INTRODUCTION
Stainless steels are high-alloy steels, which have high corrosion
resistance when compared to other steels due to the presence of
large amounts of chromium. Based on their crystalline structure,
they are further divided into ferritic, austenitic, and martensitic
steels. Another group of stainless steels are known as
precipitation-hardened steels. They are the combination of
martensitic and austenitic steels.
EN 1.4031 stainless steel is a martensitic stainless steel
formulated for primary forming into wrought products. 1.4031 is the
EN numeric designation for this material. X39Cr13 is the EN
chemical designation.
It has a moderately low embodied energy among wrought martensitic
stainless steels. In addition, it has a moderately high electrical
conductivity and can have a moderately low ductility.
APPLICATIONS
EN X39Cr13 1.4031 can be used for decoration materials, electronic
components, machinery, food processing, heat exchangers and
shipbuilding.
