  • Keep the steel surface free of debris and contaminants

Cutting stainless steel with a torch is possible with the right type of torch. By understanding the pros, cons, and best practices of using plasma cutters, oxy-fuel torches, and water jet cutters, you can choose the torch that’s best suited for your needs.

Determining The Thickness Of Stainless Steel For Cutting

Can You Cut Stainless Steel With A Torch?

Stainless steel is a popular metal for several applications because of its corrosion resistance and high durability. However, cutting stainless steel can be a challenging process, especially if you don’t have the right tools and techniques. We will discuss how to determine the thickness of stainless steel for cutting and what are the best practices to adopt.

Understanding Gauge Measurements

Gauge is the unit of measurement used to describe the thickness of a sheet of metal, including stainless steel. The gauge value increases as the thickness of the sheet decreases. But, the relationship is not linear. For example, a gauge value of 18 corresponds to a thickness of 0.

05 inches, whereas a gauge value of 16 corresponds to a thickness of 0. 063 inches.

Measuring The Thickness Of The Stainless Steel

To determine the thickness of stainless steel sheets, you can use a variety of tools, including calipers, laser gauges, micrometers, and ultrasonic thickness gauges. Each tool has its pros and cons, so you should choose the one that suits your application.

Best Practices When Determining The Thickness Of The Steel

When you are determining the thickness of the stainless steel for cutting, you should keep the following best practices in mind:

  • Clean the metal surface before measuring – dirt and debris can affect the accuracy of the measurement.
  • Take several measurements – the thickness of metal can vary across the surface, so it’s best to take multiple measurements.
  • Choose the right tool – as we mentioned earlier, each tool has its limitations and strengths, so choose the one that’s right for the application.
  • Use the correct formula – once you have taken the measurements, you need to use the appropriate formula to convert the gauge value to thickness (in inches or millimeters).
  • Consider the cutting method – the thickness of the stainless steel will influence the cutting method you need to use. For example, thicker metal may require oxy-fuel or plasma cutting, while thinner metal can be cut using a sheet metal shear or laser cutter.

Determining the thickness of stainless steel for cutting is critical to ensuring that your cutting process is efficient, consistent, and safe. It’s essential to choose the right method to measure the thickness and adopt the best practices to achieve accurate results.

Use this guide to make the right decisions and cut stainless steel like a pro.
