CarTech H-46 is a martensitic, 12% chromium steel designed primarily for high strength applications in the 900/1200°F (482/649°C) temperature range.

The creep resisting properties of this alloy compare favorably with those of several of the lower grades of austenitic, heat resisting steels in the 1000/1200°F (538/649°C) temperature range.

CarTech H-46 exhibits low thermal expansion properties. This has been a factor for its consideration for use in structural applications where standard austenitic stainless steels have been inadequate due to excessive expansion when heated.

Applications:
CarTech H-46 has been used in compressor blades and rotor discs in jet aircraft engines, as well as in other applications requiring high strength in the 900/1200°F (482/649°C) temperature range.
