5 Facts About Manganese in Steel | Speaking of Precision …
16/2/2010· It’s effect on hardenability is greater than that of any of the other commonly used alloying elements. Manganese is also an active deoxidizer , and is less likely to segregate than other elements. Manganese improves machinability , by coining with sulfur to form an soft inclusion in the steel that promotes a steady built up edge and a place for the chip to break.

Abrasive blasting - Wikipedia
Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants..
How to apply coolant and cutting fluid in turning
It depends a lot on which workpiece material, which grade and what cutting data you machine in. For thin coated grades, like first choice PVD-grades for ISO S, it is best to use both over and under coolant to protect the insert from heat and avoid plastic deformation.

How to Choose the Right Blast Nozzle for Wet Abrasive …
Some manufacturers produce their own composite carbide nozzles which are even harder than boron carbide. Nozzles are not cheap to replace. One benefit of vapour abrasive blasting is that your nozzles will last up to 3x longer than a dry blasting nozzle because the particles are enclosed in a lubriing water jacket, which reduces friction between the abrasive and the nozzle lining.
