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!.

During aging, precipitates form at locations in the cold worked structure locking in dislocations further strengthening introduced from work hardening processes.

Depending on the prior cold work if any and the aging temp you can reach a tange of properties. We can not hold tolerances and now I am looking for another stainless product that has the hardness and strength of MP35N but more readily available. With less cold work reduction, the alloy has the best balance of strength and stress corrosion cracking resistance SCC for harsh environments.

You might try Technical Metals or any other supplier of aerospace materials for your plate. In reality almost everyone uses it in the cold worked and aged condition. I need to form the material on the ends to form a radius and need some assistance on the heat treat process that will afftect the ingrity of the material. The amount of cold work in MP35N defines the recommended aging treatments.

Thank you for the information and now it takes me to another question. Fastener system components — pins, tension bolts, shear bolts, engine bolts, tie rods and all critical high integrity corrosion resistant bolts. I suggest you work with Carpenter or H. Both of the Multiphase alloys require strain hardening, usually at the mill, to achieve their maximum strength level. In order to form this, we actually took bar stock and machined it to flat plate to wire edm a flat band that is.


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® Alloy

One thing I failed to mention was the material needs to be in a sheet or plate. There are some very high strength age hardening stainless steels as well, like Custom Age and from Cartech. Is this material already heat treated? This failure is killing me 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. There is no lubricant involved. Download Now White Paper: If you didn’t need that strength level there are easier ways to get there.

Are you an Engineering professional? All I know about MP is that it has higher alloying to allow strain hardening of larger product sizes, greater than several inches.

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. Download Now Defense manufacturing is all about project manufacturing and project accounting.

The Eng-Tips staff will check this out and take appropriate action. Neither of these grades possess the corrosion resistance of MP35N, so you will need to take this into consideration.

This was the original name. Cartech calls their maraging steel NiMark In your reply you state that the AMS is solution annealed and worked harden and is that the standard.

Qms this will require close communication with the material supplier and the entity ies performing the forming and heat treating.

If I am unable to change from MP35N, can 58844 let me know what the co-efficient of friction is at C? We have contacted Carpernter and have not received any response.

Will we need to anneal the material and then heat treat to get this? Promoting, selling, recruiting, coursework and thesis posting is forbidden. I think from the extream yielding the properties will be changed.
