Hot-rolled micro-alloyed steel S900MC in accordance with DIN EN 10149-2 is a material with a range of outstanding properties that make it ideal for a variety of applications in construction and mechanical engineering. This article explains the properties and advantages of the S900MC grade, as well as the most important areas of application and information on processing.

Material description and properties
S900MC is a hot-rolled, micro-alloyed steel with a minimum yield strength of 900 MPa. It is characterized by high strength, toughness and wear resistance. The microalloying with elements such as niobium, titanium and vanadium results in a finer grain size and improved hardening, which significantly increases the mechanical properties of the steel.

Important properties of S900MC:
High strength: The minimum yield strength of 900 MPa allows S900MC to be used in highly stressed components.
Good toughness: S900MC is tough and fracture-resistant even at low temperatures.
High wear resistance: The microalloy results in high wear resistance, making S900MC ideal for applications with high abrasive wear.
Good weldability: S900MC is easy to weld and can be processed using all common welding processes.
Good cold formability: S900MC can be cold formed, but its cold formability is somewhat limited compared to unalloyed steels.

Areas of application
S900MC is used in a wide range of applications due to its excellent properties, including

Processing
S900MC can be processed using all standard steel processing methods. When welding, the usual precautions should be observed to ensure an optimum welded joint. The cold formability is somewhat limited compared to unalloyed steels, so the forming conditions should be carefully adjusted.

Standards and approvals
S900MC is standardized according to DIN EN 10149-2. The material number is 1.8798. S900MC is approved for a wide range of applications in construction and mechanical engineering.

Summary
Hot-rolled micro-alloyed steel S900MC in accordance with DIN EN 10149-2 is a material with outstanding properties that is suitable for a wide range of applications. Its high strength, toughness and wear resistance make it an indispensable material in construction and mechanical engineering.
