Introduction to the hardest stainless steel to CNC Machining … Super Duplex 2507 is a high-performance stainless steel alloy classified as a "super duplex" due to its exceptional strength and corrosion resistance. It is composed of approximately 25% chromium, 4% molybdenum, and 7% nickel, with additional elements like nitrogen enhancing its properties. This alloy features a dual-phase microstructure, combining roughly equal parts of austenite and ferrite, which gives it a unique blend of characteristics from both types of stainless steel.
