Zhihu netizens ask: How can metal materials balance high strength and high toughness?
There are five ways to strengthen metal materials,
The first type of strengthening involves adding carbon, but the higher the carbon C content, although the hardness increases, the toughness decreases accordingly.
The second type of alloy strengthening can improve hardenability and obtain certain carbide structures, thereby increasing strength and achieving certain special properties.
The third type of forging strength is to change the grain arrangement to improve strength, and many mechanical parts use forging strengthening technology.
The fourth method is fine grain strengthening, which is an ideal strengthening method that can both improve strength and ensure toughness, and is also a dream pursuit for material professionals. Powder high-speed steel is the best embodiment of this fine grain strengthening.
The fifth type of final heat treatment is quenching strengthening, which obtains the corresponding structure through heat treatment process to achieve the desired properties. Many high-strength metal materials need to be strengthened through this method. Heat treatment is an important part of strengthening tool steel, which determines the performance and effectiveness of tool steel.
These 5 reinforcement methods are not isolated, they are organically combined.

We, Yuhui, are a tool steel pre hardening factory that provides tool steel and heat treatment, focusing on anti cracking, high toughness, and non stick tool steel. We produce our own proprietary tool steel and tool steel that the three giants do not produce, but we do not produce standard steel for any particular steel plant.
