ASSAB Caldie
Caldie is a chromium-molybdenum-vanadium alloyed tool steel which is characterized by:
- Very good chipping and cracking resistance
- Good wear resistance
- High hardness (>60 HRC) after high temperature tempering
- Good dimensional stability during heat treatment
- Excellent through-hardening properties
- Good machinability and grindability
- Excellent polishability
- Good surface treatment properties
- Good resistance to tempering back
- Very good WEDM properties
Applications
Caldie is suitable for short to medium run tooling where chipping and/or cracking are the predominant failure mechanisms and where a high compressive strength (hardness of over 60 HRC) is necessary. This makes Caldie an excellent problem solver for severe cold work applications where the combination of a hardness above 60 HRC and a high cracking resistance is of utmost importance e.g. as in the blanking and forming of ultra high strength steel sheets.
Caldie is also very suitable as a substrate steel for applications where surface coatings are desirable or necessary.
Typical Applications
- Blanking
- Cold forging and forming
- Machine knives
- Thread rolling dies
- Substrate for surface coatings
- Fragmentation knives for plastics and metals
- Roll forming rolls
