wear resistant steel? 1

[t4h3r]

Dear all

would you please help me to choose a wear resistant steel, which is not expensive and able to machining with cnc milling or wire cutting machines .

thanks in advanced

Try AR400 or the ESAB Hardox grades.

metengr nailed it, the AR series has several different grades, 400 is great. SSAB Hardox also has several grades to choose from in addition, there is SSAB Boron, also with several grades. I've used the AR materials on several occasions and I've used the SSAB Boron, only once, and they are excellent materials and easy to work with.

The steels mentioned are very good for resistance to abrasive wear, such as handling rock and sand.
If other wear mechanisms are involved there may be better options.

If the wear is due to erosion caused by air borne particles in a coal pipe, EPRI ran some serious tests back in 1988 and had this to say.
"Irons and steels for erosive wear applications - Firstly it should be noted that mild steel has reasonable performance for erosive wear, Hardening of the steel, as in several proprietary branded materials makes little or no difference in this application and there are no recommended materials . In order to improve the erosion resistance it is necessary to incorporate hard carbides."

Wear resistant steels often are a manganese or boron alloy that improves abrasion resistance.

As usual, more information about the specific application would be helpful. What do you mean by "wear resistant"? What is your definition of "not expensive"? Depending on the size/shape/precision of your part, CNC milling can be an economical approach or an expensive approach for producing it. Wire EDM is only economical for a few limited applications. Great for difficult to machine metals, but it's a relatively slow process and somewhat limited in the geometry/profiles it can cut.
