5160

Walt2 · Jun 11, 2003

I have a piece of 5160 that I got from TKS. It cuts rather easy (I think) with a hacksaw, but it will dull even the good blades pretty quickly. Is this steel usually rough on saw blades?

It is used as a spring steel. I wouldn't think it be hardened past the mid 40's, if yours is hardened for that purpose. However, I think anything past 28 RC is not looked at as machinable. I could be way off base too. Never used the stuff, yet.

I use 5160 a lot and profile my blades with a hack saw....most of the steel I use is hot rolled. It can be a tough one on saw blades if it is the least bit hard. And 5160 tends to want to get hard very easily, especially under a dull drill bit.

The least amount of heat while drilling seems to harden the spot you are drilling and make it tough to keep the bit cutting. I have noticed that a hack saw blade seems to go dull much quicker cutting 5160 than it does with 1050 or 1084.

But these things are highly subjective and variable.

Use cutting fluids, both sawing and drilling.

You could always profile it with "hammer, heat, and anvil"...

Hey Walt, I second the cutting fluids and go slow. It is tough stuff even annealed, I think it has to do with the chromium content. But like Mr. Wilkins said it works real well with a hammer, forge, and anvil.

I use a Burr King and a 36G belt.

Is there any reason not to anneal it, just in case?

Walt2 · Jun 13, 2003

It was my understanding that it was annealed and as easy as it cuts, it probably is. It just surprised me how quickly it dulled saw blades. I wasn't using any cutting fluids, which would have helped I am sure. I am through with the sawing. Now, when I get time, I am going to try my hand at making a couple of blades.
