Applications
• Gun barrels for firearms when a balance between ultimate tensile strength (UTS) and Impact Toughness (KV) at -40°C is above standard used steel grade and good wear erosion.
• For any safety mechanical application for which a balance between strength and impact toughness is needed expecially at low temperatures.
Mechanical properties
• Very good ability to cold hammering and button rifling.
• Opportunity to heat treat above 40 HRC, while maintaining a high level of Charpy Impact Toughness at 20°C and -40°C, enhancing firearm performances in operation.
