Why Is Material Strength Important for Industrial Parts?
Material strength plays a critical role in determining the durability, safety, and performance of industrial parts. When selecting materials for CNC machining, it’s important to understand how different metals like titanium and steel compare in terms of their mechanical properties and their suitability for different applications.
Overview of Titanium and Steel in CNC Machining
Titanium and steel are both popular materials used in CNC machining. Titanium is known for its high strength-to-weight ratio and resistance to corrosion, while steel is celebrated for its toughness and versatility. Understanding the properties of both metals can help you make the best choice for your industrial needs.
Is Titanium Stronger Than Steel?
When comparing titanium to steel, strength is one of the most important factors to consider. However, strength is not the only consideration in determining which material is better for a specific application.

Both titanium and steel are strong materials, but they differ in terms of their strength-to-weight ratios. Titanium is much lighter than steel while maintaining a comparable strength level, making it ideal for applications where weight is a concern, such as in aerospace and automotive industries.
Titanium’s Lightweight Advantage
Titanium’s low density makes it significantly lighter than steel, offering advantages in industries that require strong yet lightweight materials. This is why titanium is widely used in aerospace applications, where minimizing weight without compromising strength is crucial.
Steel’s Tensile Strength
While titanium is lighter, steel is known for its superior tensile strength. Steel’s ability to resist deformation under tension makes it a popular choice for construction and heavy-duty machinery where strength and toughness are paramount.
Which Material Resists Corrosion Better?
Corrosion resistance is a key factor in many industries, particularly in environments exposed to moisture and chemicals. Both titanium and stainless steel have high corrosion resistance, but they perform differently in various environments.
Durability of Titanium in Harsh Environments
Titanium is highly resistant to corrosion, especially in harsh environments such as marine and chemical processing industries. Its ability to withstand extreme temperatures and corrosive chemicals without degrading makes it ideal for these applications.
Stainless Steel’s Corrosion Resistance
Stainless steel, particularly 316 stainless steel, also offers excellent corrosion resistance, especially in mildly corrosive environments. However, in more aggressive environments, titanium often outperforms stainless steel in terms of longevity and resistance to degradation.
Which Is Easier to Machine?
Machining titanium and steel requires different approaches. Titanium is known for its toughness and can be more difficult to machine, requiring specialized tools and techniques. Steel, on the other hand, is more forgiving and easier to machine, but the specific grade of steel and its alloying elements will also impact machinability.
Challenges of Titanium Machining
Machining titanium is challenging due to its hardness and tendency to work-harden during machining. It often requires slow feed rates, high cutting temperatures, and specialized tooling, which can increase production time and costs.
Ease of Steel Machining
Steel is generally easier to machine compared to titanium. With a wider variety of available grades, steel offers more flexibility in machining, and it tends to be more cost-effective due to its easier machinability.
Material Comparison Table: Titanium vs Steel
| Kiinteistö | Titaani | Teräs |
|---|---|---|
| Tiheys | 4,43 g/cm³ | 7.85 g/cm³ |
| Vetolujuus | 434-900 MPa (depends on alloy) | 370-2,000 MPa (depends on grade) |
| Korroosionkestävyys | Excellent (especially in marine environments) | Good (excellent in mild environments) |
| Työstettävyys | Challenging (requires special tools) | Easy (requires common tools) |
| Kustannukset | Higher per unit weight | Lower per unit weight |
Is Titanium Cheaper Than Steel?
When it comes to cost, titanium is generally more expensive than steel, both in terms of raw material costs and machining expenses. However, its unique properties, such as its high strength-to-weight ratio and corrosion resistance, can justify the higher price in certain applications.
Cost Comparison Between Titanium and Steel
While titanium costs more per pound than steel, the overall cost of using titanium depends on the specific application and how much material is required. For industries that prioritize weight savings and corrosion resistance, the higher cost of titanium can be justified.
Raaka-ainekustannukset
The cost of titanium raw material is significantly higher than that of steel, which can increase overall manufacturing costs. However, this cost is offset in applications where the material’s properties provide a competitive edge, such as in the aerospace industry.
Processing and Machining Expenses
Machining titanium is more expensive due to the specialized tools and techniques required. In contrast, steel machining is more cost-effective, and the availability of a wider range of grades allows manufacturers to select the most suitable material for their needs.
Maintenance and Longevity
The maintenance and lifespan of parts made from titanium and steel also differ. Titanium is highly durable and resistant to corrosion, meaning it requires less maintenance over time. Steel, on the other hand, is less expensive but may need more frequent maintenance, especially in corrosive environments.
Titanium’s Long-Term Durability
Titanium’s resistance to corrosion and wear means that parts made from titanium typically last longer than their steel counterparts, making it a better investment in the long term for applications that demand high durability.
Steel’s Affordable Maintenance
Steel parts are often more affordable to maintain, and their durability is sufficient for many industrial applications. However, in environments with high corrosion risk, steel components may need more regular upkeep.

Why Titanium Isn’t Always the “Better” Choice?
Although titanium has many advantages, it isn’t always the best choice. The high cost and machining challenges make it less suitable for certain applications, especially where weight is not a primary concern.
The Right Material for the Right Job: Titanium and Steel’s Strengths
The right material for a given job depends on the specific requirements. If you need lightweight, corrosion-resistant components for aerospace or medical applications, titanium is ideal. If you need a durable, cost-effective material for construction or automotive parts, steel is often the better choice.
FAQs About Titanium and Steel
At What Temperature Does Titanium Lose Strength?
Titanium begins to lose strength at temperatures above 800°C (1472°F). The material’s strength decreases rapidly at elevated temperatures, limiting its use in high-heat applications.
What Is The Lifespan Of Titanium?
The lifespan of titanium depends on the environment and the application. In most cases, titanium parts can last for decades, particularly in industries where corrosion resistance is critical.
Conclusion: How to Choose the Right Material For CNC Machining?
Choosing the right material for CNC machining depends on your specific application requirements. Consider factors such as strength, weight, corrosion resistance, machinability, cost, and maintenance when deciding between titanium and steel. Both materials have their place in industrial machining, and the right choice will depend on your project’s needs.
