Brand3343

High-Speed Steel

SIRAPID 3343, with its enhanced wear resistance and high-temperature stability, is ideal for manufacturing high-performance cutting tools, such as knives, taps, and spiral drills. Its robust toughness and deep hardening response make it particularly suitable for demanding applications in broaching tools, milling cutters, and various woodworking and cold work tools.

Product advantages

SIRAPID 3343 is a higher carbon version of M1 tool steel (Molybdenum High-Speed Tool Steel), offering improved wear resistance compared to M1. It has very high resistance to softening at elevated temperatures, exceptional wear resistance, good toughness, and cutting capability. Additionally, it exhibits a deep hardening response.

Manufacture

SIRAPID 3343 is made by SIJ Metal Ravne.
