52100 Cr Steel
52100 is a high-carbon chromium alloy steel, which, because of its versatility, is used in a variety of mechanical applications. In the annealed condition this steel is comparatively easy to machine, yet very high hardness and abrasion resistance can be developed by heat treatment to make the steel particularly suitable for applications requiring extreme wear resistance. In addition, 52100 alloy steel can be heat treated to high levels of tensile strength and fatigue strength.
Tool Steels - Compared with tool steels in general, 52100 is less expensive and is much easier to handle. It is easier to form and machine than most tool steels yet can, after simple heat treatment, develop many of the proporties of tool steels.
Carburizing Grades - Compared with the carburizing grades of alloy steels, 52100 sacrifices some machinability but in return the user has a material with a much more simple and inexpensive heat treatment that minimizes distortion.
Three compositions of 52100 have been developed with a wide range of hardenabilities which are suitable for nearly any application requiring high hardness throughout medium to heavy sections. These analyses are as follows in order of increasing hardenability:

Steel Quality
The steel from which 52100 tubing is produced is made in electric furnaces using special refining techniques, which insure maximum cleanliness and freedom from objectionable microscopic slag type inclusions. This steel is made to conform to the stringent chemical and cleanliness requirements of ASTM, A295, and AMS 6440. The modified grades meet ASTM A485.Source: Sullivan Steel Services
