Alloys

Carbon steel is a steel with carbon content (between 0.12 and 0.5%). It includes only a very small amount of other alloying elements. This type of steel is very strong and impact resistant. It is also an environmentally friendly solution as it can be more easily recycled than other metals.

Carbon steel generally contains less than 10% alloying elements, with no element exceeding 5%. According to its components and thermal or thermomechanical treatments, this type of steel can be modified to increase its hardness, breaking load, resistance to wear, creep or corrosion, or another characteristic specific to its use.

Stainless steel is a ferrous alloy that contains over 50% iron and a minimum of 10.5% chromium. All stainless steel has impressive corrosion resistance, making them essential alloys for the construction industry. Stainless steel alloys are also non-magnetic (therefore without magnetic property) and have high mechanical strength.

From the family of austeno-ferritic steel, duplex steels are stainless steels with a two-phase structure composed of ferrite and austenite. This type of stainless steel is particularly resistant to corrosion, even in environments rich in chlorine or sulphites. Its properties make it an alloy of choice for the storage and transportation of chemicals, for gas and oil pipelines, for mineral and gas exploration and for refineries.

This type of cast iron is obtained by a low casting temperature, rapid cooling, a high content of pearlitizing elements (ex: manganese, copper, etc.) or a low content of graphitizing elements (ex: silicon)1.  White castings are made of perlite and ledeburite
