High-Speed Steel
SIRAPID 3348, a high-speed molybdenum alloy tool steel, is commonly used in the production of cutting tools for machining operations, including segment and circular cutters, profile cutting tools, and thread cutting drills. Its high wear resistance and ability to maintain hardness at elevated temperatures make it ideal for demanding applications such as Sendzimir rolls and cold forming tools.
