EN19 forged rounds in machinable condition are a top choice for critical engineering components that demand high tensile strength, good ductility, shock resistance, and excellent machinability. Typically falling under the BS970:1955 EN19 standard (also known as 709M40 under BS970:1991), this chromium-molybdenum alloy steel offers a fine balance of toughness and strength, making it highly suitable for machining-intensive operations prior to hardening or heat treatment.
At Steelmet Industries, we offer EN19 forged rounds in machinable condition—also known as soft annealed or normalized + tempered condition—in diameters ranging from 40mm to 400mm, with custom size and cut length options, especially suited for applications where pre-machining is critical before final hardening and finishing.

Applications of EN19 Forged Rounds in Machinable Condition
EN19 is widely used across industries due to its adaptability to various heat treatments. Machinable EN19 forged bars are typically used to manufacture:
High-strength automotive shafts, gears, and pinions
Crankshafts, spindles, axles, and connecting rods
General purpose mechanical parts requiring good machinability
Tool holders, jigs, and fixtures
Mining and oilfield components requiring moderate wear resistance
Other Forms & Conditions Available
Steelmet Industries also supplies EN19 in a variety of shapes and finishes:
Bright bars – drawn, peeled, or ground
Flats, Squares, and Custom Profiles
Heat treated – QT (quenched and tempered), N+T, or hardened and tempered
Rough machined or turned finishes
Also available in cut-to-length bars for process-ready delivery

Frequently Asked Questions About EN19 Forged Rounds
Q1: What does “machinable condition” mean for EN19 forged rounds?
A: Machinable condition typically refers to bars supplied in annealed or normalized and tempered condition, where the hardness is low (~200–250 BHN), ensuring easy cutting, turning, and milling.
Q2: Can EN19 forged rounds be used without further heat treatment?
A: Yes, in some cases. However, most applications require hardening and tempering to fully utilize EN19’s high tensile and fatigue strength capabilities.
Q3: Are EN19 and AISI 4140 the same?
A: They are close equivalents in terms of chemistry and performance. Always refer to the project specifications to verify tolerances.
Q4: Do you provide forged EN19 bars with documentation and third-party inspection?
A: Yes. Upon prior agreement, we can supply MTCs, lab reports, inspection documents, and even transport records.
Q5: Do you export EN19 bars?
A: Absolutely. We serve both Indian and international clients with full export documentation and packaging as required.
