Which of the following powders should be fed for effective oxy-fuel cutting of stainless steel?

Correct Option: A. Powder of steel is used with oxygen such a flame. This powder burns producing large amount of heat facilitating cutting.

What is the reason you Cannot cut stainless steel with an oxy-fuel torch?

Cutting Torches + Steel = Oxyfuel thick. But only metals whose oxides have a lower melting point than the base metal itself can be cut with this process. Metals such as aluminum and stainless steel cannot be cut with Oxyfuel due to the formation of an oxide that prevents oxidation from fully occurring.

What metal is the oxy-fuel gas cutting process used for cutting?

steel
Oxy-fuel cutting is a chemical reaction between pure oxygen and steel to form iron oxide. It can be described as rapid, controlled rusting. Preheat flames are used to raise the surface or edge of the steel to approximately 1800°F (bright red color).

How do you use oxy-fuel cutting?

In oxy-fuel cutting, a torch is used to heat metal to its kindling temperature. A stream of oxygen is then trained on the metal, burning it into a metal oxide that flows out of the kerf as dross.

What is the max pressure for acetylene?

15 psig
Maximum pressure. Under no condition shall acetylene be generated, piped (except in approved cylinder manifolds) or utilized at a pressure in excess of 15 psig (103 kPa gauge pressure) or 30 psia (206 kPa absolute).

Can we use LPG for gas cutting?

LPG is also used in cutting of most carbon steel because it cuts through across layers and jumps air gaps with ease, leaving no slag on the steel. It can tolerate a greater nozzle to workpiece distance which reduces the risk of molten metal splashing back onto the nozzle and causing a “backfire”.

How does oxy acetylene cut steel?

Basically, a mixture of oxygen and the fuel gas is used to preheat the metal to its ‘ignition’ temperature which, for steel, is 700°C – 900°C (bright red heat) but well below its melting point. The oxygen jet blows away the slag enabling the jet to pierce through the material and continue to cut through the material.

Which of the following material is best cut by oxy cutting process?

Explanation: The material which can be best cut with oxygen cutting process is Mild steel.

Can you cut stainless with Oxy?

An oxy-acetylene torch is fairly useless against a good grade of stainless steel. You can melt it away, but oxidation is the key to ”burning” regular steel with an acetylene cutting torch, and stainless is stainless because of alloying metals that make it very oxidation resistant.
