Cold work tool steels are specifically designed for applications where tools are used at or below room temperature and require high wear resistance, hardness, and toughness. These steels are commonly used in tools like dies, punches, and cutting tools. They are characterized by high carbon content (1.45% to 2.30%) and the addition of alloying elements like tungsten, molybdenum, chromium, and manganese, which enhance their hardenability and wear resistance. Key Characteristics:

• High Carbon Content:The high carbon content contributes to the steel's hardness and wear resistance. 
• Alloying Elements:Tungsten, molybdenum, chromium, and manganese are added to improve hardenability, reduce distortion during heat treatment, and enhance wear resistance. 
• Hardenability:Cold work tool steels are designed to be readily hardened, allowing them to withstand high compressive stresses and abrasive wear. 
• Wear Resistance:They are known for their excellent resistance to wear, making them suitable for tools that experience significant contact with other materials. 
• Toughness:While not always the primary focus, cold work tool steels also exhibit good toughness, preventing brittle fracture under high impact loads. 
• Low Distortion:The alloying elements help to minimize distortion during the hardening process, which is crucial for maintaining the dimensional accuracy of tools. 

Applications:

• Dies: Blanking, forming, and stamping dies for sheet metal and other materials.
• Punches: Punches for creating holes in various materials.
• Cutting Tools: Knives, blades, and other cutting tools.
• Hand Tools: Tools like hand tools and screwdrivers.
• Fixtures and Gauges: Used in manufacturing processes for holding and measuring components. 

ASTM Standards:

• W (Water Hardening): Examples include W1, W2, and W5.
• O (Oil Hardening): Examples include O1, O2, O6, and O7.
• A (Medium Alloy Air Hardening): Examples include A2, A4, A6, A7, A8, A9, A10, and A11.
• D (High Carbon, High Chromium): Examples include D2, D3, D4, D5, and D7.

P-20+Ni Grade Introduction:DIN 1.2738 steel is one kind of plastic mold steel, equivalent to AISI P20+Ni Tool Steel. While Nickel, chromium, and molybdenum are the alloying elements for hardness and toughness.  1.2738 tool steel is specially designed for the plastic mold industry, especially for big steel mold parts.

• DIN 1.2738 tool steel is usually supplied as pre-hardened/quenched and tempered 280 – 320 HB hardness condition.
• With good machinability, DIN 1.2738 steels are with better polishability compared to 1.2312 (AISI P20+S).
• Material 1.2738 can be through nitrogenation and flame hardening treatment in order to increase the hardness and wearability of the mold surface.

The steel 1.2738 is melted in an electrical furnace and refined with VOD or DH device. P-20+Ni Grade Application:1.2738 mold steel materials are generally used for relatively low-temperature applications such as die-casting dies and injection molds, synthetic plastic molds dies, especially for large plastic molds highly stressed in the core, hydroforming tools, such as up to 400 mm in the construction of plastic molds. DIN 1.2738 is suitable for nitriding and chrome plating. P-20+Ni Equivalent grades:

Die steel blocks are high-strength steel blocks used in metalworking operations like forging, rolling, extrusion, and wire drawing, known for their toughness, wear resistance, and high thermal stability. Here's a more detailed description:Key Features and Applications:

• High Strength and Durability:Die steel blocks are designed to withstand the extreme mechanical and thermal stresses involved in metalworking processes. 
• Toughness and Wear Resistance:They are engineered to resist deformation and wear, even under heavy loads and repetitive use. 
• Heat Resistance:Die steels are often used in hot-working applications, where they must maintain their strength and shape at high temperatures. 
• Machinability and Hardenability:These steels are relatively easy to machine and can be hardened to achieve the desired hardness and wear resistance. 
• Applications:
  • Forging Dies: Used to form heated metal materials into desired shapes. 
  • Die-Casting Molds: Used to cast molten alloys (e.g., aluminum) into intricate shapes. 
  • Hot Stamping Dies: Used to form and quench heated steel sheets. 
  • Cold Press and Forging Dies: Used to form steel plates and blocks at room temperature. 
  • Extrusion Dies: Used to force metal through a die to create long, shaped parts. 

Common Die Steel Grades:

• DIN 1.2714 (DB6): A popular hot-work tool steel known for its toughness, wear resistance, and high thermal stability. 
• H11 and H13: Commonly used chromium hot-work steels, known for their strength, toughness, and resistance to thermal fatigue cracking. 
• Other Grades: D-3, D-2, M-2, M-35, EN-8, EN-9, EN-24, EN-31, EN-353, SAE-8620, SAE-4140.
