1.2343 (H11) is a type of hot work tool steel that contains approximately 5% chromium, widely used in applications requiring high temperature and impact resistance. Compared to H13 (1.2344), 1.2343 has a lower alloy content, thus possessing:

Higher toughness

Better resistance to thermal fatigue

Lower wear resistance and dimensional stability

This steel grade has excellent dimensional stability during hot processing, which can effectively reduce distortion, suitable for applications requiring high tool life and stability.
