In conventional Oxy-cutting the metal is first heated by the flame, then an excess of oxygen is supplied. This causes exothermic (heat generation) reactions which generate the
heat necessary to melt the oxides formed, which are then removed from the cut by the velocity of the gas jet.
Stainless Steel having a high level of Chromium (Cr) cannot be cut by simple oxy-cutting methods due to the refractory nature (very high melting point) of the Chrome Oxide which is formed.
Modified or other methods therefore have to be employed.
