Sandblasting Profiles: What abrasive should I use?

Anchor patterns are extremely difficult to approximate due to the many variables at play.  Use this information with Caution!  This is only an approximation.

The type of metal use in this example was hot rolled steel with tightly adhering mil scale.  The type and hardness of your substrate, how thick the scale is, the degree of cleaning you are attempting to achieve, experience and skill of the person performing the sandblasting, etc will all factor into your end result.  In this example, the pressure blasting was done using a 90-100 psi nozzle pressure.  The depth of the anchor profiles listed below are approximations only, and are on average.
