Tensile Strength: The maximum tensile stress the steel can withstand before breaking.
Yield Strength: The maximum stress the steel can endure without permanent deformation. This value varies depending on the thickness of the steel in St44 (E275) steel tubes.
Elongation: Indicates how much the steel can stretch before breaking. High elongation indicates that the steel is ductile and better able to withstand shocks.
Hardness: The ability of the steel to resist an applied force on its surface. The Brinell hardness value (HB) indicates the hardness level of the steel.
St44 (E275) steel tubes, thanks to their good mechanical properties and suitable chemical composition, offer a wide range of applications with respect to durability, strength, and machinability.
