Product Details:

EN 10083-3 34CrMoS4 is a resulphurized chromium-molybdenum alloy steel grade developed for components requiring high strength, good hardenability, and improved machinability. With a nominal carbon content of approximately 0.34%, this grade offers a strong balance between strength and toughness, while the addition of sulphur (S) enhances machining performance compared to non-resulphurized grades such as 34CrMo4. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10083-3 34CrMoS4 alloy steel bars, supplied with mill test certificates and strict quality assurance.

Forms of Supply (as per grade):
Hot rolled round bars, Black round bars, Forged bars, Bright bars, Peeled bars, Turned bars, Ground bars, Square bars, Flat bars, Hex bars

Explanation of Designation (34CrMoS4):
• 34 – Approx. 0.34% carbon content
• Cr – Chromium for improved hardenability and wear resistance
• Mo – Molybdenum for enhanced strength and resistance to tempering softening
• S – Resulphurized for improved machinability
• 4 – Indicates alloying content range as per EN standard

Chemical Composition (% – typical limits):
• Carbon (C): 0.30 – 0.37
• Manganese (Mn): 0.60 – 0.90
• Silicon (Si): ≤ 0.40
• Chromium (Cr): 0.90 – 1.20
• Molybdenum (Mo): 0.15 – 0.30
• Sulphur (S): 0.020 – 0.040
