EN19 Rolled Rounds – The Industry Standard for Strength and Machinability

EN19, as per BS970:1955, is a medium carbon chromium-molybdenum alloy steel known for its high tensile strength, excellent wear resistance, and superior toughness. Steelmet Industries offers EN19 rolled round bars in diameters ranging from 16mm to 200mm, available in multiple conditions including as-rolled, softened/annealed, and machinable formats.

These bars are widely used in automotive, machinery, forging, and precision engineering industries across India and international markets.


Key Characteristics of EN19 Rolled Rounds

  • Standard: BS970:1955

  • Grade: EN19

  • Composition (approx.): C 0.35–0.45%, Cr 0.9–1.2%, Mo 0.2–0.35%

  • Condition: Rolled, Annealed, Rough Machined

  • Heat Treatable: Yes – widely used in Q&T condition

  • Hardness Range: Can be hardened up to 58 HRC after treatment

  • Machinability: Good in annealed condition

  • Weldability: Moderate – requires precautions


Common Applications of EN19 Rolled Bars

EN19 is a versatile and highly demanded alloy steel used in:

  • Automotive Parts: Axles, shafts, pinions, gears

  • Industrial Equipment: Couplings, spindles, lifting parts

  • Machine Tools: Tool holders, arbors, fixture components

  • Forgings & Heat Treated Components: Crankshafts, connecting rods

  • Hydraulic Machinery: Pistons, rods, sleeves

EN19 combines strength and ease of processing, making it ideal for post-machining heat treatment.
