Tool Steel Rectangle Bar

Tool Steel Rectangle Stock embodies toughness and durability, crafted from high carbon chrome steels infused with molybdenum, cobalt, vanadium, and other elements. Annealed for machinability, subsequent heat treatment enhances toughness and strength, making it ideal for crafting cutting tools, dies, and more. With densely-packed metal lattices and carbide-forming elements like Molybdenum, Chromium, Vanadium, and Tungsten, it offers exceptional wear resistance and hardness. Tool steel is versatile and resilient and great for cutting, machining, stamping, or forging applications.

 

We carry Tool Steel Rectangle/Flat Bar in: A2 | D2 | H13 | O1 | S7 and W1.
