Frequently Asked Questions

What exactly is silver steel, and why do they call it that?
Silver steel, often known as drill rod, gets its name not from its composition but from its shiny, bright appearance, which resembles silver. This high-carbon steel is well-loved for its versatility and precision in manufacturing tools, dies, and instruments.
How does silver steel differ from regular steel?
Unlike regular steel, silver steel boasts a higher carbon content, making it incredibly hard and durable. This unique composition allows for better wear resistance and the ability to be finely polished, setting it apart in precision applications.
Can silver steel be hardened and tempered?
Absolutely! One of silver steel's standout features is its ability to be easily hardened and tempered. This process significantly enhances its strength and durability, making it ideal for crafting cutting tools and other high-stress components.
Is silver steel corrosion-resistant?
While silver steel excels in hardness and polishability, its Achilles' heel is its lack of inherent corrosion resistance. To combat rust, parts made from silver steel often require protective coatings or must be kept in dry conditions.
What are the common uses of silver steel?
Silver steel shines in the creation of precision tools like drills, taps, and reamers. Its ability to be ground to a tight tolerance also makes it a favorite for dowels, shafts, and bearings in intricate machinery.
