MATERIALS OF CONSTRUCTION

• Grey iron
• Ductile iron
• Special alloy cast iron SPIRO-HARD (intended for thermal treatment to achieve high abrasion resistance)

Stainless steels are used wherever resistance to aggressive media is required. However, different types of stainless steel provide other advantageous properties that are required in some specific applications. (AISI304/L, AISI316/L, 316Ti)

Duplex steels combine the advantages of ferritic and austenitic stainless steel. They have increased resistance to aggressive media and also more advantageous mechanical properties therefore they are often used in the most demanding industrial applications. (A890, 329, ...)

Nickel is almost completely resistant to dilute acids due to its ability to form a protective coat on its surface in the oxidation phase when getting into contact with the acid for the first time. Nickel-based alloys excellently resist aggressive media and they are highly chemically stable. Thanks to their specific properties, these alloys are often used in the chemical industry. (C-22, C-4, B-2/3, C-276...)

Titanium and titanium alloys are suitable for media and environments with a very high oxidation rate and high chloride content, for example in desalinization plants.
