1075 vs 1095 Spring Steel – What’s the Difference?

Many of our customers ask us such a question: 1075 vs 1095 Spring Steel – what’s the difference? Today, in this article, we will delve into the comparison between 1075 and 1095 spring steel, two grades that are commonly used in knife-making and other high-stress applications.

1075 vs 1095 Spring Steel – What’s the Difference?

1075 vs 1095 Spring Steel – 1. Definition

1075 spring steel is a medium-carbon steel grade that offers good strength and toughness combined with relatively easy machinability. It contains approximately 0.75% carbon, which is higher than the carbon content of low-carbon steels but lower than that of high-carbon steels. This carbon content gives 1075 steel its characteristic balance of hardness and ductility.

1095 spring steel is a high-carbon steel grade with a carbon content of approximately 0.95%. This higher carbon content gives 1095 steel its characteristic high hardness and wear resistance, making it a popular choice for knives and other cutting tools.

1075 vs 1095 Spring Steel – 2. Properties

Properties of 1075 Steel:

• Hardness and Strength: 1075 steel can be heat-treated to achieve a hardness of approximately 58-60 HRC (Rockwell Hardness), which makes it suitable for many applications that require resistance to wear and abrasion.
• Toughness: Its medium carbon content gives it good toughness, meaning it can absorb significant impact energy without breaking.
• Machinability: 1075 steel is relatively easy to machine, weld, and form into complex shapes, which makes it a popular choice for knife-making and other manufacturing processes.
• Corrosion Resistance: However, it is not as corrosion-resistant as some other steel grades and may require additional finishes or coatings to protect against rusting.

Properties of 1095 Spring Steel:

• Hardness: 1095 steel can be heat-treated to achieve a hardness of up to 62-64 HRC, making it significantly harder than 1075 steel. This high hardness makes it excellent for applications that require extreme wear resistance and edge retention.
• Strength: Its high carbon content also gives it good tensile strength and resistance to bending and twisting.
• Machinability: However, the higher carbon content makes 1095 steel more difficult to machine and weld than 1075 steel. It is also less ductile and more brittle, which can affect its toughness in certain applications.
• Corrosion Resistance: Similar to 1075 steel, 1095 steel is not particularly corrosion-resistant and may require additional finishes or coatings for rust protection.

1075 vs 1095 Spring Steel – 2. Applications

1075 spring steel is commonly used in knife-making, particularly in the blades of fixed-blade knives and some folding knives. It is also used in other applications where good strength and toughness are required, such as springs, punches, and die sets.

1095 spring steel is widely used in knife-making, particularly in the blades of hunting knives, survival knives, and other cutting tools that require extreme wear resistance and edge retention. It is also used in other high-stress applications such as axes, machetes, and chisels.

Conclusion

In summary, 1075 vs 1095 spring steel both offer good strength and wear resistance but differ in their carbon content, hardness, machinability, and toughness. 1075 steel is a medium-carbon grade that offers a balance of hardness and ductility, making it suitable for applications that require both strength and toughness. 1095 steel, on the other hand, is a high-carbon grade that offers extreme hardness and wear resistance but may be more difficult to machine and weld.
