DIN 1.2080 

2080 steel is another type of tool steel, known for its high carbon and chromium content. Here are the key characteristics and applications of 2080  steel:

Composition: 

2080 steel belongs to the AISI D series of high-carbon, high-chromium steels. Typical composition includes:

   - Carbon (C): 2.00-2.35%

   - Chromium (Cr): 11.00-13.00%

   - Small amounts of molybdenum (Mo) and vanadium (V) for enhanced properties.

Properties:

   - Hardness: 2080 steel can achieve high hardness after heat treatment, typically around 58-62 HRC.

   - Wear resistance: Excellent wear resistance due to high chromium content.

   - Toughness: Moderate toughness, suitable for applications requiring resistance to chipping and cracking.

   - Dimensional stability: Good dimensional stability in heat treatment.

Applications:

   - Cutting tools: Used for making cutting and stamping dies, blanking and forming tools, shear blades, etc.

   - Molds: Suitable for making cold heading dies, coining dies, embossing dies, and other molds where high wear resistance and toughness are required.

   - Other industrial applications: Can be used in applications where high hardness and wear resistance are critical, such as in industries like automotive, aerospace, and manufacturing.

Heat Treatment : 

2080 steel is typically hardened by heating to around 1010-1040°C (1850-1900°F), followed by oil quenching. This process achieves high hardness levels. Subsequent tempering is done to reduce internal stresses and improve toughness.

Machinability: 

2080 steel has good machinability in the annealed condition but becomes more challenging to machine after heat treatment due to its high hardness.

Overall, 2080 steel is valued for its high hardness, excellent wear resistance, and moderate toughness, making it suitable for a wide range of tool and die applications where cutting and forming tools are subjected to high stress and wear conditions.
