Using blanks can be difficult or impossible depending on the geometry of your parent material. If you need a faster, more dynamic solution, hardfacing can enable you to quickly safeguard your tools against wear. The rough surface that grit hardfacing produces can also be beneficial depending on your application.

Grit Range: The sizing of the carbide, given in top and bottom screen sizing. The number equates to number of openings per inch, so a larger number is a smaller size particle falling through it. The number indicates the material on top of the screen.
Coverage: How tightly the grit will lay in the weld using a feed rate of 100 grams per minute. Open means the wire matrix between the carbide grit will be as big or bigger than the particles themselves. Medium equates to half to full size, and dense has the particles practically touching throughout the weld.
Best Media Use: In general, it is best to match the grit size with the media causing wear. Rocks tend to have either a constant contact point or large and variable gaps, whereas sand is a constant stream of fine points/gaps. Slurries tend to require fine carbides applied densely to minimize weld matrix erosion.
Typical Usage: Industries where the range is found on a common basis. It is by no means an exclusive list. There are mines which utilize very fine carbides due to the nature of the extracted material.
