Lucchini DB6 Tool Steel (DIN 1.2714): Complete Guide to Grades, Properties & Applications in India

Image
  The choice of the appropriate tool steel involves a compromise between hardness, wear resistance, impact toughness, thermal fatigue resistance and the general tool life. While generic steel grades are common, specialized imported tool steels are vital for demanding applications such as hot work, forging and cold stamping. Lucchini Italy is the international reference for ultra-clean tool steels with high durability. Complete guide on technical properties, international & IS standards, manufacturing processes, detailed grade comparison and procurement of tool steel in India. What is Lucchini DB6 Tool Steel? Lucchini DB6 is a low-alloy steel for hot work and impact tools. High Nickel content (1.50″–” 1.80%) formulated and secondary metallurgical refined (EAF->LF->Vacuum Degassing->ESR) This process provides structural purity and minimum non-metallic inclusions with uniform hardenability from core to surface. Material Standards & Cross-Reference DIN / EN Standard: ...

Hot Work Tool Steel: Grades, Properties, Hardness, Heat Treatment & Applications

Image
  Hot work tool steel is designed for one purpose – to resist heat that would ruin common steel. It is the material behind the dies, molds, punches and blades that are hammered and squeezed and repeatedly heated and cooled – in die casting, forging, extrusion, hot stamping and hot shearing. And what makes it different is easy to say and hard to engineer. It keeps its hardness, toughness, strength and dimensional stability, even when it’s hot. The most common grades you’ll come across are H13 (DIN 1.2344) , H11 (DIN 1.2343) and DB6 (DIN 1.2714) — which one you need depends on your operating temperature, impact load, die size and how long you want the tool to last. What Is Hot Work Tool Steel? It’s an alloy tool stee l for tools that get hot and cycle between hot and cold, again and again. It must be a combination of hot hardness, toughness, wear resistance, thermal-fatigue resistance and dimensional stability — all at the same time. The Three Grades You Should Know: H13 / DIN 1.234...
