EN 10084 16NiCrS4 is a nickel-chromium alloy carburizing steel with controlled sulphur content, designed for components requiring a hard, wear-resistant surface combined with a tough and impact-resistant core after carburizing and heat treatment. With approximately 0.16% carbon along with nickel and chromium additions, this grade offers excellent hardenability and core strength, while the sulphur addition improves machinability compared to 16NiCr4. Manufactured in accordance with EN 10084, which specifies technical delivery conditions for steels intended for carburizing treatment, 16NiCrS4 steel is widely used in automotive, heavy engineering, and transmission industries. The nickel improves toughness and fatigue resistance, chromium enhances depth of hardening and wear resistance, and the sulphur addition ensures efficient machining prior to heat treatment. Ladhani Metal Corporation is a trusted manufacturer, supplier, and exporter of EN 10084 16NiCrS4 round bars, supplied with mill test certificates and strict quality inspection as per European standards. Forms of Supply (as per grade): Hot rolled round bars, Black round bars, Bright round bars, Peeled bars, Turned bars, Ground bars, Forged round bars Explanation of Designation (16NiCrS4): • 16 – Approx. 0.16% carbon content • Ni – Nickel alloyed steel • Cr – Chromium alloyed steel • S – Increased sulphur content for improved machinability • 4 – Alloy content classification Chemical Composition (% – typical limits): • Carbon (C): 0.14 – 0.19 • Manganese (Mn): 0.50 – 0.80 • Silicon (Si): ≤ 0.40 • Nickel (Ni): 0.90 – 1.20 • Chromium (Cr): 0.60 – 0.90 • Phosphorus (P): ≤ 0.025 • Sulphur (S): 0.020 – 0.040 Mechanical Properties (Core, typical normalized condition): • Tensile Strength: 750 – 950 MPa • Yield Strength: ≥ 500 MPa • Elongation: ≥ 10% • Hardness (Core): 200 – 260 HB After carburizing and quenching, the surface hardness can reach approximately 58 – 62 HRC, depending on case depth and heat treatment conditions. Key Features: • Excellent carburizing response • Improved machinability due to controlled sulphur content • Good hardenability from chromium content • High core toughness due to nickel addition • Enhanced fatigue and impact resistance Material Characteristics: EN 10084 16NiCrS4 round bars combine strong hardenability with enhanced machining performance. The nickel addition improves ductility and resistance to shock loading, chromium supports uniform case depth, and sulphur allows efficient machining before carburizing and heat treatment. Applications: • Gears and gear shafts • Transmission components • Drive shafts and axles • Pinions and sprockets • Automotive drivetrain parts • Industrial machinery components requiring case hardening Conclusion: Ladhani Metal Corporation supplies high-quality EN 10084 16NiCrS4 round bars in various diameters and finishes. With reliable hardenability, improved machinability, and strong mechanical performance, 16NiCrS4 steel is widely used in automotive and industrial engineering applications.
