Description

MP35N™ is a trademarked grade produced by Latrobe Speciality Steel, a subsidiary of Carpenter Technology in the USA, and the trademark is owned by SPS Technologies Inc. This data sheet covers material produced for optimum corrosion resistance and to comply with the requirements of NACE MR0175. It has a face centred cubic structure matrix of cobalt and nickel, in which chromium and molybdenum are soluble at elevated temperatures. The fcc structure persists upon cooling to room temperature and below. Thereafter the combination of cold work and ageing temperature determines that the maximum CRA properties are achieved.

Technological properties

Property
Application areas

NACE material is ideally suited for oil field equipment such as fasteners, springs, non-magnetic electrical components, instrument parts, valve components, high pressure door fittings, actuators, seals, shafts and other components.

Corrosion properties

MP35N in its NACE variant offers exceptional stress corrosion cracking (SCC) resistance for harsh environments such as hydrogen sulphide, salt water and other chloride environments, as well as resists attack from mineral acids (nitric, hydrochloric and sulphur). The material has exceptional resistance to crevice and stress corrosion cracking in sea water and other hostile environments.

Processing methods

Melting: MP35N™ is produced by vacuum induction melting followed by VAC-ARC remelting to provide exceptional control of chemistry and ingot solidification.
