Welcome to Junaid Metals, your trusted partner in Manama, Bahrain for premium industrial materials. We take pride in supplying high-quality Carbon Steel EN-31 R-100 Bars, specifically engineered for durability and performance. Sourced and distributed with a commitment to excellence, our bars are the ideal choice for industries demanding strength and reliability. We understand the critical nature of your projects and are dedicated to providing materials that meet the most stringent standards, backed by our local expertise and customer-focused service.
The EN-31 R-100 grade is a high-carbon steel known for its exceptional hardness and wear resistance. Its composition includes significant levels of carbon and chromium, which contribute directly to its strength. After proper heat treatment, this steel achieves remarkable mechanical properties, including a high tensile strength and excellent toughness. This specific R-100 condition indicates a spheroidised annealed state, making it ideally suited for subsequent machining and hardening processes, ensuring it meets the demands of high-stress applications.
