20h2n4a alloy steel is available in thicknesses ranging from 2mm to 120mm, with a length tolerance of +/-2 mm. If you need a different steel grade or custom dimensions, our team is ready to provide a tailored offer—just contact us directly.Orders for this product are made on request. The typical production time is about 1 month, with preparation for shipment taking 2-3 working days. Delivery times may vary depending on the parcel service; please refer to our FAQ for more details.20h2n4a is a chromium-nickel alloyed structural steel, also known as 12xh3a. The material consists of approximately 0.20% carbon, 2% chromium, 4% nickel, and is recognized for its very high steel quality.Key properties of 20h2n4a include excellent plastic deformability, high core toughness, and impressive surface hardness, making it suitable for components exposed to high impact loads or low temperatures. However, the steel has limited weldability—preheating to 200-300°C is required, followed by annealing after welding to ensure optimal results.Common applications include the production of gears, gear shafts, and gudgeon pins. As a trusted supplier, Evek GmbH offers worldwide shipping of GOST-certified 20h2n4a steel in various sizes and shapes.Main characteristics: - Excellent plastic deformability - High core toughness - High surface hardness - Limited weldabilityChemical composition (in %): - C: 0.16–0.22 - Si: 0.17–0.37 - Cr: 1.25–1.65 - Mn: 0.3–0.6 - Ni: 3.25–3.65 - S: 0.025 - P: 0.025 - Cu: 0.3Buy 20h2n4a steel from Evek GmbH for quality materials tailored to your requirements.
