Rolling stock and railway components

We serve manufacturers and shops of rolling stock and components for trains, railcars and railway equipment, where every part withstands cyclic loads, vibration and fatigue over many years of continuous service. Shafts, gears, wheels, brackets, couplers and frames need high-strength, tough materials with good response to heat treatment that ensure safety and durability. At NAT MAC we supply alloy, machinery-grade and structural steels with the required mechanical properties, in the dimensions the project needs. We complement them with cut-to-size services and technical advice to specify the right grade for fabrication, spare parts and maintenance, helping components meet safety standards and extend their service life.

Main features
Steels for cyclic loads, impact and high mechanical strength.
Transmission components, structures and parts subject to fatigue.
Forging, machining, cutting and railway fabrication processes.
