Limiting Chemical Composition, UNS N08926, ZAPP 25-6Mo
The chemical balance (and especially the 25% nickel and the 0.20% nitrogen contents) provides significantly better resistance to chloride-ion stress corrosion cracking than lower nickel alloys such as AISI 317 stainless steel. This is illustrated quite well by the Copson.
The ZAPP 25-6MO wire produces higher mechanical properties than ZAPP 316. Tensile strengths in the order of 210/250,000 psi are achieved through cold drawing. At these strength levels, the wire is ductile and able to successfully pass the wrap test in the as drawn condition as well as the as drawn plus exposed to temperatures as high as 400°F conditions. This wrap or bend test shows no surface cracking or failure U-Curve in the INCO publication IAI-46-3.
ZAPP 25-6MO is also identified as UNS N08926. Wire products are covered by ASTM B649. A number of other commercially available alloy designations are related to alloy ZAPP 25-6MO through the UNS N08926 designation or through published chemistry ranges. These alternate designations or trademarks include:
o INCO® alloy 25-6MO
(trademark of Special Metals Corporation)
o GD31MO (trademark of Central Wire Industries)
o SUPA 75 (trademark of Central Wire Industries)
o Cronifer® 1925hMo (trademark of Krupp VDM)
o AL6XN (trademark of Allegheny Ludlum
Corporation)
o Phy 4529
(trademark of Metalimphy Alloys Corporation)
Through the connecting UNS NO8926 alloy designation, ZAPP 25-6MO, SUPA 75, and GD31MO describe the same alloy and therefore have equivalent chemistries.

Examples of Theoretical Acceptable Well Environments for ZAPP 25-6MO Wire*
* The theoretical acceptable well environments are based on the SOCRATES software. SOCRATES is a comprehensive material selection tool for oil and gas applications that selects corrosion resistant alloys (CRA) through material evaluation based on mechanical strength parameters, heat treatment/cold work and ardness limitations. The program also evaluates the characterization of the environment in terms of operating pressure, temperature, pH, H2S, chlorides, elemental sulfur, aeration, gas to oil ratio and water to gas ratio water cut. Stress corrosion cracking, hydrogen embrittlement cracking, sulfide stress cracking and
resistance to pitting corrosion are also evaluated. The examples above are based on the environment listed and do not take into consideration the actual values of elemental sulfur, aeration, gas to oil ratio and water to gas ratio water cut.
