreement made.

54SiCr6 Form of delivery

Oil hardened and tempered wire shall be supplied in coils, on spools or in cut lengths. The wire in coils or on spools shall form one continuous length. Wire in coil may also be supplied on carriers containing one or more coils.

For VD and TD grades no welds are permitted after the heat treatments preceding the final drawing operation; for 'FD' grades no welds shall be made at finished size unless agreed otherwise between the parties.

The supplied wire units shall be tightly bound to ensure that wire spiral waps do not spring out unforeseen. The starting end shall be marked and at the coil ends the wire shall be covered with a protective cap.

54SiCr6 Non metallic inclusions

The VD grades shall be checked for maximum size of inclusion according to ENV 10247. The allowable level of inclusions shall be agreed between the parties at the enquiry and order.

54SiCr6 Surface quality

The surface of the wire shall be smooth and permissible depth of surface defects at the coil ends shall be in accordance with 0.005-0.015d.

By in-line control of surface defects the areas of the coil with defects above the level of 40-60μm shall be marked. In-line testing is not performed for FD-grades.

The number of defective parts that can be tolerated may be agreed between the parties.

54SiCr6 Surface decarburization

The wire grades according to this standard shall be free from total decarburization. The maximum depths of the partially decarburized zone shall be checked at the end of the coils.

54SiCr6 Out of roundness

The out of roundness, i.e. the difference between the maximum and minimum diameter of the wire at the same cross section, shall not be more than 50 % of the total permissible deviation specified.

54SiCr6 Marking and packaging

Each unit shall be properly marked and identified so as to permit traceability and reference to the inspection documents.

The labels shall withstand normal handling and contact with oil; they shall show at least the information according to standard. Other information shall be subject to an arrangement between the parties.

Wire shipments shall be suitably protected against mechanical damage and/or contamination during transport.

Our spring steel wire comes in various categories such as music wire, hard drawn wire, oil tempered wire, chrome silicon wire, chrome vanadium wire, stainless steel wire, nickel plated wire, phosphate coated wire, galvanized wire, and copper coated wire.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
