Product Description

Product Description
Introduction MP35N is an age hardenable Nickel-Cobalt base alloy that has a unique combination of properties - ultra high strength, toughness, ductility and outstanding corrosion resistance. MP35N resists corrosion in hydrogen sulphide, salt water and other chloride solutions. It also has excellent resistance to crevice and stress corrosion cracking in sea water and other hostile environments.
The four alloy elements in MP35N are the basis for corrosion resistance in almost every Stainless Steel, Nickel and Cobalt-based alloy commonly used in the industry. The alloy resists corrosion in hydrogen sulphide, salt water and other Chloride solutions, as well as the mineral acids (Nitric, Hydrochloric and Sulphuric).
MP35N is suitable where a high combination of strength, high modulus values and good corrosion resistance are required.
Applications for this alloy also include medical devices and dental products.

Heat Treatment (Aging)
MP35N should be aged at the temperature required to achieve the final properties desired. The amount of cold work in MP35N defines the recommended aging treatments. For AMS 5844 (fully strength/heavily cold worked) material, the alloy should be ages at 1000ºF - 1200ºF for 4 hours. For optimum sulphide SCC resistance, less-heavily cold worked material can be aged at 1300ºF or 1350ºF for 4 hours or at 1425ºF for 6 hours as indicated in NACE MR-0175. The 425ºF aging treatment provides the best sulphide SCC resistance, but at the expense of strength. Exposure to temperatures much above the recommended aging temperatures may result in significant (and nonrecoverable) loss in strength cause by the reversion of the cold-worked metallurgical structure to the much softer annealed structure.
