1095 carbon steel is a high-carbon steel known for its excellent hardness, strength, and wear resistance. It is commonly used in applications requiring high durability and wear resistance, such as tools, knives, and springs. This steel grade has a carbon content of approximately 0.95%, which gives it its distinctive characteristics. While it offers superior hardness, its brittleness also makes it prone to cracking under high impact, requiring proper heat treatment to enhance its properties.
1095 carbon steel is commonly compared to other steel grades, such as 1045 and 1080 carbon steels, for its higher carbon content, which results in increased hardness and strength. Its applications span various industries, from automotive to manufacturing, where durability and precision are paramount. However, while it performs well in many applications, it may not be suitable for all environments due to its vulnerability to corrosion and lack of flexibility.
1. What is 1095 Carbon Steel?
1095 carbon steel is a medium to high-carbon steel that contains 0.90–1.03% carbon. This high carbon content makes it much harder than lower carbon steels, such as 1018 or 1045, but it also makes it more brittle. The main features of 1095 carbon steel include high wear resistance and edge retention, making it ideal for cutting tools and other high-strength applications.
2. Performance and Properties of 1095 Carbon Steel
Mechanical Properties:
-
Hardness: 55-64 HRC (Rockwell Hardness)
-
Tensile Strength: 600-700 MPa (approx.)
-
Yield Strength: 400-600 MPa (approx.)
-
Modulus of Elasticity: 210 GPa (approx.)
1095 carbon steel demonstrates excellent hardness and strength after proper heat treatment, which is a key factor in its successful application in tools and knives. However, its brittleness is an inherent characteristic, limiting its use in applications subject to high impact.
Chemical Composition:
-
Carbon (C): 0.90-1.03%
-
Manganese (Mn): 0.30-0.50%
-
Silicon (Si): 0.10-0.35%
-
Phosphorus (P): 0.03% max
-
Sulfur (S): 0.03% max
This composition provides 1095 carbon steel with a balanced combination of strength, hardness, and wear resistance, but the higher carbon content reduces its ductility.
3. Uses and Applications of 1095 Carbon Steel
1095 carbon steel is widely used for various industrial and manufacturing purposes, including:
-
Cutting Tools: Such as knives, blades, and scissors due to its edge retention.
-
Springs: For high-stress applications where high tensile strength is required.
-
Axles and Shafts: For heavy-duty machinery and automotive components.
-
Tools: Such as chisels and drill bits, where durability and strength are essential.
Its wear resistance and hardness make it suitable for high-performance cutting tools, but its brittleness limits its use in situations where flexibility or shock resistance is crucial.
4. Price Comparison Between China, India, and the United States
Here is a price comparison for 1095 carbon steel based on recent market data:
| Region | Price per Ton (USD) |
|---|---|
| China | $800 – $950 |
| India | $850 – $1,050 |
| United States | $1,000 – $1,200 |
Prices vary depending on the market conditions and supplier offers, but generally, 1095 carbon steel is more affordable in China and India compared to the United States, where costs are typically higher due to labor and manufacturing standards.
5. Comparing 1095 Carbon Steel with Other Steel Grades
To understand how 1095 carbon steel compares to other common steel grades, let’s look at the following comparison:
| Property | 1095 Carbon Steel | 1045 Carbon Steel | 1080 Carbon Steel |
|---|---|---|---|
| Carbon Content | 0.90-1.03% | 0.40-0.50% | 0.75-0.85% |
| Hardness (HRC) | 55-64 HRC | 45-50 HRC | 50-60 HRC |
| Yield Strength (MPa) | 400-600 | 350-450 | 400-500 |
| Tensile Strength (MPa) | 600-700 | 500-600 | 550-650 |
| Toughness | Low | Medium | Medium |
As shown, 1095 carbon steel has a higher carbon content, hardness, and tensile strength compared to 1045 and 1080, making it more suitable for high-strength applications. However, this comes at the cost of lower toughness.
6. Procurement Tips for 1095 Carbon Steel
When procuring 1095 carbon steel, it is important to consider the following:
-
Heat Treatment: To optimize its mechanical properties, especially its hardness and strength.
-
Source Reliability: Ensure the supplier adheres to quality standards, such as ASTM or ISO certifications.
-
Supplier Reputation: Consider suppliers with a track record of reliable delivery, such as Luokaiwei, known for its high-quality materials and competitive pricing.

7. Case Study: Using 1095 Carbon Steel in Knife Manufacturing
A prominent knife manufacturer required high-carbon steel for crafting durable and sharp knives. After testing different grades, 1095 carbon steel was chosen for its excellent edge retention and hardness. The steel was heat-treated to the optimal temperature for maximum hardness without compromising too much on brittleness. The result was a series of knives with superior cutting performance and longevity.
