Steel Grit is made by crushing and screening the resulting abrasive media and then tempering them to the desired hardness. Steel Grit has sharp edges and with the help that it can clean and smooth the blasting surface.

Steel Grit is fabricated by examination of abrasive media then tempering them to the specified hardness. Mainly, Steel Grit is employed to get rid of rust where the cleaning speed is high and rough finish is suitable. It also understands the term crushed steel shot. Most commonly steel grit is employed for the removal of mill scale and to get rid of different degrees of coating from the surface. G25 - G80 is employed most often and by repeated striking metal strength is increased. It can use concrete surfaces, rubber build-up removal, and adhesive removal. To select a blast media it's necessary to pick abrasive media very wisely in order that the specified result is often achieved and it's very essential for any blasting business.
90% of random hardness checks performed on a sample distribution shall fall within the subsequent ranges. S hardness range of 402-558 Knoop hardness number (40-51 HRC), M hardness range of 495-650 Knoop (47-56 HRC), L hardness range 612-754 Knoop (54-61 HRC), and H hardness of 732 Knoop minimum (60 HRC). The hardness could also be determined by any of the varied methods applicable to small sections like Micro Hardness Tester with a Knoop indenter, at loads determined to supply a reliable conversion to Rockwell C.

Ans.
Steel shots are typically harder and more durable than other types of blast media, such as glass beads or plastic media. This makes them more effective at removing tough surface contaminants, such as rust and mill scale. Steel shots can also be reused many times before needing to be replaced, making them a cost-effective option.
Ans.
Steel shots are small, spherical particles of steel that are used for shot blasting and peening applications. They are typically made by melting scrap steel and forming it into a spherical shape through a process called atomization.
Ans.
The two most prevalent forms of metallic abrasives are steel shot and steel grit. Because of its spherical form, steel shot will give the substrate's surface a smooth texture. The substrate surface will be etched and worn down by the randomly angular steel grit.
