Cast irons with a basic structure composed of austenite. These are highly alloyed cast irons designed for use in extreme conditions unsuitable for other types of materials. Each type of these cast irons guarantees specific properties such as corrosion resistance in aggressive environments, heat resistance, fire resistance, abrasion resistance, non-magnetism, sliding properties, etc.
