"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.

Technological properties

Application areas

It can be cold rolled and subjected to heat treatment (quenching and annealing), depending on its intended application, and is used to make mechanical parts, such as clutches, springs, segments, saw blades, measuring tape etc.

Chemical composition

The sum of the percentages by mass of the three elements chromium, nickel and molybdenum shall not exceed 0.63%.

Delivery condtion

Other dimensions may be available after prior agreement.

Heat Treatment

As this steel grade generally undergo heat treatment, a number of diagrams showing typical behaviour is available on request, such as:

  • CCT (continuous-cooling transformation) diagrams
  • Jominy curves
  • Hollomon & Jaffe curves

  • Other

    Mechanical properties:

    Since this grade will undergo re-rolling or heat treatment, we cannot guarantee its mechanical properties when delivered. Please contact the supplier for further information on this subject.

    Thickness tolerance

    In view of the tolerance values required for finished products made from narrow strip, ArcelorMittal normally offers a tighter tolerance range for these grades (half the tolerance range required by the EN 10051:2010 standard).

    Transverse coil profile

    As this product is frequently re-rolled after slitting, ArcelorMittal can supply coils with an extra flat profile (to order), which can guarantee a hot-rolled strip crown lower than 60 µm for coil thicknesses ranging from 2 to 6 mm.

    Do not hesitate to contact us.

    Internal purity

    Our steels have the degree of internal purity corresponding to the steel grade specified. It is possible to agree on the required degree of purity at the time of enquiry and order.
