AMS 5844 PDF

For AMS (fully strength/heavily cold worked) material, the alloy should be ages at ºF – ºF for 4 hours. For optimum sulphide SCC resistance. This specification covers a high-strength, corrosion-resistant alloy in the form of bars. MP35N is available for order in round bar, strip and wire. Call Michlin today for all MP35N needs. Alloy MP35N can be delivered ASAP. Call Today!.

It’s easy to join 58444 it’s free. MP35N Ni Co Cr Mo 35 35 20 10 is a nickel-cobalt base alloy that is often specified in subsea special fastener designs due to its unique combination of properties — ultra high strength, toughness, ductility and outstanding corrosion resistance.

Close this amz and log in. You might try Technical Metals or any other supplier of aerospace materials for your plate. Hello it is RosieGirl and i now understand what each of you stated regarding trying to machine MP35N. In your reply you state that the AMS is solution annealed and worked harden and is that the standard.

The part is edm’d and heat treated to form the radi on each end.

I don’t know where to look now as Timken has cast Latrobe Steel aside. They will have metallurgists that can help you with these challenges of obtaining high strength in the appropriate product form and suggest processing options on how to achieve the desired part shape.


Our people say that it works better than MP35N. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Rosie, The coefficient of friction for MP35N against what? I would recommend choosing an other type of material if possible. I think from the extream yielding the properties will be changed.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Download Now White Paper: The forming process would add incremental strain that hopefully would be sufficient such that the part could be finally aged to the desired strength levels. The Eng-Tips staff will check this out and take appropriate action. Click Here to join Eng-Tips and am with other members!

Exposure to temperatures much above the recommended aging temperatures may result in a significant and non-recoverable loss in strength caused by the reversion of the cold-worked metallurgical structure to the much softer annealed structure.

MP35N Strain Hardened Ground AMS – Metal and Metallurgy engineering – Eng-Tips

Hi All Here is some strange material. In addition, all critical manufactured special fasteners exhibit exceptional resistance to crevice corrosion cracking in seawater and other hostile environments hence being a popular choice for high integrity applications in offshore and subsea industries. Thank you for your information.

In addition I would recommend contacting Carpenter and request their advice. Will we need to anneal the material and then heat treat to get this? I may sound confused, cause I am and need your assistance.

We need to be able to take both ends and form a 2 inch radius while maintain the yield of ksi and tensile of ksi. During aging, precipitates form at locations in the cold worked structure locking in dislocations further strengthening introduced from work hardening processes. Cartech’s proprietary Aeromet and Aermet can also be heat treated to a similar strength range. Is the part being heated? Obviously this will require close communication with the material supplier and the entity ies performing the forming and heat treating.


Thank you for the information and now it takes me to another question. Neither of these grades possess the corrosion resistance of MP35N, so you will need to take this into consideration. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. There are some very high strength age hardening stainless steels as well, like Custom Age and from Cartech.

One thing I failed to mention was the material needs to be in a sheet or plate. Now I must ask for another question.

Alloy MP35N (AMS 5844)

Next, it will be very difficult to make this part using the manufacturing method that you have described. The amount of cold work in MP35N defines the recommended aging treatments. There is no lubricant involved. If I am unable to change from MP35N, can anyone let me know what ans co-efficient of friction is at C? Defense manufacturing is all about project manufacturing and project accounting.

If you aams need that strength level there are easier ways to get there. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Perhaps you could solution anneal the initial bar, then cold work the bar to the proper thickness and shape, and then age it to the right properties, but this sounds like it is outside your company’s capabilities. High strength special fasteners for marine components.
