C 80 annealed Steel stripe – A High Carbon Steel

This is the most appreciated of all grade of Steel popularly known as spring still stripe annealed, it is high carbon steel strip, or cold rolled Steel strip,

This grade C-80 of Steel can be named in many types of Steel as high carbon steel strip, cold rolled Steel strip, spring Steel strip and unhardened.

Well introducing it as a high carbon cold rolled Steel strip, with shpherodized grain structure. In nature it is high yield strength steel. These features are helping this type of Steel cold rolled to resume its original shape, despite bending or twisting before hardening and tempering processes.

We are quality supplier of this type of Steel in the soft and annealed condition, but the same can be supplied with temper rolled hardness range 200 _350 HP.

Our C-80 stripes are made up of excellent raw material and high grade of stainless steel obtain from the best sources in the market available. It is to be learnt that it possesses, good forming and blanking properties, but on the other hand when it comes to drawing properties the performance of it is very poor.

The things to take away for a visionary business is that this grade of steel is also called spring still strike annealed, unhardened, and carbon steel type and cold rolled Steel strip in general.

We at Steel Corporation of India are offering this type C 80 steel stripes in various technical specification which are also created to be costumed design in order to meet the various demand of clients.

Physical properties of C 80 annealed Steel stripes
Surface is free bright without any detrimental surface defects
Hardness in annealed condition 200Hv max
Yield Strength N/ MM2 Max
Edge are prominent, proper and clean slit  


Properties of C55 grade cold rolled annealed steel strips / Chemical composition by weight
Carbon 0.75 - 0.85%
Manganese 0.60 - 0.90%
Silicon 0.0-0.35%
Sulphur 0.025%
Phosphorous 0.025%

This grade is similar to 80c6 of IS2507 of 1975 & C1080

Physical properties

  • Hardness is annealed condition 200Hv Max
  • Yield strength 290 N/MM2
  • Elongation 25% Minimum
  • Tensile strength 640N/mm2
  • Surface bright and free from any detrimental surface defect

Bend Test: Strips shall pass bend test as recommended below

  • • Bend test When bending maintain radius as follows :
  • Grain Wise Against Grains
    For thickness 4.00 mm to 2.50 mm r=2t not advised
    For thickness 2.30 mm to 1.20 mm r=1t not advised
    For thickness 1.0 mm to 0.50 mm r=0t r=1t
    For thickness 0.45 mm to 0.20 mm r=0t r=0r

    'r' stands for radius of bend and 't' for thickness of strip. Other Properties
