MP35N

Descriptions of MP35N

MP35N (UNS R30035) is an austenitic Ni-Co-Cr-Mo alloy with a unique high mechanical strength, associated with very high corrosion resistance. It is able to resist stress-corrosion and harsh environments which often leads to its selection as a fastener or spring material.MP35N resists corrosion in hydrogen sulfide, saltwater, and other chloride solutions. Due to these properties, it is often selected as components and parts for marine environments like, for instance, cables that conduct sensors for measurements in the deep ocean. It is also used in the automotive and aerospace industries.
