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 of0.5 % 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 contentcontributes 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 result
of 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 of10 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,di es,rotar y gear shaping and shaving cutters for the processing of hard materials, hexagon socketpunches and piercing dies for the nutproducti on.
