Tool Steel Forgings

Tool steels are engineered to offer exceptional hardness and durability, particularly when subjected to severe service conditions. Highly alloyed tool steels may contain alloying additions of up to 50%, with primary elements such as forged high-carbon steel, chromium, tungsten, and molybdenum, contributing to their remarkable properties.

Tool steel is renowned for its exceptional hardness, making it a preferred choice for applications that involve cutting other metals. This alloy’s distinct hardness surpasses that of most other materials, making it ideal for manufacturing tools, including forging dies, machine components, drills, blades, hammers, filers, and chisels. We maintain an extensive inventory of various tool steel grades to provide prompt service to our customers.
The open die forging process offers versatility, enabling the production of a wide range of final products. This flexibility allows us to create a diverse array of shapes and sizes, tailored to meet the precise requirements of your application. Whether you require forgings weighing just a few pounds or exceeding 150 tons, we can adapt the process to fulfill your specific needs.
