BackgroundTraditionally only wrought material because of its superior
mechanical properties.One of our customers approached us with a need for
– Higher quality for tool steel castings – Reduced leadtimes– Better delivery accuracy
Uddeholm decided to launch a pilot project with this customerResponse from Pilot project customer:
– Leadtimes for tool steel castings is reduced– Delivery-precision is much improved– The quality is better than competitors
Uddeholm decided for 2006 to offer tool steel castings for other automotive customers

Leadtime
Focus on lead time and flexibility Standard lead time is 3 weeks, from arrival of pattern until
shipment from HagforsPattern making adds approximately 1 week to the standard
lead timeClose integration and coordination with external model maker We continuously strive towards even more competitive lead
times and increased flexibilityIt is normally already possible to agree on even shorter lead
times

Quality
A certificate of the chemical analysis and hardness is included for each casting.Simulation of flow and solidificationGood quality raw materialAdvantages for the customer
– Good quality castings – Gives the best possible mechanical
properties– Predictable behavior in machining,
heat treatment etc…Advantages for Uddeholm
– It gives us a stable and predictable production process

Technical Support and R&D
Every day technical support is provided by the staff of the foundry as well as the responsible outdoor salesman.
Uddeholm central R&D can offer technical and metallurgical knowledge and experience as well as testing facilities that conventional foundries do not have
Together with customers Uddeholm has several development projects that aims to increase the knowledge in the field of tool material and sheet metal processing
As an example of this we have now included cast tool steel in our test and research program with SSAB with the aim to find optimalcombinations of tool steel castings and AHSS materials
Another example is the development project of mixed castings

Cast Materials in general compared to wrought steel
No subsequent process steps like for example:– ESR– Hot forging– Rolling
This affects the properties of the material mainly in the following way:– Reduced cleanliness– Reduced ductility– Reduced toughness
The casted materials are in relation to each other similar to the wrought material.
The spread in properties are in general bigger for castings than for wrought steel.
