Tool steel is a type of alloy steel used in manufacturing tools, dies, and machine parts. It typically contains tungsten, molybdenum, chromium, vanadium, and cobalt. One of the most widely used types of tool steel is H22 tool steel. H22 Tool Steel, also known as UNS T20822, is a well-known and widely used material in the tooling industry. This high-carbon, high-chromium steel is designed to withstand high temperatures and maintain excellent wear resistance, making it a popular choice for applications where strength and durability are key. The composition of H22 Tool Steel contains high levels of tungsten and molybdenum, which add to its impressive properties. With its excellent toughness, high resistance to thermal fatigue, and exceptional hardness, it’s no wonder that SAE-AISI H22 Tool Steel is a top pick for manufacturers and engineers alike. Whether you’re working with cutting tools, punches dies, or any other tooling application, H22 Tool Steel is a formidable material that won’t disappoint you. In this blog post, we will discuss the uses and benefits of H22 tool steel as well as its heat treatment and machining processes.

H22 Tool Steel Uses
Tool Steel H22 is known for its toughness and durability. It can be used in a wide range of applications, including injection molding dies, punches, and other cutting tools. It is also commonly used in automotive components due to its corrosion resistance in high-temperature environments. Tool Steel H22 has excellent wear resistance making it ideal for use in die-casting molds or extrusion dies. Its hardness makes it an ideal choice for fasteners such as nuts and bolts and any other application requiring high-strength materials that are resistant to wear over time.
H22 Tool Uses in Industries
In the automotive industry, H22 tools are used for various purposes. One of the main uses is in manufacturing, where H22 tools are used to cut and shape metal components for vehicles. They are also used in maintenance and repair work, such as removing bolts and screws from engines or other parts. H22 tools are known for their strength and durability, making them essential in this industry.
The aerospace industry also relies heavily on H22 tools. These high-strength tools are essential for constructing aircraft and spacecraft, as they can withstand extreme temperatures and pressures. H22 tools are also used to maintain and repair these vehicles, ensuring that they remain safe and functional during flights.
H22 tools play a crucial role in the construction industry as well. From building skyscrapers to residential homes, these powerful tools are used to drill holes, fasten materials together, and cut through tough materials like concrete and steel. Their versatility makes them valuable assets on any construction site.
Oil & Gas Industry
In the oil and gas industry, H22 tools are vital for drilling into the earth’s surface to extract natural resources such as oil and gas. These industries require heavy-duty equipment that can withstand harsh conditions, making H22 tools an ideal choice due to their strength and durability.
H22 tools have numerous applications within the manufacturing industry. From producing machinery to creating small electronic components, these versatile tools can handle various tasks with precision and efficiency. Their ability to withstand high torque levels makes them ideal for use in assembly lines.
Lastly, the shipbuilding industry relies on H22 tools for construction projects. Building ships requires heavy-duty equipment that can withstand exposure to saltwater and harsh weather conditions at sea. H22 tools provide this industry with the necessary strength and durability, making them a staple in shipyards worldwide.
H22 Tool Corrosion Resistance
Tool Steel H22 has an impressive ability to resist corrosion when exposed to certain chemicals or wet environments. This makes it an excellent choice for applications where corrosion could lead to damage or failure, such as boat propellers or medical instruments that may come into contact with bodily fluids. The chromium content in Tool Steel H22 gives it a protective oxide coating which helps protect against rusting and pitting from water exposure.
H22 Tool Heat Treatment & Machining
Tool Steel H22 can be heat treated using several methods, such as induction hardening or tempering, depending on the desired characteristics required in your application. In order to reach peak performance levels with your material, it must first be hardened by heating above 925°C (1700°F) followed by rapid quenching, which involves immersing the part into oil or water depending on the desired results needed from your part. After heat treating, you may need additional machining processes such as grinding or honing, depending on what type of surface finish you require on your material after heat treating is complete.
As you can see, Tool Steel H22 offers many advantages over traditional tool steels thanks to its superior corrosion resistance, heat resistance, ease of machining process, and hardness when hardened properly through a heat treatment process like induction hardening or tempering. Whether you’re creating injection molding dies, punches, or fasteners, this versatile tool steel will help get the job done right every time!
