what is the temperature of steel cutting torch?
- 1 decade agoFavorite Answer
Steel, a composition of iron and carbon, melts at around 1,370 °C. The torch commonly used by welders is called an oxy-fuel welder or cutter. The fuels used in this type of cutter is Acetylene (most common), Hydrogen, propylene, LPG, natural gases etc..
Acetylene, the most common fuel, can reach a temperatures between 3200 °C to 3500 °C (5800 °F to 6300 °F). However, the major drawback of this fuel is its use underwater, because, if the depth exceeds 33 feet/10 meters underwater, Acetylene becomes unstable, hence Hydrogen becomes its substitute.
Hydrogen on the other hand cannot exceed more than 2,000 °C, but when pre-mixed in a 2:1 ratio with pure oxygen, can reach temperatures up to 2,800 °C.

A cutting torch does not cut steel with a flame. The flame just preheats the steel hot enough so that the steel, itself, burns in the presence of all the excess oxygen in the flame. It is the heat released by the burning steel that produces the rapid temperature rise and the nice clean curf. Stainless steel not only does not rust because of the protective hard layer of oxide that it forms, it also has trouble burning for the same reason. You can slowly heat it with a flame until it melts, but you get a big, sloppy, wide melt zone, because the heat is being transfered to the metal from the passing flame, instead of being generated by the burning surface of the metal itself. A steel that makes lots of bright sparks when ground, because the specs catch fire as they are scraped off will also probably cut well. That metal catches fire easily. When you grind stainless you don't get bright or branching sparks, just little bits of hot metal, each protected by its own oxide from catching fire. -- Regards, John Popelish

Depends on the material and room around the beam. If you have the room and the space can survive the heat use mapp gas which burns at 5301 degrees F. Or better yet use acetylene which burns at 5720 degrees F. If there is not much room or the surrounding materials are too combustible use the diamond blade. Or rent a concrete cutter with a metal blade if you have the room but you need to keep the heat down.

Aprox. 1200 degrees
