MP35N® Alloy, with its nickel-cobalt-chromium-molybdenum content, has a special combination of high strength, ductility and corrosion resistance. In the annealed state, it has the same easy-to-work characteristics of the 300 series alloys, yet it is capable of being hardened by a simple heat treatment. It has higher tensile strength/hardness and even ductility compared to the 300 series when cold-worked. After the aging heat treatment, it has one of the highest strengths on any currently produced alloys. The unique properties of MP35N® allow for it to be used in applications where other alloys have failed.

K-Tube has the capability to make tubing with the wall thickness and outside diameter combinations in the chart below. Tubing with an OD/Wall ratio lower than 20:1 can be drawn to the final dimensions. Tubing with an OD/Wall ratio between 20:1 and 40:1 must be centerless ground to the final dimensions. K-Tube's capabilities are constantly improving, please inquire if your dimensions are outside of the listed dimensions.
