1.2344 Tool Steel: The Logic Behind the Industry Standard & A Guide to Precision Selection

Over 80% of aluminum extrusion dies utilize 1.2344 (H13) steel. This prevalence is rooted in its optimal balance of performance and cost. Its core advantage lies in the well-rounded properties provided by its Cr-Mo-V alloy system: sufficient hot strength (maintaining hardness at 500-600°C), excellent thermal fatigue resistance to combat heat checking, and good toughness to prevent cracking. This makes it the most reliable and economical choice for the demanding conditions of aluminum extrusion.

However, the performance of 1.2344 varies significantly between different steel mills. The key to selection lies in matching the material to your specific needs.

Core Differences: Composition and Process Dictate Performance
