Wear Strip material

Wear Strip material

I need a wear strip for a HRC 58-60 3/4" wide cam follower. The strip will be 1/4" thick by 1.5" x 30" LG. I was thinking of flame hardening to get it around HRC 60 but its thin so I think it will bend. Looking for other cost effective material ideas.

RE: Wear Strip material

You can buy these materials directly from specialty steel suppliers, in finished form, as bar stock. Ask some of them. It’s been so long since I’ve spec’ed. any that I don’t remember ASTM numbers, etc., but I have dealt with your problem a number of times before. You do not want to have to do any special treatment yourself. The big problems are that it is not weldable, it wears out tools quicker than you can change them becuase it is so hard, so minimize and really clean up your connection details to the supporting structure. Consider a bar which is not wider than needed and maybe a bit thicker than you think is needed, so there is limited curling of the bar in cross section due to the running of the cam roller.

RE: Wear Strip material

How much load will it carry? Consistent or varying? What duty cycle? Reciprocating? Speed? What environment?

I have seen hardened steel rails supporting a chain conveyor in a water spray replaced every year for 15 years until they were replaced one year with plastic rails. Six years later they were still there. Not saying it will work for you, but harder is not always better.

RE: Wear Strip material

And what is behind it supporting it?
Strength has nothing to do with how much is defects under load, all steels will deflect the same amount.
It is just that softer ones will take a set at lower loads.
