SKT6 die casting mold steel is a high-quality alloy tool steel that is widely used in the manufacture of die casting molds. Due to its excellent wear resistance, heat resistance and toughness, SKT6 is an ideal choice for manufacturing die casting molds. This article will introduce in detail the characteristics, applications and comparison of SKT6 die casting mold steels with other mold steels.
1. Characteristics of SKT6 die-casting mold steel.
1.Excellent wear resistance: SKT6 die casting mold steel has excellent wear resistance after special heat treatment and alloying element addition. In the die casting production process, the mold is subjected to extremely high pressure and friction, so wear resistance is an important performance indicator of steel for die casting molds. The wear resistance of SKT6 is better than that of traditional carbon tool steel and high-speed steel, which can significantly improve the service life of the mold.
2.Excellent heat resistance: During die casting production, the mold temperature rises dramatically. SKT6 die casting mold steel has very good heat resistance, able to maintain high hardness and good mechanical properties at high temperatures. This helps to reduce thermal fatigue, reduce the risk of mold cracking, and improve the stability and reliability of the mold.
3.Good toughness: SKT6 die-casting mold steel has good toughness, which can absorb impact energy and improve the fracture resistance of the mold. During die casting production, molds can be subjected to shocks and collisions, so toughness is essential to prevent mold cracking and extend service life.
4.Excellent machinability: SKT6 die-casting mold steel has excellent cutting performance and is easy to perform machining operations such as drilling, milling and grinding. This helps to streamline the mold manufacturing process, improve production efficiency, and reduce manufacturing costs.
Second, the application of SKT6 die-casting mold steel.
1.Automobile manufacturing industry: Automobile manufacturing industry is one of the important application areas of die casting molds. SKT6 die-casting mold steel is widely used in the manufacture of die-casting molds for automobile engines, chassis, brake systems and other parts. Due to its wear-resistant, heat-resistant and toughness, SKT6 can significantly improve the service life of molds, reduce maintenance costs and improve production efficiency.
2.Home appliance manufacturing: Home appliance manufacturing is also one of the important application areas of die-casting molds. SKT6 die-casting mold steel is widely used in the manufacture of die-casting molds for parts of household appliances such as washing machines, refrigerators, and air conditioners. In the home appliance manufacturing industry, SKT6 can meet the production requirements of high efficiency, high precision and high quality, and improve the service life and stability of molds.
3.Other manufacturing industries: In addition to automobile and home appliance manufacturing, SKT6 die-casting mold steel is also widely used in communications, electronics, construction, aerospace and other manufacturing fields. In these areas, SKT6 is able to meet the needs of die casting mold manufacturing with a wide range of complex shapes and high performance requirements.
3. Comparison with other die steels.
Compared with other mold steels, SKT6 die casting mold steels show excellent performance in terms of wear resistance, heat resistance, and toughness. Here's how it compares to several other common die steels:
1.Comparison with carbon tool steel: Although carbon tool steel is cheap, it has poor wear resistance and heat resistance. In the die casting production process, carbon tool steel is prone to wear and deformation, resulting in a short mold life. In contrast, SKT6 die casting mold steel has better wear and heat resistance, which can significantly improve the service life of the mold.
2.Comparison with High Speed Steel: High speed steel is a high-alloy tool steel with excellent red hardness and wear resistance. However, high-speed steel has poor toughness and is prone to brittleness. When subjected to impact or collision, HSS molds are prone to cracking. In contrast, SKT6 die casting mold steel has better toughness and heat resistance, and is able to maintain stable mechanical properties at high temperatures.
