Materials: Tungsten Carbide and High-Speed Steel


Tungsten steel, also known as Cemented Carbide, is a remarkable material that boasts an impressive combination of properties. It is incredibly hard, highly resistant to wear, and offers exceptional strength and toughness. What truly sets it apart is its ability to maintain these qualities even under extreme conditions. At temperatures as high as 500°C, its hardness and wear resistance remain virtually unchanged, and it continues to perform exceptionally well even at 1000°C.


The secret behind its extraordinary performance lies in its composition. Tungsten steel is primarily made up of tungsten carbide and cobalt, with other metals making up just 1% of its structure. This unique blend gives it unparalleled hardness and wear resistance, making it an ideal choice for demanding applications where durability and reliability are paramount. It’s not just a material—it’s a testament to engineering excellence and innovation.



Difference Between Tungsten Carbide and High-Speed Steel



Chemical Composition



High-Speed Steel (HSS):

High-Speed Steel is a specialized alloy steel that incorporates a variety of carbide-forming elements to enhance its properties. Its key components include tungsten (W), molybdenum (Mo), chromium (Cr), vanadium (V), and cobalt (Co). Each element plays a vital role: tungsten and molybdenum boost hardness and heat resistance, chromium improves corrosion resistance, vanadium enhances wear resistance, and cobalt further increases hardness and performance at elevated temperatures. Together, these elements make HSS a versatile and durable material for high-stress applications.



Tungsten Carbide:

Tungsten carbide, on the other hand, is a composite material primarily composed of tungsten (W) and carbon (C). This combination results in a material with extraordinary hardness and an exceptionally high melting point. The unique bond between tungsten and carbon gives tungsten carbide its legendary wear resistance and durability, making it ideal for applications where extreme hardness and longevity are critical.


In essence, while High-Speed Steel relies on a blend of alloying elements to achieve its balanced properties, Tungsten Carbide stands out for its unmatched hardness and wear resistance, thanks to its simple yet powerful chemical composition. Both materials are exceptional in their own right, catering to different industrial needs with precision and reliability.

In the realm of materials, High-Speed Steel (HSS) and Tungsten Carbide stand as two titans, each with their own unique strengths and characteristics. HSS is a true workhorse, maintaining its hardness up to around 500°C (932°F), a remarkable feat that leaves carbon tool steel in the dust. It's like a sturdy soldier, standing firm against the heat of battle. On the other hand, Tungsten Carbide is the elite warrior, unyielding in its hardness and wear resistance even at scorching temperatures of approximately 1000°C (1832°F). It's no wonder it's the go-to material for applications that demand extreme heat resistance.


When it comes to corrosion resistance, HSS holds its own, thanks to the chromium content that gives it a decent level of protection. However, it's not quite as formidable as stainless steel in this regard. Tungsten Carbide, though, is a different story. Its chemical stability makes it a powerhouse in aggressive environments, offering excellent corrosion resistance that few can match. It's like a shield that remains unscathed even in the harshest of conditions.


In terms of mechanical properties, HSS and Tungsten Carbide each have their own unique advantages. HSS boasts a high tensile strength of around 800-900 MPa, allowing it to shoulder substantial mechanical loads with ease. It's tough and resilient, able to withstand impact and shock without fracturing. Meanwhile, Tungsten Carbide takes it a step further with a tensile strength that often exceeds 1500 MPa. It's the ultimate survivor, enduring extreme stresses with unparalleled durability. However, this comes at a cost—Tungsten Carbide is less tough and more brittle, making it prone to chipping and cracking under impact. In contrast, HSS has a stiffness of around 210 GPa, striking a balance between rigidity and flexibility. Tungsten Carbide, with its stiffness ranging from 530 to 700 GPa, is significantly more rigid but sacrifices some flexibility in the process.

Summary of Material Properties

  • HSS:

    • High hardness (62-67 HRC)

    • Good wear resistance

    • Heat resistant up to 500°C

    • Decent corrosion resistance

    • High tensile strength (800-900 MPa)

    • Good toughness

    • Moderate stiffness (210 GPa)

  • Tungsten Carbide:

    • Very high hardness (85-92 HRA)

    • Superior wear resistance

    • Heat resistant up to 1000°C

    • Excellent corrosion resistance

    • Very high tensile strength (1500+ MPa)

    • Lower toughness, more brittle

    • High stiffness (530-700 GPa).


Selecting the right material based on these properties is crucial for ensuring optimal performance and durability in specific industrial applications.
