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

Carbon Steel EN-31 R-100 Bars primarily consist of carbon (around 1.0%) and chromium (approximately 1.0–1.2%), along with small amounts of manganese and silicon. These elements contribute to the steel’s remarkable strength, wear resistance, and hardenability. Mechanically, EN-31 bars showcase excellent tensile strength (700–950 MPa), good toughness, and high surface hardness after heat treatment. This material maintains its structural integrity under stress and has a moderate elongation percentage, making it ideal for high-load and precision-machined components.
