Carbon Steel EN-31 R-100 Bars are characterized by their high carbon content and chromium, which contribute to their impressive hardness, wear resistance, and strength. These bars boast high tensile strength and exceptional resistance to abrasion, making them ideal for heavy-load and high-stress environments. They can be hardened and tempered to enhance durability and toughness while ensuring dimensional stability. Additionally, EN-31 R-100 shows decent machinability in its annealed state and achieves high surface hardness after heat treatment. These mechanical properties make it a go-to choice for precision components that require both strength and wear resistance.
