Stainless Steel Friction

Stainless Steel Friction

(OP)
Hello,

I am looking for the friction factor between stainless steel to carbon steel. Any thoughts are greatly appreciated.

Thank you.
AKU.

I imagine stainless versus carbon steel may be a bit different, but the above is what I would start with

Thanks RobinHandy. but if you know any info about carbon steel to stainless... we are designing a guide support so wanted to use stainless steel as to reduce friction.

RE: Stainless Steel Friction

UAK, If you are trying to reduce friction why would you not use a PTFE or other slide plate material suitable for the application?

RE: Stainless Steel Friction

Sanity check!
I wouldn't count on steel/steel of any kind reducing friction to any significant amount to be important to your final result. If that is the difference of pass/fail, you're in deep trouble.

I want to use stainless steel material as guide bars and base plate. There going to be a slide bearing underneath the base plate.

RE: Stainless Steel Friction

Here we go again on the subject of friction between steel surfaces. I agree with BigInch on this point. Friction factors vary vastly dependant upon the condition of the surfaces. In an industrial situation steel to steel can be as high as the 0.8 value given by RobinHandy. What amazes me is the insistance on certain Companies to adopt the value of 0.3 for steel to steel friction factors for situations where , for example, the pipework is located on an offshore platform. It might be 0.3 for the initial installation but after a few years the friction factor would be well above 0.3. When you bring this up and say the assessment is incorrect using 0.3 the response is generally "That's what we always use" .
