Hardness Ratings (HRC) in Tool and Die Steel
Virat Steels | India's Leading Tool and Die Steel Supplier If you've ever looked at a tool steel datasheet and wondered what "58 HRC" means and why it matters for your die or mould. Hardness is one of the most critical properties in tool and die steel selection. Get it right, and your tooling performs reliably for thousands of production cycles. Get it wrong, and you're facing premature wear, unexpected cracking, or both. This complete blog explains what is the Rockwell C scale means, maps HRC ranges to every major tool steel grade, and shows you exactly how to choose the right hardness for your application. What is Hardness in Steel and Why Does It Matter? In simple terms, hardness is a material’s ability to resist dents, scratches, or permanent deformation under pressure. For tool and die steel, hardness is one of the most important properties because it affects: · Wear resistance – resists abrasion ...
