The most fundamental material utilized in industries is metal, like construction, aerospace, automotive, and manufacturing. It requires strength and endurance, which are crucial for high resilience, particularly in severe environments. Metal’s significance is unquestionable, from beams of steel in tall buildings to titanium in planes.
However, could something as flowing as water cut through extremely sturdy material? Yes, given the correct technology and circumstances, water can cut through materials as hard as steel when pressurized to a severe level. Here, we will understand how these cutting-edge procedures function and what makes them so effective.
Can Water Cut Through Metal?
Yes, water can indeed be cut through metal using advanced water pressure cutters and high-pressure water cutters. These powerful tools utilize extreme pressure, sometimes exceeding 60,000 PSI, to generate a water stream that can cut through various materials, including hard metals.
At this high-pressure level, the water becomes a formidable force capable of easily displacing and eroding metal surfaces.
The high-pressure water jet can handle softer metals, but an abrasive material such as garnet is often added for cutting through tougher materials like steel.
This combination of high-pressure water and abrasive particles allows water-pressure cutters to penetrate even dense and resilient metals, delivering accurate cuts that are difficult to achieve with other methods.
The cold-cutting nature of high-pressure water cutters also means no heat damage, making it an ideal choice for applications where maintaining the metal’s structural integrity is essential.
Understanding the Power of Waterjet Cutting
The science behind water jet cutting is both powerful and fascinating. Using abrasive waterjet cutting PSI levels of up to 90,000, this technology can create precise, intricate cuts in hard materials like metal.
The water is forced through a narrow nozzle, producing a fine, high-speed jet that reaches supersonic velocities.
When garnet or other abrasive particles are added, the process gains additional cutting strength, especially for harder materials such as steel.
Abrasive waterjet cutting offers an efficient, non-thermal way to cut steel and other metals without risking deformation from heat. This method has revolutionized metal fabrication and engineering because it provides precision and cleanliness that few other cutting technologies can match.
If you’re considering cutting steel accurately and without heat distortion, abrasive waterjet cutting is among the best solutions, ensuring clean, accurate cuts for complex shapes.
What is the Purpose of High-Pressure Water in Metal Cutting?
The role of high-pressure water in metal cutting is essential to achieving clean, accurate cuts. The intense pressure generated by a high-pressure water cutter pushes water through a tiny nozzle, creating a narrow but extremely powerful jet.
For softer materials, pure water can be enough to cut through, but abrasive materials are typically added to increase the cutting power for metals. This combination allows high-pressure water cutters to achieve levels of precision that are difficult to reach through traditional metal cutting methods.
For anyone wondering, “How do I cut steel?” or “How to cut through metal?,” water jet cutting provides a safe and effective answer. The key advantage of this method lies in its cold-cutting nature; no heat is introduced during the process, which keeps the metal from experiencing any structural changes or weaknesses due to temperature shifts.
High-pressure water, especially when paired with abrasives, makes it possible to slice through metals quickly and efficiently, regardless of their hardness.
Pure Waterjet Cutting and Abrasive Waterjet Cutting:
There are two major types of waterjet cutting processes: pure cutting and abrasive cutting.
Pure Waterjet Cutting
This pure waterjet cutting technology employs only pressurized water. It is suitable for delicate materials such as foam, plastic, rubber, and also some types of wood. The high-rate speed operates as a micro-erosive force, which cuts through materials without producing heat or deformation.
Abrasive Waterjet Cutting
This abrasive waterjet cutting methodology utilizes, typically, garnet, which is mixed with the water stream. And that grinds away the surface of the materials when the water accelerates it at high rates of speed. This type of technique is more suitable for harder materials such as steel, titanium, or granite.
PSI for Waterjet Cutting: How Pressure Affects the Cutting Process?
One of the most important factors in water jet cutting steel is the pressure measured in PSI (pounds per square inch). High PSI levels are essential for cutting harder materials and achieving smooth edges.
In most industrial applications, PSI levels for water jet cutting range between 40,000 and 90,000, with higher PSI required for tougher and thicker metals.
