That nullifies the properties or AR steel. We hope these videos continue to be a great help to you all! For cutting steel, they are quite useful, but it’s hard to get a good square cut. Laser cutting limits the amount of heating, thereby not annealing as much of the target compared to other cutting methods such as plasma cutting. This is commonly referred to as Heat Affected Zone (HAZ). Protector Series ... one of the common ways for people to get into a gun safe is by cutting through it with either a grinder or a cutting torch. Should a wheel break apart in use, pieces of the wheel could strike and injure you or a co-worker. What you must keep in mind is that AR500 was initially designed as an abrasive steel in the manufacture of earth excavating equipment. Our Steel Targets.
