Tool Steel in Many Grades and Finishes. In-Stock and Special Orders Avaialble

Tool Steel refers to a variety of carbon and alloy steels that are produced to be made into tools. They are suitable because of their distinctive hardness, resistance to abrasion and deformation.  These products also hold a cutting edge at elevated temperatures which makes them perfect for knives and other cutting applications. As a result, tool steels are suited for their use in the shaping of other materials. available in a number of grades that are each suited to specific applications, such as punches, dies or cutting applications. If maximum service life and efficiency are to be obtained from tools and dies, it is most important that the proper grade of tool steel be selected for a given application.

Our tool steel materials are available in many alloys of rod, flat and square stock, including precision ground and oversize.

Decarb-Free Rounds
 

Cold Work
  • A2 – A medium-alloy, air-hardening tool steel. It is safer in hardening and has less distortion in heat-treating than the oil-hardening types. Its ability to hold a keen cutting edge, resistance to abrasion and wear, and deep-hardening properties, A2 exceeds the regular oil-hardening grades.
  • A6 – A low-alloy chromium-molybdenum air-hardening tool steel with a combination of toughness, strength,and wear resistance that makes it an excellent choice for general-purpose cold work tools and dies. Because of its low austenitizing temperature and air-hardening characteristics, A6 has excellent dimensional stability.
  • A8 – An air-hardening tool steel that is characterized by a combination of very good toughness, intermediate wear resistance, and excellent dimensional stability in heat treatment.  A8 tool steel is an excellent steel for punches and dies that operate in the 55 to 60 rockwell C hardness range.  The combination of toughness and wear resistance make A8 tool steel an excellent choice for application which require higher toughness than that of the high-carbon, high-chromium steels such as D2 and better wear resistance than that of shock resisting steels such as S7.
  • A10 – An air-hardening graphitic tool steel with outstanding resistance to metal-to-metal sliding wear and calling.  The steel contains a uniform dispersion of graphite particles, which impart excellent machinability and non-seizing characteristics.  The graphite particles make the steel self -lubricating in dry environments, and help to retain oil in lubricated environments.  A10 can be hardened over 60 Rockwell C from a relatively low hardening temperature, which minimizes size change and distortion during heat treatment.
