So you still couldn't be bothered to search "Meehanite". I guess ignorance is bliss.

The misinformation on these forums is alarming, Perhaps there should be some moderation in this regard. I am not a fan of censorship but a lie is a lie and deserves no leniency
That qualifies as a personal attack, which is in fact grounds for being thrown off...

Just for you I looked it up and found that ductile iron is one formulation of meehanite. Surprising how many different types of meehanite there is , some hard and some soft, some acid resistant. Yet there is even a grade for high strength and wear. While it is a process, its actually many processes for what you are looking to use the material for. To use the name meehanite you have to be authorized to use it. Its a trade mark. Free PDF books here.

I have seen name tags on the back of machines and including CNC machines which say meehanite. Yet when you drill different machines you will find different hardness of the cast iron. I have drilled and bored for ball locks to be mounted in the table on brand new CNC mills. It gives you an odd feeling to be drilling the table on a brand new machine that hasn't made a part yet.

Throwing the BS flag here. The Meehanite process was patented in 1931. Meehanite is not a material, it is a process. Specifically for cast irons of various properties. Ductile iron was invented in 1943 and the patent granted in 1949.
If you can't even spell Meehanite you should just STFU.

Even IF Meehanite is a process and not a material, it is apparently a Process for Making Better Material.

So What's The Problem ?

If Meehanite Processed Material is Superior then Go For It.

No Harm No Foul No Need to get your panties in a bunch and act all Meehanite (Superior ) to everyone.

Perhaps we should all be saying "Cold Process Rolled Steel" and "Hot Process Rolled Steel" instead of "Cold Rolled Steel" & "Hot Rolled Steel".
