Between hot work tool steel and Carbide, the latter definitely lasts longer. Carbide has some standalone properties, such as resistance to heat and wear. Even the carbide-made tools can retain their hardness. This makes them ideal for applications that need high-speed cutting. On the other hand, hot work tool steel, though having applications that need high temperatures, does not have the wear resistance and hardness of carbides. But there is more to this general perception.
Why does Carbide Last Longer?
There are some obvious reasons why Carbide lasts relatively long than other types of Hot Work Tool steel. To begin with:
- Content of Tungsten Carbide: Tools made from Carbide contain a relatively high content of Tungsten or WC. It has wear-resisting properties. On the other hand, hot work steel primarily has steel alloys.
- Cobalt: Carbide has Cobalt, which is a binder that binds the tungsten grains together. This adds to Carbide's extra strength.
About Microstructure
Tools made from Carbide often have a relatively finer grain structure than that of Hot Work Tools. This improves the overall hardness of the metal and lessons wear. Also, the relatively low porosity of carbides lessons the chance of tool failure or the possibility of crack formation.
Mechanical Matters
The mechanical properties of Carbide also contribute to the longevity of Carbide tools. With a hardness of up to 90 HRA than hot work tool steel, Carbide is more resistant to abrasion and wear. Also, the fact that Carbide undergoes minimal thermal shock makes it tougher. Also, Carbide shows a relatively high level of heat resistance. This also helps in maintaining wear resistance and hardness even amidst the application of a high range of temperatures.
The Best Applications
While hot work tool steel is effective for a range of utilities, its longevity makes it useful for a range of applications. To begin with:
- Carbide-made tools can be a better choice for jobs requiring high-speed cuts.
- Also, the Cobalt content of carbide tools gives extra strength, heat resistance and toughness to various cutting applications.
- The better wear resistance of Carbide makes it a good choice for various applications that involve a high rate of wear and the use of abrasive materials.
When Hot Work Tool Helps
Premier tool manufacturers and suppliers like TGKSSL offer hot work tool steel for specific applications. The team recommends it for applications where maximum thermal shock resistance and toughness are crucial. However, the unique properties of Carbide make it ideal for applications where tool longevity is prioritized. For example, it is a fine choice for:
- Cutting tool applications like end mills, inserts and saw blades. It is also helpful to machine complex profiles and shapes.
- It is also helpful in diverse machining applications, such as turning operations like facing, threading and boring.
- Inserts for turning, milling, as well as drilling activities.
- Also, Carbide has its utility in industry-specific applications, such as machining components like cylinder heads, cylinder blocks, and crankshafts.
- For the aerospace industry, carbide tools have their utility in machining landing gear, structural components, and engine parts.
Choosing between hot work tool steel and Carbide for specific applications can be tricky, especially when you have less experience in the manufacturing industry. This is where you can find some help from your local suppliers. The customer service of the most competent companies will always be ready for the help that you need.
