Nitralloy 135

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

For more information on pricing, try some of the suppliers from this Google search:

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:

Thanks, I have already read those, ad done major searches all over the place, and requested some quotes, so far I still don't have an idea how expensive it is ... if it is cheap, then I don't need any alternatives, but if it is not ... then I do.

Hi

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
