Carbon Steel EN-19 (V 320) Bars are alloy steels that typically contain around 0.36–0.44% carbon, 0.70–1.00% manganese, 0.15–0.35% molybdenum, and 0.90–1.50% chromium. This unique blend provides outstanding mechanical properties, boasting a tensile strength of 850–1000 MPa, a yield strength of about 680 MPa, and commendable impact resistance. EN-19 bars exhibit high fatigue strength and toughness, even when heat-treated. They also offer good ductility and wear resistance, making them an excellent choice for high-stress applications that require durability, machinability, and a long service life under dynamic loads or harsh conditions.
