Why can't stainless steel tubes be cut with acetylene?
Is mainly from Huoxian, heating flame is mainly open before cutting and cutting plate preheating on the auxiliary heating.Stainless steel, chromium containing at least 13% or more, it hinders the exothermic oxidation and melting phenomenon, which is higher than that of iron chromium to 316 degrees, 1855 degrees, so can not use stainless steel oxygen - acetylene flame cutting.
That is because the iron element in the high temperature, if the above 99,6% will occur on the oxygen oxidation phenomenon is very strong, because of the heat transfer cycle, in order to make the cutting to continue uninterrupted, continuous heating it when cutting calories.
To know why stainless steel tubes cannot be cut by acetylene, we must first understand why carbon steel can be cut by oxygen acetylene flame
