Shalan Steel, based in Kuala Lumpur, Malaysia, stands out as a top-notch manufacturer and supplier of high-quality Carbon Steel EN-45 Bars. These bars are celebrated for their remarkable strength, durability, and versatility. Crafted from premium raw materials and utilizing cutting-edge manufacturing techniques, they offer exceptional mechanical performance and precise dimensions. With their impressive toughness and resistance to fatigue, Carbon Steel EN-45 Bars are a go-to choice in industries like automotive, construction, railways, and general engineering, where safety and efficiency hinge on durability under intense stress.
Carbon Steel EN-45 Bars consist mainly of carbon (0.45%) and small percentages of manganese, silicon, and phosphorus. The composition is designed to provide increased strength, wear resistance, and toughness to the EN-45 bars to enable them for high-demand applications. The mechanical properties are excellent tensile strength (up to 700 MPa), yield strength (about 450 MPa), and hardness, ensuring durable performance. With superior impact and fatigue endurance, EN-45 bars find favor with automotive, construction, and engineering industries with their durability and reliability to perform in heavy-duty conditions.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
These bars boast a high carbon content, complemented by silicon, manganese, and chromium, which boosts their wear resistance, hardness, and tensile strength. This unique composition makes them perfect for heat treatment processes, such as hardening and tempering, which further enhance their strength, elasticity, and performance when faced with dynamic loads.
