What are the differences between tungsten carbide and stainless steel in terms of holding a sharp edge?
Yes, it's true that tungsten carbide scissors blades hold a sharp edge longer than stainless steel.
Tungsten Carbide vs Stainless Steel
Tungsten Carbide
Tungsten carbide is a compound composed of tungsten and carbon. Known for its exceptional hardness, tungsten carbide surpasses the hardness of most steels. This extreme hardness, alongside its resistance to wear and tear, makes tungsten carbide ideal for applications where a sharp edge must be maintained for an extended period. Tools like scissors blades often utilize tungsten carbide due to its durability and long-lasting sharpness.
Stainless Steel
On the other hand, stainless steel is also durable and resistant to rust. However, when it comes to retaining a sharp edge, it falls short compared to tungsten carbide. While stainless steel is a popular choice for various tools and objects due to its corrosion resistance, it does not hold an edge as well as tungsten carbide.
In conclusion, tungsten carbide is superior to stainless steel in terms of maintaining a sharp edge over an extended period. If you require tools or items with long-lasting sharpness, choosing tungsten carbide over stainless steel would be the better option.
