Surface Hardening & Steel Hardness Conversion: The Ultimate Guide | Welleshaft 1.Introduction: What Is Surface Hardening? Steel Surface Hardening is a specialized heat treatment method that enhances a metal’s wear resistance by modifying only its surface, while maintaining core ductility. This process is widely used in industries such as automotive, aerospace, machinery, and tool manufacturing. At Welleshaft, our steel surface hardening services ensure precision, durability, and optimal performance for critical components. 2.Principles and Process of Surface Hardening Surface hardening involves heating the metal and rapidly cooling or altering its surface chemistry. Common methods include: Carburizing: Infuses carbon into the surface. Nitriding: Adds nitrogen at low temperatures. Induction hardening: Uses electromagnetic […]
