What is Carbon Steel EN-31 R-100 Series Bars ?

The EN-31 R-100 grade is a high-carbon steel known for its excellent strength and wear resistance. Its composition includes key elements like carbon, chromium, and manganese, which work together to give it superior hardness. After proper heat treatment, it achieves remarkable mechanical properties, including a high tensile strength and excellent toughness. This makes it an ideal material for components that must endure significant stress and friction without deforming or failing prematurely.
