DIN EN 10028-5 P355ML1 Material Machining Technology

DIN EN 10028-5 P355ML1 is a high strength, heat treatable steel grade. It is made up of iron, chromium, silicon, and other alloying elements to specifically improve its strength, toughness, and formability. Heat treatment can further enhance the steel's mechanical properties and make it more suitable for uses where high-strength and wear resistance is needed. The steel's strength is further increased when subjected to both quenching and tempering, which also improves its formability.
