Nitralloy 135
Nitralloy 135
(OP)
Hi
How expensive is Nitralloy 135 and is there an alternative that can be used instrad, The application will be a dry rotary unit that has ceramic or carbon ceramic seals. I need something that will rather wear the seals and not the metal
Regards
Jonathan

Timken Latrobe and Atlas Specialty Steel (part of Slater Steel) are two primary producers of this alloy. You can obtain more information on this alloy from their websites:

Depending on the exact requirements, there may be a number of suitable alternatives. Nitralloy 135 is used because it responds well to the nitriding process. Nitriding imparts a hard, wear-resistant surface to suitable alloy steels. Carburizing, ferritic nitrocarburizing, and carbonitriding are other methods used to impart a hard, wear-resistant surface to steel components. The following technical paper may be of some use to you in comparing other materials and processes to Nitralloy 135:

Thank You, however I did come right with EN19 which can also be nitrided, In South Africa I found the closest to Nitralloy 135 was V820, it is almost the same, but for me to buy here is much cheaper than to import.
If you dont mind may I ask if nitriding changes any sizes on the material, like for instance heat treating sometimes makes it pull.
Thank you again for your post