How do you cut through metal with high PSI? The higher the PSI, the finer and more precise the cut can be, even on challenging materials. With sufficient pressure, the water jet gains enough force to create a thin, precise stream that quickly penetrates metal surfaces.
This high-pressure stream, especially when used with abrasives, erodes metals without heat, preserving the metal’s inherent properties and structural stability. Thus, PSI is crucial in determining how effectively and precisely water jet cutting can cut through different types of metals.
Abrasive Waterjet Cutting: Cutting Metals with Precision
Abrasive water jet cutting is an industry-standard technique for metals, combining the power of a high-pressure water jet with abrasive materials to enhance cutting strength. In this process, a high-speed stream of water mixed with fine particles like garnet is directed at the metal, allowing it to slice through tough materials like steel.
Abrasive particles improve the effectiveness of water cutting metal by adding a sharp, grinding action that speeds up the erosion of the metal’s surface, delivering precision in intricate and complex cuts.
When cutting with an abrasive jet on metal, this method provides exceptional results, creating a smooth, burr-free edge with minimal finishing needed. It’s a technique favored for projects requiring tight tolerances and precision, such as aerospace components and intricate industrial parts.
Abrasive water jet cutting is versatile and capable of handling various thicknesses and grades of metals, ensuring clean cuts even in high-strength materials.
Can water cut through hardened steel and other tough metals?
One of the remarkable capabilities of hydro-cutting metal is its ability to cut through hardened steel and other resilient metals. Metal cutting with water jet technology allows the water to reach incredibly high speeds when mixed with abrasive particles, which erode the metal surface, effectively cutting through tough metals like hardened steel, titanium, and stainless steel.
With abrasive particles and a high-pressure hydro-cutting system, metals that are typically challenging to cut can be processed smoothly without the risk of heat deformation or warping. This makes hydro-cutting metal ideal for automotive, aerospace, and heavy equipment manufacturing industries, where precision and structural integrity are essential.
At SS Engineering Works, we utilize water jet technology to cut through hardened metals, ensuring accuracy and maintaining the metal’s original properties.
How Thick Can Waterjets Cut?
One of the most obvious benefits of waterjet cutting is how well it can cut through a range of thicknesses. The greatest amount of thickness a waterjet can handle differs determined by the materials being cut, even though it can cut via:
- Mild steel up to 12 inches
- Aluminum: up to 10”
- Titanium: up to 6”
With the appropriate setting and abrasive, waterjet machines are capable of handling thicker materials, which makes them suitable for both heavy industrial use and delicate, complicated applications.
What are the Benefits of Cutting Steel with a Waterjet Cutter?

Limitations of Waterjet Cutting
Waterjet cutting provides several benefits over traditional cutting technologies when it comes to steel, including
1. Cutting Speed
Although waterjet cutting is very effective for numerous materials, it is often slower than laser or plasma cutting, especially when dealing with thicker metals. Laser and plasma cutters can cut through materials faster due to their thermal cutting method, which melts or burns through the material. On the other hand, waterjet cutting diminishes the material gradually, which is less time-efficient for thick or dense substances. As a result, waterjet technology may be less useful for applications that need high-volume, quick cutting.
2. Material Thickness
Waterjet cutting eliminates heat-affected zones, unlike laser or plasma cutting. This absence of heat stress maintains the material’s integrity, avoiding deformation and microcracks on steel surfaces. The lack of heat preserves steel strength, guaranteeing no heat-affected zones.
3. Cost
As opposed to other cutting technologies like laser or plasma cutters, waterjet cutting equipment often has a greater initial cost. Additionally, running the high-pressure pumps during waterjet cutting uses a lot of energy. The expense is further impacted by the abrasive ingredients, which require regular replenishment and include garnet. These expenses can easily mount up for smaller companies or operations, making waterjet cutting less practical, especially for work with low volume. The higher cost of high-pressure equipment maintenance adds to the overall operational expenses.
Conclusion
