Aobo Steel 1.2436 Tool Steel – Durable High-Carbon Steel for Cold Work Applications

Aobo Steel supply 1.2436 tool steel for your project

For businesses seeking a dependable 1.2436 tool steel supplier, Aobo Steel offers a comprehensive range of solutions. If you are looking for high wear resistance in tool steel, then 1.2436 steel is an excellent choice. Specifically, 1.2436 steel is a chromium-rich, cold-work tool steel engineered for extreme durability. In fact, this high-carbon steel provides 3-4 times the wear resistance of typical low-alloy steel. Furthermore, it offers excellent hardness, toughness, and dimensional stability, making it ideal for demanding tooling applications.

Applications

1.2436 tool steel is widely used, especially to make cold work molds with large cross-sections and complex shapes. These molds are often subjected to significant impact forces and require high wear resistance. Applications include silicon steel punching dies, thread rolling dies, and drawing dies.

1.2436 is primarily suitable for medium-load stamping dies. It excels at punching stainless steel, copper, silicon, and aluminum.
1.2436 is commonly used for stainless steel and silicon steel sheet stamping dies under medium load. It is also effective for deep cup part stamping dies.
