Waterjet vs. Plasma Cutting

Stainless steel distributors like Alliant Metals can provide multiple services in addition to selling stainless steel sheets and plates. One of the most common services is metal cutting, but there is more than one method. In this article, we are comparing two methods: waterjet and plasma cutting. Both of these methods are effective for cutting stainless steel sheets and plates, but they each have their particular benefits in certain situations.

Join the Alliant Metals team as we compare waterjet and plasma cutting as methods for cutting stainless steel sheets and plates.

Waterjet Cutting

• Precision Cutting: Waterjet cutting offers high precision within .005 of an inch. This level of precision makes waterjet cutting the preferred method for projects with detailed specifications.
• Environmentally Friendly: Waterjet cuts produce no hazardous waste. The abrasive is garnet, a natural substance, so the process does not use or produce any contaminants.
• Material Integrity: Waterjet cutting does not use heat, so there is no risk of weakening the metal. Some alloys become weak when heated, so waterjet cutting preserves their structural integrity.
• Cut Thick Metal: Thick materials are no match for waterjet cutting. This method can cut through steel up to three inches thick.

Plasma Cutting

• Fast Cutting: Plasma cutting is faster than many other methods. The speed makes the process more efficient, which can reduce production costs.
• Cost Effective: In addition to being efficient, plasma cutting is also a lower-cost cutting method. For example, it is about half the cost of oxy-fuel laser cutting.
• Cut Multiple Thicknesses: Plasma cutting can be done on a number of metals with different thicknesses with the same level of precision and effectiveness.
• Ease of Operation: A plasma torch is a relatively simple tool, which contributes to this method’s lower cost. Other methods require more complex tools and adjustments, which are not necessary for plasma cutting.
