EN 10083-2 1.0540 Material Mechanical Properties
The mechanical properties of EN 10083-2 1.0540 steel are defined through a variety of tests, including tensile strength, yield strength, elongation, impact strength, and hardness. Tensile strength refers to a material's ability to resist fracture under tension, while yield strength is the amount of force necessary to cause the material to deform. Elongation measures the amount of strain the material can withstand before it fractures, and a harder material indicates better wear resistance.
