1070 Steel vs 1074 – What’s the Difference

1070 Steel vs 1074

Steel is an iron alloy widely used in various industries due to its high strength and versatility. With various grades of steel available in the market today, it is essential to understand the different properties of each grade before making a buying decision. This blog post will focus on the differences between two popular steel grades – 1070 and 1074. Read on to learn more about these two steel grades and their differences.

What is 1070 Steel?

1070 Steel is a type of high-carbon steel alloy comprised of carbon and iron. It’s highly durable and malleable, making it an ideal material for tools like cutlery and blades. Due to its hardness and low cost, it’s popularly used in construction projects such as springs, axles and high-strength wires. Its tensile strength enables it to maintain stability even under extreme temperatures or pressures, thus allowing stronger bonds in welded joints that produce more reliable structures.

What is 1074 Steel?

1074 steel is a high-carbon alloy that is often used in the production of swords and knives. Its composition consists of 0.75–0.85% carbon, 0.60–0.90% manganese, 0.40–1.00% silicon, and less than 0.040 phosphorus and sulfur each. This combination gives it excellent wear resistance and superior tensile strength when compared to other steels commonly used in knife making, such as 440C or Damascus steel, providing an excellent balance between hardness and toughness while still maintaining good corrosion resistance at room temperature conditions with proper care & maintenance processes applied to the blade surface itself over time as well as its edges sharpened regularly during use/application cycles for best results! It is one of the finest alloys available for cutting tools today!

Difference Between 1070 Steel and 1074

1074 steel has a higher carbon content than 1070 steel, making it stronger and harder. It is also more machinable and retains its hardness at higher temperatures. 1074 steel is ideal for parts that require strength, high wear resistance or are subject to shock or vibrations.

Carbon Content

1070 steel and 1074 steel are both high-carbon steels, meaning they contain more carbon than others. The 1070 steel contains 0.7% carbon, while the 1074 steel contains 0.74% carbon. This carbon content difference gives each of these steels unique properties and characteristics.


The higher the carbon content, the harder the steel will be. As a result, 1070 steel is slightly softer than 1074 steel, with a hardness rating of approximately 54-60 HRC compared to 58-64 HRC for 1074 steel. This difference in hardness makes 1070 steel better suited for applications that require flexibility, while 1074 steel is better suited for applications that require strength and durability.

Corrosion Resistance

Both 1070 and 1074 steels have excellent corrosion resistance due to their high chromium content. However, 1074 has slightly better corrosion resistance due to its higher carbon content which helps it form a protective layer on its surface when exposed to moisture or air. This protective layer helps prevent rust and other forms of corrosion from forming on the surface of the metal.

Heat Treatment

When heat treating either 1070 or 1074 steel, it is important to note that they will respond differently depending on their composition and manufacturing. For example, 1070 steel may become brittle if not heat treated properly, while 1074 may become too hard if not heat treated properly. Hence, it’s important to understand how each type of steel responds before beginning any heat treatment process.


Due to their differences in hardness, corrosion resistance, and heat treatment response, 1070 and 1074 steels are used for different applications. 1070 is typically used for knives or tools that require flexibility, such as swords or machetes, while 1074 is often used for knives or tools that require strength, such as axes or hatchets


In conclusion, 1070 and 1074 steel grades have specific uses and applications. While 1070 steel has exceptional hardness and tensile strength, 1074 steel is best suited for applications that require heat treatment and superior machinability. If you are in the market for high-carbon steel, it is essential to understand the differences between each steel grade, as choosing the right one can make all the difference in the performance of your final product. Always seek a professional’s advice before deciding on the type of steel to purchase.
