The resulting dross that hardens on the bottom of the plate is very easy to remove and often does not require secondary operations like grinding.

This is especially true for thicker stainless steel plates where plasma cutting is almost universally considered the best solution. When mild steel is cut with o2 air the viscosity of the molten material is much lower than when cutting stainless steel. With an edge start plasma can cut up to about 160mm. Precision plasma can pierce and cut stainless steel up to around 40mm and high amperage plasma systems can pierce and cut stainless steel up to around 100mm.
