The flexibility, force-bearing capacity, and long life make steel imperative for many industries. SKD-11 and hot die steel are essential materials for making tools. This article will give us a glance at these two steel types, their characteristics, and their application areas.
SKD 11 Steel
Introduction to SKD-11 Steel:
Tool steel of the SKD-11 type possesses an exceptionally high carbon content and chromium. It exhibits excellent wear resistance, toughness, and edge retention qualities, making it applicable in challenging machining operations. It belongs to the group of cold work tool steels and is commonly employed for producing cutters, die, and mold.
Applications of SKD-11 Steel:
SKD-11 steel finds numerous applications in various industries:
- Cutting Tools: It is generally employed to manufacture high-speed steel cutting tools, viz. drills, milling cutters, and woodwork tools.
- Cold Work Dies: The best material for making cold work dies for forming and shaping materials at or near room temperature is the SKD-11.
- Blanks for Stamping and Forming: The steel produces blanking and forming dies for stamping and metal working.
Exploring Hot Die Steel:
As its name implies, hot die steels are formulated to operate in high-temperature environments such as those associated with hot forming and heat-resistant ones. Such steel has excellent toughness and thermal stability, particularly at high temperatures.
Characteristics of Hot Die Steel:
- High Heat Resistance: Hot die steel is designed for use at elevated temperatures, where it still has adequate mechanical properties.
- Good Toughness: It remains solid and resistant to hit at high temperatures.
- Excellent Hardenability: Hot die steel can be turned into a brittle material by being heated for hardening and tempering on its appropriate hardness.
- Wear Resistance: It provides a reasonable wear-resistant property for high-temperature abrasive wear applications.
Applications of Hot Die Steel:
Hot die steel is commonly used in applications that involve high temperatures and thermal stress:
- Die Casting: Dies are made from hot die steel to die-cast metal as alloys such as aluminum, zinc, and magnesium.
- Forging: It is used in hot die forgings of metals.
- Extrusion: Extrusion dies make such plastics and metal from hot die steel.
- Hot Work Tools: They used it in making hot working tools like hot punches, mandrels, and dies for various applications such as forging, hot rolling, and extrusion.
All In All:
Therefore, SKD-11 and hot die steel are separate steels used for different purposes. On the other hand, SKD-11 is ideal for cold work applications that demand wear resistance and toughness. Compared to cold die steel, hot die steel’s property is applicable for high-temperature areas where the material must retain its mechanical attributes under heat and thermal stress. This knowledge helps to determine the appropriate steel or other materials required for any manufacturing or tool-making project.
