In fact, nickel is so important that nickel-containing grades make up 75% of stainless steel production. The best-known of these are Type 304, which has 8% nickel and Type 316, which has 11%. Nickel provides these properties by changing the crystal structure of steel to an austenitic (face-centred cubic crystal) structure at almost all temperatures.
Granulated nickel slag is essentially an angular, black, glassy slag "sand" with most particles in the size range of − 2 mm (No. 10 sieve) to + 0.150 mm (No. 100 sieve). It is more porous, with lower specific gravity and higher absorption, than air-cooled nicked slag. Nickel slag is very abrasive and does not lend itself well to grinding.
used exclusively in stainless steel production. Due to the mechanical losses of ferronickel in the electric furnace slag, the nickel content ranges between 0.10 and 0.20 % while the amount of slag is about 2 Μt/y. For this reason, the slag is crushed and submitted to low-intensity magnetic separation to recover

The Difference Between Superfine Steel Slag Powder . Steel Slag Superfine Powder Steel slag is a side effect produced in the steelmaking process If it is not treated, it will cause harm to the environment and require manpower and material management The finished product after being ground by the ultrafine steel slag vertical mill is widely used in building materials and cement Roads
We have several hundred .625 in x 3 in 304 stainless steel tubes that were laser cut to add various tabs and slots. During the process a relatively large amount of slag was deposited onto the ID of the tubing. In order for the parts to be functional, the ID needs to have a decent surface finish, or at the very least not be rough from slag.
