EN 1.4024 stainless steel is a martensitic stainless steel formulated for primary forming in forged products . EN 1.4024 - is the numerical for this material and EN X15Cr13 is the chemical designation .
It has a moderately low structured energy among forged martensitic stainless steels in the database .
Corrosion resistance
Does not have very good corrosion resistance, 1.4024 quality will withstand mild atmospheric conditions and fresh water well.
Machinability
While 1.4024 grade materials can be machined in the annealed state, they tend to perform better in the cold drawn or heat treated state.
Weldability
The most common welding methods can be used successfully with this alloy. It is recommended to preheat the workpiece to 177-204oC to reduce the possibility of cracking. Post-weld annealing is recommended to achieve maximum ductility .
