Assab Steels 8407 SUPREME Hot Work Steel
Categories: Metal; Ferrous Metal; Chrome-moly Steel; Tool Steel; Hot Work Steel

Material Notes: 8407 SUPREME is characterized by:
  • High level of resistance to thermal shock and thermal fatigue
  • Good high temperature strength
  • Excellent toughness and ductility in all directions
  • Good machinability and polishability
  • Excellent through-hardening properties
  • Good dimensional stability during hardening

The name "SUPREME" implies that by special processing techniques and close control, the steel attains high purity and a very fine structure. Further, 8407 SUPREME shows significant improvements in isotropic properties compared to conventionally produced AISI H 13 grades.

These improved isotropic properties are particularly valuable for tooling subjected to high mechanical and thermal fatigue stresses, e.g. die casting dies, forging tools and extrusion tooling. In practical terms, tools may be used at somewhat higher working hardness (+1 to 2 HRC without loss of toughness. Since increased hardness slows down the formation of heatchecking cracks, improved tool performance can be expected.

8407 SUPREME meets the North American Die Casting Association (NADCA) #207-90 for premium high quality H-13 die steel.

Applications: Tools for Die casting: Dies, fixed inserts cores, sprue parts, nozzles, ejector pins (nitrided), plunger, shot-sleeve (normally nitrided).
Tools for Extrusion: Dies, backers, die holders, liners, dummy blocks, stems.
Tools for pressing Aluminum, magnesium, copper alloys, and steel.
Molds for plastics: Injection molds, compression/transfer molds.

Premium AISI H13, W.-Nr. 1.2344
