D2 Steel is a high-carbon, high-chromium tool steel known for high wear resistance, hardness, and compressive strength. When modified as Cr12MoV, it includes molybdenum (Mo) and vanadium (V), which improve toughness, hardenability, and wear resistance compared to standard D2. This steel is ideal for cold work tooling, dies, punches, shear blades, and other high-stress applications where both wear resistance and moderate toughness are required.

• High wear resistance due to high chromium content (~12%)

• Moderate toughness enhanced by molybdenum and vanadium

• Excellent dimensional stability during hardening and heat treatment

• High compressive strength

• Suitable for cold work tooling, blanking, forming, and cutting tools

1. Preheat: 650 – 700°C

2. Austenitizing / Hardening: 1020 – 1050°C, oil or air quench depending on size

3. Tempering: 150 – 250°C (for high hardness), or 500 – 550°C (for higher toughness)

4. Annealing (for machining): 840 – 880°C, slow furnace cooling

• Cold work dies and punches

• Shear blades and cutting tools

• Forming and bending tools

1020 Round Bar is a low-carbon steel bar commonly used in applications that require moderate strength and excellent weldability, machinability, and ductility. It’s a versatile steel suitable for general-purpose engineering, especially in the manufacturing of components like shafts, pins, and machined parts.

• Grade: AISI 1020 (also referred to as C20 in some regions)

• Type: Low-carbon steel

• Form: Supplied in round bar, flat bar, square bar, hexagonal bar, etc.

• Key Features:

  • Low carbon content (~0.20%) gives excellent weldability and machinability

  • Moderate strength and good toughness

  • Widely used in manufacturing and fabrication applications

🔍 The low carbon content makes 1020 steel more ductile and easier to weld, but it limits its hardenability.

💡 1020 steel has moderate strength, which is ideal for components not requiring high tensile strength but need high ductility and impact resistance.

• ✅ Excellent weldability

• ✅ Good machinability, especially when cold-drawn

• ✅ High ductility and toughness

• ✅ Suitable for applications where hardening isn’t necessary

• ⚠️ Not suitable for high-strength applications where wear or fatigue resistance is critical

• Shafts: For light loads or in low-stress applications

• Pins: Used in machinery and automotive applications

• Automotive Parts: Components like bolts, bushings, and frames

• Machined Parts: Low-load components like fasteners and hardware

• Furniture: For structural or decorative parts

• Structural Components: In light-duty construction or framing

1020 can be heat-treated to improve its hardness and machinability:

1. Annealing: Heat to 870-910°C and allow to cool slowly.

2. Normalizing: Heat to 870-920°C and air cool to refine grain structure.

3. Case Hardening (for wear-resistance applications): Carburizing can give a hard surface with a tough core.

4. Cold Working: Increases strength slightly but decreases ductility.

📌 1020 has limited hardenability due to its low carbon content, so it’s typically not used for high-strength, hardened components.
