Marzouk Steel is a dependable manufacturer and supplier of Carbon Steel EN-353 Bars in Tunis, Tunisia, offering materials engineered for strength, toughness, and long-term performance. EN-353 is a low-alloy case-hardening steel widely valued for applications that demand a hard, wear-resistant surface combined with a tough core. At Marzouk Steel, our EN-353 bars are produced with strict quality control to ensure consistent chemistry, excellent machinability, and reliable heat treatment response. We take pride in supplying EN-353 bars that meet international standards while supporting our customers with timely delivery and practical technical guidance.
Carbon Steel EN-353 Bars typically contain low carbon content along with alloying elements such as nickel, chromium, and molybdenum, which enhance strength, toughness, and hardenability. This composition makes EN-353 ideal for case hardening processes like carburizing. Mechanically, EN-353 bars offer good tensile strength, high core toughness, and excellent fatigue resistance after heat treatment. The hardened surface provides superior wear resistance, while the inner core remains ductile, ensuring durability under repeated stress and load conditions.
