Arne Steel
Steel name: Arne
Diagram No.: 2733
Mat.No. (Wr.Nr.) designation: 1.2510
AISI/SAE designation: O1
Chemical composition in weight %: 0.95% C, 0.30% Si, 1.10% Mn, 0.60% Cr, 0.10% V, 0.55% W
Steel group: Cold work tool steels
Properties: Uddeholm Arne general purpose oil-hardening tool steel is a versatile manganese-chromiumtungsten steel suitable for a wide variety of cold-work applications.
Applications: These characteristics combine to give a steel suitable for the manufacture of tooling with good tool life and production economy. Uddeholm Arne can be supplied in various finishes including hot-rolled, pre-machined, fine-machined and precision ground. It is also available in the form of hollow bar.

Heat Treatment
Hardening: Preheating temperature: 600–700°C (1110– 1290°F) Austenitizing temperature: 790–850°C (1450– 1560°F). Quenching media: High speed gas/circulating atmosphere. Vacuum (high speed gas with sufficient positive pressure). An interrupted quench is recommended where distortion control and quench cracking are a concern. Martempering bath or fluidized bed at 450– 550°C (840–1020°F), then cool in air. Martempering bath or fluidized bed at 180–220°C (360–430°F) then cool in air. Warm oil.
Tempering: Choose the tempering temperature according to the hardness required by reference to the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (360°F). Holding time at temperature minimum 2 hours.
Diagram note: Bellow tempering curves are obtained after heat treatment of samples with a size of 15 x 15 x 40 mm, quenched in oil. Lower hardness can be expected after heat treatment of tools and dies due to factors like actual tool size and heat treatment parameters.
