Round Bar plate

S355NL is a type of grain structural steel that boasts excellent mechanical properties and strong resistance to breakage. Round bars crafted from S355NL steel are widely utilized in applications due to their unique features and flexibility.

One notable benefit of S355NL bars is their improved toughness and ability to withstand impacts which're crucial for applications prioritizing safety and dependability. With a minimum yield strength of 355 MPa this steel grade is tailored for use in low temperature environment making it ideal for challenging conditions.

The chemical composition of S355NL steel comprises elements like carbon, manganese, silicon, phosphorus, sulfur and small amounts of alloying elements. This composition significantly influences the steels characteristics such as strength, toughness and weldability.

S355NL round bars find application in constructing pressure vessels, storage tanks, bridges and offshore structures that demand strength and impact resistance. The normalized structure of S355NL steel ensures properties throughout the material reducing the risk of breakage and enhancing its weldability.

S355NL round bars offer formability and machinability facilitating shaping and fabrication into diverse components and structures. Their ability to resist corrosion makes them ideal for use in environment such as offshore environment. S355NL round bars are an option for purposes that require strength, durability and the ability to withstand brittle fractures. Thanks to their properties and ease of welding S355NL steel round bars provide a long lasting and budget friendly option for various industrial and construction ventures.
