Need your springs to survive in a very corrosive environment? MP35N might be for you

MP35N (AMS5844) can be used in harsh environments and is very good at resisting corrosion where stainless steel such as AMS5678 might fail. Once the cold drawn material is aged at between 538˚C – 649˚C for between 4 -4 ½ hours the mechanical properties (as a minimum) are 1793MPa (260KSI). This is nearly as good as AMS5678 but with far superior corrosion resistance.

If you are struggling with AMS5678 failing due to stress corrosion cracking then this is always a very good material to try.

MP35N can be used between -200˚C and as high as 350˚C (depending on the application)

We do always recommend however that this material is shotpeened to AMS2430 (with a post peen glass bead decontamination) as this considerably improves fatigue performance.

I have been working with G&O since October 2019 and I could never say a bad word about this company. I have always been supported with important and critical items and as a company they are meeting my personal requirements. The business relationship with G&O is strong even during the hard times of the COVID-19 pandemic. G&O is self managing the VMI system each week I am up to date with any part number supplied by them. I would recommend anyone at anytime a collaboration with G&O. Tomasz Grabarek Material Controller - Incora
