How to Form and Cut Inconel 625 Plate to Suit Custom Industrial Applications
Inconel 625 plate is extremely durable and resistant to high temperatures and corrosive environments, making it an ideal material for many industrial applications. The unique properties of this metal make it popular in industries as diverse as aerospace, chemical processing, and power generation. However, machining Inconel 625 plate requires specific skills and techniques, as it is extremely difficult and challenging to cut and form. In this blog post, we will explore how to cut and form Inconel 625 plate to fit custom industrial applications.
What are Inconel 625 plates used for?
Inconel 625 alloy plates are often made into pipes, plates, flanges and bars due to their excellent weldability and high formability. They are ideal for applications such as offshore piping systems, heat exchangers, chemical transfer lines and gas turbine piping systems.

Cutting Inconel 625 Plate Metal
Cutting Inconel 625 sheet metal requires specific skills and techniques as it is one of the most difficult metals to cut. This metal has high strength, hardness, and heat resistance, which enhances its resistance to deformation and cutting. Some of the most commonly used cutting techniques include:
Abrasive water jet cutting is the most commonly used technique for cutting Inconel 625 sheet metal. It uses a high-speed stream of water mixed with an abrasive such as garnet to cut the metal.
Plasma cutting is another preferred technique for cutting Inconel 625. The process utilizes an electric arc to melt the metal and blows in air to create a clean cut.
Laser cutting is also used to cut Inconel 625 sheet metal. The process is precise and produces high-quality cuts, but is relatively expensive and requires experience to operate.
Forming Inconel 625 Plate Metal
Inconel 625 sheet is ductile and can be formed into a variety of custom shapes and sizes. Forming Inconel 625 sheet requires specific techniques, such as:
Cold forming is bending Inconel sheet into the desired shape without heating. Cold forming requires high pressure and strain to achieve the desired shape, but ensures that the metal retains its properties.
Hot forming is heating Inconel 625 sheet to a specific temperature before forming. Hot forming reduces the strength of the metal, but can be used to form complex shapes that cannot be achieved with cold forming.
Cutting Tips for Inconel 625 Plate Metal
Cutting Inconel 625 alloy can be challenging, and using the wrong cutting technique can damage the metal or result in a poor cut. Here are some tips when cutting Inconel 625 plate:
Use the Right Cutting Tool
Inconel 625 requires a special type of cutting tool designed for high-performance metal cutting.
Set the Correct Cutting Speed
Cutting speeds should be low to prevent the tool from overheating and damaging the metal.
Use Lubrication
Lubrication prevents cutting tools from overheating and improves cut quality.
