What is Carbon Steel EN-45 Series Bars ?

Carbon Steel EN-45 Bars are medium carbon, silicon-manganese steels, primarily made up of carbon (0.50–0.60%), manganese (0.70–1.00%), silicon (1.50–2.00%), along with trace amounts of sulfur and phosphorus. This unique composition strikes a perfect balance between strength, hardness, and flexibility. In terms of mechanical properties, EN-45 bars boast high tensile strength ranging from 700–900 MPa, good yield strength, and impressive elongation characteristics. They also exhibit outstanding resilience and shock resistance, making them ideal for applications that experience repeated stress. Their machinability and response to heat treatment further boost their performance and lifespan.
