How about the mechanical properties of SAPH440?

SAPH440 exhibits impressive mechanical properties, making it a reliable choice for demanding automotive applications. The key mechanical properties of SAPH440 steel include:

Tensile Strength: SAPH440 has a minimum tensile strength of 440 MPa. Tensile strength refers to the maximum amount of stress a material can withstand before fracturing. With its high tensile strength, SAPH440 ensures structural integrity and robustness, making it suitable for critical automotive components.

Yield Strength: SAPH440 has a minimum yield strength of 275 MPa. Yield strength denotes the stress at which a material begins to deform plastically, typically indicating the onset of permanent deformation. SAPH440’s impressive yield strength ensures that it retains its shape and stability under working conditions, making it highly desirable for automotive applications.

Elongation: SAPH440 exhibits a minimum elongation of 29% for a gauge length of 16 mm or above. Elongation is a measure of a material’s ductility and its ability to deform before fracturing. The significant elongation value of SAPH440 indicates its excellent formability, allowing it to be shaped and manipulated into complex automotive components without compromising its structural integrity.

Bendability: SAPH440 offers a minimum bendability of 180 degrees around a mandrel with a diameter equal to two times the steel thickness. Bendability refers to the ability of a material to withstand bending without fracturing or undergoing significant plastic deformation. SAPH440’s high bendability allows for the fabrication of automotive parts with intricate shapes and contours, enabling greater design flexibility.
