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.
