Rating abrasion resistant plate...

Rating abrasion resistant plate...

Rating abrasion resistant plate...

(OP)
Can anyone rate the different grades of abrasion resistant plate?  Mainly I want to compare the service life of ar400 and ar500 plate.  How much more life can I expect out of ar500 plate than the ar400?  I priced them both and the ar500 was about 11% more.  Can anyone comment on the use of Hardox?  How does Hardox compare in price, wear resistance and availability?

My application is a shaker feeder.  We want to line the feeder with 1/2" ar plate.  The material that we are conveying is scrap metal.  This scap metal can be most anything, aluminum, steel, copper etc...  The size is anywhere from 5 lbs to very fine, all with jagged edges.  There is constant rubbing and light to moderate impact.

RE: Rating abrasion resistant plate...

The web sites below provide a decent description and evaluation of abrasion resistant plates. In particular, they both rate relative wear of their products in certain environments.

From experience, we have successfully used the abrasion resistant plate from HARDOX in our fleet of coal barges. This environment is severe because of the combined effects of coal abrasion and impact during loading and unloading of barges. Also, the bumpers of the barges were fitted with HARDOX wear plate. This is an application where contact and occasional ramming occurs with concrete and steel piers, which results in severe impact loading to the bumpers.

I would contact these folks directly to discuss additional information regarding wear testing and specific applications.

RE: Rating abrasion resistant plate...

Abrasion tests are done with standardized equipment and conditions. It is doubtful if standard tests can duplicate real world conditions of specific shaker feeders.

Standard testing equipment suppliers like

or academic laboratories

may be able to suggest which standard test might approach
actual wear results.

Probably the manufacturers of abrasion resistant plates, given the intended use, might be able to suggest the more suitable of their materials.
