Gost 20h2n4a bar 2-120mm round bar profile round steel bar 0.5-2 meters (length : 1.5 Meter, size : 120mm)

20h2n4a is a high-quality alloyed chromium-nickel structural steel, available in thicknesses ranging from 2mm to 120mm, with a length tolerance of +/-2 mm. If you require specific dimensions or a different steel grade, please contact us and our sales team will provide a tailored offer, either from our stock or delivery program.This steel grade, also known as 12xh3a, is characterized by its chemical composition: approximately 0.20% carbon, 2% chromium, 4% nickel, and a very high steel quality. 20h2n4a offers excellent plastic deformability, high core toughness, and high surface hardness, making it ideal for components subjected to high impact loads or low temperatures, such as gears, gear shafts, and gudgeon pins. Due to its poor weldability, preheating to 200-300 °C and post-weld annealing are recommended for optimal results.Products are made to order, with a production time of about 1 month and preparation for shipment within 2-3 business days. Delivery time depends on the parcel service—please refer to our FAQ for details.As a global supplier of GOST steels, Evek GmbH offers 20h2n4a in various sizes and shapes at competitive prices. The steel’s main features include excellent plastic deformability, high toughness and surface hardness, but limited weldability.
