1.2550 - AT A GLANCE
What kind of steel is the 1.2550?
1.2550 steel is a tool steel with good dimensional stability, toughness and wear resistance. It has a microstructure that resists deformation when in a tempered state, making it a reliable choice for tools that have to withstand high loads. The steel grade (with a focus on cold work) has a high hardness and impact strength.
Properties
The 1.2550 has advantages and disadvantages that should be taken into account when selecting a steel for certain applications and its specific properties.
Practically, this means:
- Impact resistant
- Robust
- Good wear resistance
- Good heat resistance
- Can be nitrided
- Not corrosion resistant
- Difficult to machine in hardened condition
- Certain properties can only be achieved with a precise heat treatment process
- Working hardness is 56 – 60 HRC
Applications
1.2550 is used for high-impact tools such as punching dies or extrusion dies. This involves applying a great deal of pressure to push the material through a die to create complex shapes. 1.2550 can be used for woodworking tools such as carving tools; particularly for hardwood tools.
