EN 10225 1.8806 + N Introduce
The EN 10225 standard is incredibly important for industries such as the offshore expeditions and machinery production. This is the standard that must be used for materials that adhere to structural criteria for the offshore industry and since offshore components are very expensive, it is important that the materials used in their construction adhere to this standard. The EN 10225 standard is an important standard that is necessary to ensure that these materials meet certain requirements, such as weldability and fatigue, which makes them more durable and reliable. As offshore components are often used in extreme conditions, such as salt water, the EN 10225 standard is necessary to ensure that they will be able to stand up to these conditions.

EN 10225 1.8806 + N Material Machining Technology
One of the benefits of EN 10225 1.8806 + N steel is its good corrosion resistance, but for some applications this may not be enough. In these cases, surface treatments can be used to further improve the alloy's corrosion resistance. These treatments can include different coating methods, such as galvanizing or painting, as well as stainless-steel finishing. These treatments can help to further protect the steel from corrosion and improve its durability in corrosive environments.
