EN 10083-1 1.1180 Material Mechanical Properties
EN 10083-1 1.1180 steels display very good corrosion resistance, as the chromium present in the steel helps to form a protective oxide layer on the steel's surface. EN 10083-1 1.1180 steels are particularly resistant to general corrosion and pitting corrosion, making them well suited for nitric acid and other chloride-containing environments. This corrosion resistance makes them ideal for marine engineering, structural applications in the oil and gas industry, and the production of components for the aerospace industry.

EN 10083-1 1.1180 Material Machining Technology
The first step in machining EN 10083-1 1.1180 steel is selecting the most appropriate tool for the job. For most projects, a high-speed steel drill bit is recommended. This type of bit is designed to withstand the extreme heat and pressure generated during the machining process. However, if a greater degree of accuracy is required, other materials such as ceramics, cermets, or diamond-coated bits may be used.
