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.

1. Stable linearity, good formability. Uniform and beautiful surface condition.
2. High plasticity and good fatigue resistance. And we provide Self-Inspection Reports and Raw-Material Test Certificates.
3. Professional anti-rust protective packaging. On time delivery, competitive price.
4. Large stock available, no MOQ requirement.
Soft Annealing:
Heat to 640-680C, cool slowly in furnace. This will produce a maximum Brinell hardness of 310.
Normalizing:
Temperature: 850-880C, air.
Hardening:
Harden from a temperature of 840-870C followed by oil quenching.
Tempering:
Tempering temperature: 430-500C, air.
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.
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.
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.
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.
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.
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.
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.
