Stainless Steel (INOX) Blast Media – Choice And Use

 

Abrasive Media
Stainless medias are of a hardness on MOH’s scale 7 – 8

It should be noted that any abrasive described as 6 and over on the MOH scale is classed as abrasive

Stainless Steel with Chrome / Nickel (Inox Cr / Ni)

This media can be used with air and turbine blasting on component parts requiring soft abrasion (new media is roundish and not so hard media).

  • This blast media has good resistance to rust and high durability
  • Particularly used on aluminium, brass, copper and alloys, stainless steel and stone slabs
  • Round particle shape allows soft abrasion effect; it has a high resistance to corrosion, avoidance of dust effects, low wearing of equipment, long life of media
  • Finer sizes will compare with a glass bead; provides a sateen finish and does not tend to figure mark as glass beaded surfaces might.

 

Stainless Steel with Chrome ( Inox Cr )

This media can be used with air and turbine blasting on component parts requiring more abrasion (new blast media is roundish in shape and rather harder media than that with Nickel).

  • This blast media has good resistance to rust and high durability
  • Particularly used on aluminium, brass, copper and alloys, stainless steel and stone slabs, but produces a slightly more abraded textured finish than that with Nickel described above
  • Round particle shape allows abraded effect; it has a high resistance to corrosion, avoidance of dust effects, low wearing of equipment, long life of media
  • Stainless chrome alloy blast media is more commercially priced
