Delivery times may vary depending on the parcel service—please refer to our FAQ for more details. 12hn3a is a chromium-nickel alloyed structural steel. Its designation means: - 12: 0.12% carbon content - H: around 1% chromium - N3: about 3% nickel - A: very high steel quality This material offers high strength and good plastic deformability, with excellent impact strength at low temperatures. The presence of chromium and nickel provides good mechanical properties and high hardenability, though its weldability is limited. 12hn3a round steel is widely used in the production of highly stressed components operating at low temperatures (down to -100 °C) and requiring high strength, such as: - Gear wheels and shafts - Worm gears - Axles - Elastomer couplings - Piston pins Key features of 12hn3a include: - Limited weldability (manual arc and TIG welding) - High strength - Good plastic deformability - Excellent impact strength at low temperatures - High hardenability As a reliable supplier, we provide 12xh3a and other GOST steels worldwide at competitive prices.
