316 Austinetic Stainless steel hardening?
« on: January 22, 2008, 07:57:23 AM »
Hey guys/gals new to the site looks pretty cool!

So I have an (316) austinetic stainless steel pipe the diameter is that of a large sharpy marker that I need to harden any ideas on how this is possible? I was thinking induction or "EndurAloy" boronizing process to harden the pipe.

It is use is to carry a 35kg sled down an iced track. The idea is that the harder the steel the less heat transfer between the ice/steel which should result in faster speeds. The coefficient of friction is already very low and is reduced by various polishing methods.
I have attempted to Cryogenic treating of this steel and the results are varried the steel polishes easier and smoother but the hardness did not change and as a result the end speed of the sled did not change much.

I have attempted to find a coating that could work as well but to date nothing.

Any ideas?

Carbon composition for 316 SS (www.matweb.com is < 0.08%. So we can expect that this SS is quite soft because C composition affect the hardness. Basically, there are 2 best methods to increase hardness. First, you can do carburization http://en.wikipedia.org/wiki/Carburizing. Second you can do heat treatment process. Heating the steel to Austenitic region and rapid cooling (quench in water) to martensitic region. http://en.wikipedia.org/wiki/Heat_treatment
This for your reference http://iert.in/iron-and-its-phases/


Hope this help you a little  ;)
