It has high hardenability and is only conditionally suitable for welding.12hn3a round bar is widely used for manufacturing highly loaded parts that operate at temperatures as low as -100°C, where high strength is required. Typical applications include: - Gears and shafts - Worm gears - Axles - Elastomer couplings - Gudgeon pinsKey properties: - Conditionally weldable (manual arc and TIG welding) - High strength - Good plastic deformability - Excellent impact resistance at low temperatures - High hardenabilityAs a trusted supplier of 12xh3a, we deliver worldwide.
