CHROME -MOLYBDENUM
NI-HARD IRON CASTINGS
GJN (UNI EN 12513)

CHROME-MOLYBDENUM ALLOYS
They are alloys containing Cr 16-26% and  Mo 0.5-2.5% with a martensitic structure containing complex FeCr carbides and a Brinell hardness of 650-830 HB depending on the heat treatment done.

NI-HARD IRON CASTINGS
They are martensitic/austenitic-martensitic white iron castings  with complex FeCr carbides and a Brinell hardness between 480-750 HB depending on the heat treatment done.

COLCHROME ALLOYS
In addition, we produce the following out of standard wear-resistant alloys of our concept  which offer a perfect compromise between cost/wear resistance where a high wear resistance is not required:

Colchrome Plus: Martensitic alloy improved with chrome carbides (Cr 8-9%, Mo 0.3%) and a Brinell hardness of 650-700 HB.
Colchrome:Martensitic alloy improved with chrome carbides (Cr 8-9%, Mo 0.3% max) with isolated perlitic areas and a Brinell hardness of  580-620 HB.
Colchrome Standard: Low-alloyed white iron with chrome carbide islands (Cr 2% max) and a Brinell hardness of 480-520 HB.

APPLICATIONS

Wear resistant castings for coal and ore grinding mills and abrasion resistant castings
(liner plates, grinding tracks, rollers and balls, elbows, connections and fittings for lines conveying abrasive materials)

Wear resistant castings for bitumen and concrete production plants
(liner plates for bitumen and concrete mixers and cement pumps)

  Wear resistant castings for the crushing and grinding industry even in presence of low level hits 
(hammer and plates for crashers, liner plates for ball mills, segments for pulp refining, etc.)

Castings for sand and shot-blasting equipment
(plates, blades, safety guards, batching components, accelerators, tables, etc.)

Filters for Biomass boilers
  (air separators and cyclons)

GREY AND DUCTILE IRON CASTINGS 
GJL (UNI EN 1561) and GJS (UNI EN 1563)

GREY IRON CASTINGS
Grey iron castings with lamellar graphite and ferritic-perlitic structure according to the requested type.
Castings to be used in the mechanical field for different applications.

DUCTILE IRON CASTINGS WITH NODULAR GRAPHITE
Ductile iron castings with nodular graphite and ferritic- perlitic structure to be used in applications where high mechanical properties like tensile strength, yield stress, impact test and elongation are required.

APPLICATIONS

Castings for gas and steam thermoelectric power plants 
(blade carriers, medium and low pressure fix diaphragms for steam turbines, bearing pedestals, pressure retaining castings)

Castings for mechanical industries, for machine tools and plastic processing equipment

Castings for power wind turbines
 (house bearings, blade hubs, yaw tops and other smaller castings)

Induction hardenable and pressure retaining castings
(machine beds, tables, uprights, saddles, heads, pumps, etc.)

AUSTENITIC LAMELLAR AND DUCTILE
NI-RESIST IRON CASTINGS
GJLA and GJSA (UNI EN 13835) 

Austenitic iron casting with high nickel content, 16-35%.
This iron casting provides good resistance to mineral acids and sea water, in addition to heat resistance. This iron casting is also non-magnetic.

APPLICATIONS

Castings for petrochemical industry, gas and steam thermoelectric power plants (stationary blade carriers, pressure retaining castings, pump casing, valves, etc.)

GJS SiMO (UNI EN 16124)

Ferritic ductile iron alloyed with Silicium and Molibdenum with an improved resistance to high temperatures and thermal heads.

APPLICATIONS

Used in the gas-turbine field

OUT OF STANDARD
HEAT-RESISTANT ALLOYS

Lamellar ferritic iron castings with C 1.2% and Cr 33%

APPLICATIONS
