Conditions for stainless steel cutting
First: in the cutting process of stainless steel, the ignition point cannot be higher than the melting point.
Second: the melting point of the oxide of the stainless steel pipe must be lower than the melting point of the stainless steel pipe, and the fluidity is good, so that the liquid can flow easily, the oxide slag can be blown off, and the cutting process can continue.
Third: only when the stainless steel pipe releases enough heat during combustion can it preheat the stainless steel pipe at the lower layer. The more heat released, the greater the preheat effect, which is more conducive to the smooth progress of the gas cutting process.
Fourth: the thermal conductivity of stainless steel pipes must be low. When the thermal conductivity of the stainless steel pipe is high, the heat supplied by the preheating flame and the combustion of the stainless steel pipe will be quickly lost to the inside of the stainless steel pipe, so that the temperature at the notch will drop sharply.
Fifth: the impurities in the stainless steel pipe that hinder the gas cutting process and improve the hardenability of the steel should be less to ensure the normal gas cutting.
