Our heat treatment center enables us to be innovative in the heat treatment of our elbows. We have three heat treatment furnaces controlled by a central computer which records all heat treatments for analysis and subsequent documentation.
We are able to subject our elbows to the following heat treatment processes:
All heat treatments are recorded and attached for analysis and later documentation.
Normalizing is a technique used to provide uniformity in grain size and composition throughout an alloy. The material is heated up to a temperature above the transformation point and then cooled down in open air. The aim of this process is to achieve a finer and equal grain size. Afterwards some materials need to be annealed at a temperature of 700-780°C.
Stress relief annealing:
Stress relieving is a technique to remove or reduce the internal stresses created during the forming process. Here the elbow is also heated up to a specific temperature which depends on the type of material, but this is slightly lower than in the normalizing process. Afterwards the elbow is also cooled down in open air.
Solution annealing is a process whereby austenitic stainless steel is heated up to a temperature between 1020°C and 1080°C and the temperature maintained long enough for the carbon to go into solution. After this, the material is quickly cooled in a water bath to prevent the carbon from coming out of solution.
Every heat treatment is recorded. The prepared data will be added to the documentation.
