THYRODUR® 2360 is a 7 % chromium steel that derives its high wear resistance from a balanced combination of the alloying elements.The medium V concentration of 0.5 % generates a sufficiently high hardenability combined with high toughness, even at comparativelylow operating temperatures below RT.
This grade is especially suitable for use with chipper knives, blade holders, veneer slicing blades, blade inserts, billet-shear blades andreinforcements. All require a combination of high hardness and toughness as do large cold extrusion tools of complex geometry.

High-performance high-speed steel featuring an extremely good cutting edge retention and wear resistance due to its high vanadium content. A high cobalt content contributes to a high red hardness and tempering resistance.
Machining of hard materials which wear cutting edges such as highly quenched and tempered chromium-nickel grades and non-ferrousmetals, mother-of-pearl, paper, hard rubber, synthetic resins, marble, slate and the like. Ideally suited for turning and finishing tools,forming tools of all kinds, heavy-duty milling cutters and automatic lathes.

High-carbon, high-speed steel based on molybdenum. Characterized by high wear resistance, red hardness and toughness. As a resultof its low vanadium content, this grade exhibits good grindability.
For tools subject to severe mechanical wear (e.g. in case of small cross-section cuts at high cutting speeds). Particularly suitable for die-sinking cutters, milling cutters and engraving machines including gravers as well as for tool bits in automatic lathes. Also suitable fornon-cutting shaping (e.g. cold extrusion rams and tools employed in machining materials for the aviation industry such as titaniumalloys).

1 For cold-forming tools of a complex geometry, a hardening temperature at the lower end of the quoted range is recommended.The stated hardening temperatures apply to saltbath hardening only. For vacuum hardening, we suggest a reduction of 10 to 30 °C.
Very similar composition to THYRAPID® 3343, but with substantially higher V and C content, resulting in combined maximum wear resistance and cutting edge retention with good toughness.
Taps, reamers, heavy-duty milling cutters, dies, rotary gear shaping and shaving cutters for the processing of hard materials, hexagon socketpunches and piercing dies for the nut production.
