We Introduce Multi-Phase Alloy MP35N™ As Part Of Our Stock Range

Broder Metals Group Ltd are pleased to announce another addition to our Oil & Gas bar stock range with the introduction of grade MP35N. This is a nickel-cobalt alloy only manufactured by Latrobe in the US and provides a unique combination of properties including ultra high strength, toughness, ductility, and outstanding corrosion resistance. The high strength variant of MP35N™ is used in the medical and aerospace industry while material produced for the oil and gas applications has less cold work reduction than the full strength variant to give the material better stress corrosion cracking (SCC) resistance for harsh environments, and in order to conform to NACE MR0175 / ISO 15166-3 (2009). In this condition the material resists corrosion in 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. The amount of cold work defines at what temperature the material is aged to achieve the final properties required. Typically for optimum sulphide stress corrosion cracking(SCC) resistance the material is aged at 1300 / 1350 deg F for 4 hours (more strength / slightly less SCC resistance) or at 1425 deg F for 6 hours (better SCC resistance / less strength). The material is suitable for use in the manufacture of fasteners, springs, non-magnetic electrical components, instrument parts, valve components, high pressure door fittings, actuators, seals, shafts and other components. Material will be supplied against the following Standards as applicable:

  • AMS 5845 – solution heat treated, cold drawn and aged bars
  • NACE MR 01-75 – sulphide stress cracking resistant material for oil field equipment
  • AMS 7468 – bolts and screws, forged head, roll threaded after ageing
  • Mechanical Tests are conducted at room temperature in accordance with ASTM E8,; hardness in accordance with ASTM E18; Macrotech in accordance with ASTM A604, Grain Size in accordance with ASTM E112.
