EN 10028-3 1.8918 Material Mechanical Properties
EN 10028-3 1.8918 steel is also known for having excellent corrosion resistance. This is due to a few factors. Firstly, its chromium content helps to resist corrosion by forming a thin oxide film on its surface. Secondly, its relatively low carbon content also prevents the steel from rusting easily. Steel with a higher carbon content is more prone to corrosion.
The mechanical properties of the EN 10028-3 1.8918 steel are as follows:
| YieldRp0.2 | ≤ 826 (MPa) |
