Belt grade characteristics

Forms of supply

PCO 1320C belt grade is a dual phase carbon steel with a 75%
martensitic and 25% ferritic matrix. It is characterised by:• Very good static strength• Very good fatigue strength• Very good thermal properties• Excellent wear resistance• Good repairability

Belts are delivered, as standard, in a tempered condition andhave well-rounded edges. If required, practically any surface
finish can be supplied. Perforated belts are also available.

IPCO 1320C is a carbon steel with a hard, smooth surface anda grey oxide layer, which makes it suitable for any application
where there is a low risk of corrosion. Very good thermal
properties make it ideal for baking and similar applications.
Its low carbon content makes it possible to weld without
post-annealing.
Chemical composition (typical), %Belts are levelled and straightened to obtain optimum flatness
and straightness. They can be supplied in open lengths, withthe ends prepared for welding or riveting on site, or in theendless condition with a welded joint.
For tracking, belts can be provided with V-ropes, either rubber
or in the form of a specially designed steel spiral. If required,
the product side of the belt can be fitted with retaining strips
to keep the conveyed material in place, or with transverse
flights to prevent material from sliding backwards when thebelt is inclined steeply. Different tolerance grades are available
to ensure that the best cost alternative can be selected.

Recommendations and advice are available from your local
IPCO office.

IPCO 1320C should not be exposed to temperatures
exceeding 300 °C (572 °F) for prolonged periods (a fewhours). Material softening occurs at elevated temperatures.
We recommend that if an operating temperature ofipco.com

300 °C (572 °F) or above is considered, your local IPCO officeshould be contacted for technical assistance.
Impact strength
This belt grade is not recommended for use at lowtemperature, i.e. operating in freezing conditions.
Fatigue strength
The fatigue limit is defined as the reverse bending stressat which 50% of the test specimen withstands a minimumof 2 × 106 load cycles. These values refer to 20 °C (68 °F),a normal dry atmosphere and a standard preparedspecimen. The fatigue limit for the parent material isapproximately ± 430 MPa (62 ksi).

General corrosion
Despite its oxide layer, IPCO 1320C is susceptible to general
corrosion in aqueous solutions, especially at low pH values.
Increased temperature, flow rate, acidity and the presenceof salts increase the corrosion rate. In neutral solutions, ionssuch as CrO4-2 and NO-3 have an inhibiting effect.

Stress corrosion cracking
IPCO 1320C is not susceptible to stress corrosion cracking orintercrystalline corrosion attacks.
Hydrogen embrittlement
IPCO 1320C is susceptible to hydrogen embrittlement.
If the material is exposed to possible sources of hydrogen
embrittlement, a special heat treatment is recommended.
Contact your local IPCO office for information.

Joints with very good strength and toughness can be formed inIPCO 1320C. A suitable fusion welding method is gas-shieldedarc welding, with the TIG method as first choice.

If welding wire is used, type should be 1320C. Further
information concerning method and equipment etc. required
can be obtained from your local IPCO office.

IPCO 1320C has high thermal conductivity and low thermal
expansion, which makes it less sensitive to buckling andthermal strain caused by uneven temperatures.
