Chrome Molybdenum vs S2 Steel – What’s the Difference

Chrome Molybdenum vs S2 Steel

When it comes to hand and power tools, it’s crucial to know that they’re made from high-quality materials to ensure that they’ll be durable and reliable throughout all your projects. Two of these tools most commonly used materials are chrome molybdenum and S2 steel. However, which one is better? This blog post discusses everything you need about chrome molybdenum vs S2 steel.

What is Chrome Molybdenum Steel?

Chrome molybdenum steel, also known as chromoly steel or chrome moly steel, is an alloy steel that contains chromium and molybdenum. Adding these two elements gives chrome molybdenum steel greater strength and resistance to wear than other types of steel. It is often used in the construction of race cars and aircraft parts.

What is S2 Steel?

S2 steel is a high-carbon tool that contains between 1% and 2% carbon. This makes it much harder than other types of steel but also more brittle. It is often used for cutting tools such as drill bits and saw blades.

Difference Between Chrome Molybdenum and S2 Steel

Properties of Chrome Molybdenum Steel

Chrome molybdenum steel has a high strength-to-weight ratio, making it ideal for use in applications where weight is a concern, such as race cars and aircraft parts. It is also resistant to wear and corrosion, making it ideal for use in high-stress environments. Additionally, chrome-molybdenum steel can be heat treated to increase its strength and durability.

Properties of S2 Steel

S2 steel is very hard, making it ideal for cutting tools. It is also resistant to wear and corrosion. However, because it is so hard, it is also brittle and can break easily if not used properly. Additionally, S2 steel can be difficult to work with because it tends to chip easily.

Which is Better?

There is no definitive answer as to which type of steel is better. It depends on the specific application for which the steel will be used. For example, if weight is a concern, then chrome molybdenum steel would be better than S2 steel. However, if the goal is to create a cutting tool that will withstand a lot of wear and tear, S2 steel would be the better choice.


In conclusion, both chrome molybdenum and S2 steel are excellent choices for different types of tools. If you need a hand tool that is tough, resilient, and corrosion-resistant, chromoly is the material of choice. On the other hand, if you need a power tool accessory with exceptional hardness and wear resistance, S2 steel is the way to go. Regardless of your choice, invest in high-quality tools from these materials to ensure they’ll last through all your projects.
