1.2085 / 1.2099 - AT A GLANCE
What kind of steel is the 1.2085 / 1.2099?
As a martensitic steel the 1.2085 / 1.2099 (X33CrS16 / ~X5CrS12) is magnetizable, has good corrosion resistance even in humid conditions and when processing aggressive plastics. 1.2085 / 1.2099 corrosion resistant tool steel comes in a pre-hardened condition, has good machinability and high strength without the need for a heat treatment.
This steel grade can be used when good machinability with simultaneous corrosion resistance is a priority. 1.2085 / 1.2099 has a good ductility and toughness as well as good dimensional stability.
Properties
1.2085 / 1.2099 is a good choice for plastic moulds and offers an excellent combination of corrosion resistance, wear resistance, dimensional stability and machinability. Its good properties give this steel a long service life, a high surface quality and make it low-maintenance.
Practically, this means:
- Plastic mould steel
- Corrosion resistant
- Resistant to agressive plastics
- For environments with high humidity
- Magnetisable
- Good machinability
- Due to the added sulphur the 1.2085 is better to machine compared to the 1.2316
- With a working hardness of approx. 33 HRC at delivery this pre-hardened grade can be used as delivered
- Further heat treatment is not intended
Applications
Applications for this corrosion resistant tool steel include: Blow molds, packaging, electronic industry, measuring gauges, and optical instruments. Due to the better corrosion resistance, the maintenance requirement for molds is reduced. The 1.2085 / 1.2099 can be used for machine parts or medical devices, which are subjected to wear or require regular cleaning or maintenance, due to its hardness and wear resistance.
