Product Information
Fushun Metal offers a wide variety of spring steel products to meet your specifications. Spring steel refers to steel, normally of the high carbon or alloy type, used in the manufacture of springs. the steel is processed by cold drawing, cold rolling, or heat treating to give it the elastic properties and yield strength required in springs.

Spring steel is often used because of its high yield strengths, resistance to deformation, and its ability to return to its
Original shape. Our spring steel and spring steel strips are available as heat-treatable annealed, which allows the forming to occur prior to the heat treatment, or heat treated, where the steel is previously hardened, tempered, or sprung. Our inventory of annealed spring steel can be easily formed, tempered, heat treated, blanked or shaped.


1.8159 Steel Description
1.8159 is a heat treatable,low alloy steel containing manganese,chromium and
Vanadium.It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength.

1.8159 Steel Applications
Permanently stressed machine,engine and vehicle parts when high strength and toughness are required.most severely stressed springs for trucks,torsion springs.

1.8159 STEEL HEAT TREATMENT:
* FORGING:Preheat carefully, then raise temperature to 1050°C for forging. Do not forge below 840°C. after forging cool slowly in a furnace.
* ANNEALING:Heat slowly to 820-840°C, soak well and cool slowly in a furnace.
* HARDENING:Heat slowly to 650-700°C and thoroughly soak. Continue to heat the 6150 steel to the final hardening temperature of 830-860°C and allow to be heated through. Oil quench.
* TEMPERING:Temper 6150 spring steel immediately after hardening whilst tools are still hand warm. Re-heat to the tempering temperature then soak for one hour per 25 millimetre of total thickness (2 hours minimum) Cool in air. Tempering of this grade will be between 400-600°C for most applications

Machinability
Machining is best done with this alloy in the annealed or normalized and tempered condition.It can be machined by all conventional methods.

Corrosion Resistance
this is a low alloy steel and not a corrosion resistant alloy.Protective coating should be used.

Welding
the alloy can be fusion or resistance welded.Preheat and post heat weld procedures should be followed when welding this alloy by established methods.

Cold working
the alloy may be cold worked,in the annealed condition,by conventional methods and tooling.It has good ductility.

Mills test certificate:
EN 10204/3.1 with all relevant data reg. chem. Composition, mech. Properties and results of testing.


We stock a wide range of grades from annealed CS70, through CS80, CS95 and CS100 in the hardened and tempered condition. We also stock 301 stainless spring steel and 420 blade steel.
