AISI 4340 powder for metal injection moulding
4340 steel is a high-strength alloy steel known for its excellent mechanical properties, including high strength, toughness, and fatigue resistance. It contains higher carbon (0.38-0.43%) and chromium (1.65-2.00%) content, along with smaller amounts of manganese, silicon, and molybdenum. This alloy is widely used in applications that require parts with high strength and good toughness.
