Cutting-edge technology allows AST to offer a vast range of steel for the transport sector (buses, trains, subways, lorries, vans, etc.) In the railway industry, for example, AST has developed new solutions in lighter weight steel for freight wagons. The mechanical resistance of special grades of stainless steel results in reduced gauges with a consequent reduction in the vehicle weight and lower fuel consumption. AST stainless steel is also widely used in structural contexts, for example, in bus frames. Other notable advantages are the easy workability and the high mechanical resistance which results in a reduction in the overall weight and high resistance to corrosion due to the self-passivation feature of steel when damaged.
