Austinetic Stainless Steel (316)
(OP)
Hi I have a question: I have a (316) austinetic stainless steel pipe that I am looking to harden not sure how to go about this process.
I was thinking induction? Or: EndurAlloy a boronizing process. (http://www.endurancetechnologies.com)
The pipe is meant to go on the bottom of a sled that rides on ice aprox. 120-130km/hr. The idea is that the harder the steel the less heat transfer between the ice and steel which should translate into faster speeds.
I have tried cryogenic treating it has resulted in a nicer polish smoother finsh but thats about it.
I have thought about coating but the steel can not change color (grey) and I have yet to find a coating or method that would not negatively effect the steels coefficent of friction value. I have had some tests done and the pipe already posesses a low RA value so smoothnes is not an issue but hardness is.
Any help would be apreciated. The more info the better.

There is a patented process by Bodycote "Kolsterizing", you can contact them for details.

This process of Kolsterizing can it be done to a 316 steel?
What about coatings do you know of any that would make the steel pip harder but retain its smothness?

Did I miss something in physics class?

dempending on size and volume you could do this manually with something like a Dyna Brade or build some type of brushing system etc.
just a thought

By "pipe" I meant a general characteristic of the runner itself. I am sorry to be so vauge with the information regarding the characteristics of the "pipe" in question as well as its use but there are some parameters that need to be met such as protecting a lasered stamp that is on the steel as well as not altering its color.
I am not sure I follow you on "smooth doesn't help here" the smoother the surface the less friction will exist the faster the sled should travel.
I agree that you do need something hard that is the idea of this post to find some way to harden the 316 steel even if it is just a surface treatment.
As for "btrueblood" comment, there is 1 accepted truth in this process that I am involved in and that is this: the harder the runner the faster the sled travells even if it is skidding and hitting walls.
But to summarize yes the idea is to harden the steel in some fashion or apply a coating which so far has proven to be very dificult.
The Kolsterizing proces looks very promising.
Any other ideas would be awesome.

The problem that I see with 316 is that you might get surface hardness, but the bulk hardness will remain low.
You can always grind or polish the hardened surface. Having a great surface finish on the starting material doesn't assure you of anything.

I also agree a polished surface ensures nothing other than a smother running surface. It is hardness that is the goal.

Fair enough. But what does heat transfer have to do with it, or more specifically, how do you expect a hardness treatment of the blade to affect heat transfer.

I am curious about inserting diamond and or carbide tips into the steel. I am will look more into it and post on here to see if someone has a link for a company in North America that does this?

1)I tried the boronizing and needless to say it did not work the whole length turned dark grey almost black the groves were also distorted. So that was a no go! The stamps well those were a write off.
2)I have also tried a coating "Chromium Nitriding" this turned the steel a grey color not good but on the plus side the groves were unaltered.
3) Kolestering which was mentioned here sounds like an awesome idea, unfortunately the size of the steel is to long. Body Cote did offer an alternative in France called Novix, has anyone heard of this treatment?
This is where I need some assistance. I have been reading about "Ion Implants" from what I understand this can improve wear resisitance, increase surface hardness, improve glide properties all without altering the color or damaging the surface of the steel. Aperantly it even works on steel that has been polished to a high shine.
I have yet to find anywhere in North America well even the World that offers this service. Does anyone know of a company I could contact. Or even if I am posting this question in the right forum.
Thanks, in advance.
