Hardened steel is a type of metal that has been highly tempered to make it more rigid, durable and resistant to wear and tear. It is commonly used in the manufacturing of tools, machinery, and equipment that require high strength and durability. Cutting hardened steel can be a challenging task, especially for those who do not have the right equipment and experience. In this article, we will explore the different ways on how to cut hardened steel.
1. Using a hacksaw
One of the simplest and most affordable ways to cut hardened steel is by using a hacksaw. A hacksaw is a hand tool with a thin, sharp blade that is mounted on a frame. This tool is ideal for cutting small pieces of hardened steel, such as a bolt or a small rod.
To use a hacksaw, place the hardened steel on a secure surface and clamp it down to prevent it from moving. Then, use the hacksaw to cut through the metal by applying firm and steady pressure. It is important to use a high-quality hacksaw blade to ensure a clean and precise cut.
2. Using a reciprocating saw
A reciprocating saw is a powered tool that uses a reciprocating motion to cut through materials, including hardened steel. This tool is ideal for cutting larger pieces of hardened steel, such as a steel pipe or a thick metal plate.
To use a reciprocating saw, attach a blade that is designed for cutting hardened steel. Then, place the hardened steel on a secure surface and clamp it down to prevent it from moving. Start the reciprocating saw and use it to cut through the metal by applying steady pressure. It is important to wear safety goggles and gloves when using a reciprocating saw.
3. Using an angle grinder
An angle grinder is a powered tool that uses a rotating abrasive wheel to cut through materials, including hardened steel. This tool is ideal for cutting thick pieces of hardened steel, such as a steel bar or a metal tube.
To use an angle grinder, attach a cutting wheel that is designed for cutting hardened steel. Then, place the hardened steel on a secure surface and clamp it down to prevent it from moving. Start the angle grinder and use it to cut through the metal by applying steady pressure. It is important to wear safety goggles, gloves, and a face shield when using an angle grinder.
4. Using a plasma cutter
A plasma cutter is a high-powered tool that uses a plasma arc to cut through materials, including hardened steel. This tool is ideal for cutting complex shapes and designs in hardened steel, such as a metal sculpture or a custom metal part.
To use a plasma cutter, attach a plasma torch that is designed for cutting hardened steel. Then, place the hardened steel on a secure surface and clamp it down to prevent it from moving. Start the plasma cutter and use it to cut through the metal by following the design or shape that you want to cut. It is important to wear safety goggles, gloves, and a face shield when using a plasma cutter.
In conclusion, cutting hardened steel requires the right equipment and experience. Whether you are using a hacksaw, a reciprocating saw, an angle grinder or a plasma cutter, it is important to wear the appropriate safety gear and follow the manufacturer’s instructions carefully. By following these tips, you can cut hardened steel safely and efficiently.

Frequently Asked Questions about Cutting Hardened Steel
What is hardened steel?
Hardened steel is a type of steel that has been treated with heat to make it more durable and resistant to wear and tear. This process, known as hardening, involves heating the steel to a high temperature and then cooling it rapidly to create a harder, more dense material.
What tools can be used to cut hardened steel?
There are several tools that can be used to cut hardened steel, including angle grinders, rotary cutters, saws, and plasma cutters. The choice of tool will depend on the thickness of the steel, the shape of the cut, and the level of precision required.
What safety precautions should I take when cutting hardened steel?
Cutting hardened steel can be dangerous, so it is important to take the proper safety precautions. Wear eye protection, gloves, and a face mask to protect yourself from sparks and debris. Use the appropriate tool for the job and make sure it is in good condition. Work in a well-ventilated area and keep flammable materials away from the work area.
What are some tips for cutting hardened steel?
To cut hardened steel, it is important to use the right tool and technique. Start by marking the cut line with a marker or chalk. If using a saw or rotary cutter, make sure the blade is sharp and use a slow, steady motion. If using an angle grinder, use a cutting disc and move the grinder in a back and forth motion to create a groove before cutting through the steel. Always be patient and take your time to ensure a clean and precise cut.
