What is Carbon Steel EN-42 Series Bars ?

Carbon Steel EN‑42 is a medium‑carbon alloy steel containing 0.38–0.45 % carbon, 0.60–0.90 % manganese, and trace amounts of chromium (0.20–0.35 %) and nickel (0.35 %). This leads to enhanced strength, toughness, and hardenability. Mechanical properties usually comprise tensile strength of 650–850 MPa, yield strength in the range of 480 MPa, and elongation of 11–16 %. Quenched and tempered EN‑42 has better wear resistance and fatigue life while retaining good machinability in the normalized condition. It is possible to weld with adequate pre‑ and post‑weld heat treatment. Generally, the alloy provides a good combination of performance and economy.

Carbon Steel EN-42 Bars Uses

EN‑42 carbon steel bars are suitable for parts where intermediate strength, wear resistance, and machinability need to be weighed against each other. Common uses are gears, shafts, axles, couplings, and pinions in automotive, pump, and industrial gearboxes. They are also used for making forging blanks, tool inserts, and hydraulic parts in medium-duty applications. Manufacturing, transport, and agricultural machinery industries depend on EN‑42 bars for cost-effective, long‑lasting part production. The ability of the material to support moderate stress, abrasion, and cyclic loading—without losing machinability—makes EN‑42 a material of use across various engineering applications.
