How to Cut Stainless Steel With an Acetylene Torch

Stainless steel requires more heat than some other metals, but successful cutting is highly achievable.

1. Use a tape measure to measure the piece of stainless steel to be cut.

2. Mark the cutting line with a soapstone pencil, which remains visible even under intense heat.

3. Place the stainless steel onto a metal workbench free of flammables. Clean the workbench with a degreasing detergent prior to each use.

4. Clamp the stainless steel to the workbench, leaving the cutting area hanging off the edge of the table a minimum of four to six inches.

5. Place the cutting attachment on the torch handle and screw into place.

6. Wear a heat-resistant face shield, welding gloves and a welding apron.

7. Turn the acetylene torch on and begin heating the stainless steel along the cutting line until the stainless glows red.

8. Depress the cutting lever to increase the oxygen flow to the cutting tip, which concentrates more heat on the cutting line. Cut through the stainless steel.

Tip

Secure C clamps onto the overhanging stainless and onto a straight piece of angle iron, which will serve as a straight edge to help you follow a straight cutting line.

Warning

Allow the stainless steel to cool completely before removing it from the workbench. Remove all flammable items from the room, including paints and chemicals. Keep a fire extinguisher nearby in case of emergency.
