Rod and Plate Tool Steels
AISI SAE 0-1
This is an electric furnace melt oil hardening tool steel. A non-shrinking
general purpose tool steel, it has excellent abrasion resistance, toughness and machinability characteristics.
Analysis C .85-1.00, Mn 1.00-1.40, Si .50, Max, Cr.
.40-.60, W.40-.60 Max. AISI SAE A-2
Fine grain, electric furnace air hardening, 5% chrome tool steel. It is a superior quality steel which has excellent
wear and abrasion resistance properties.
Analysis C.95-1.25, Mn 1.00 Max, Cr 4.75-5.50, Mo .90-1.4, V.15-.50 AISI SAE W-1
W-1 water hardening is the most popular, versatile, and least expensive grade of tool steel. Its high carbon
content allows it to be used often without heat treatment for maintenance applications. It is a fine grained electric furnace melted commercial grade tool steel which is
supplied in the fully spheroidized 100% decarb free condition.
Analysis C .95-1.05, Mn .30-.40, Si .10-.25 AISI SAE S-7
S-7 Hi-shock tool steel is an excellent chock steel that can be and is often used in hot work applications where
the tool temperature does not exceed 1000 deg. F. This tool steel combines the qualities of high strength and good ductility for cold and medium hot work application.
Analysis
C .45-.55, Mn .20-.80, Si .20-1.00, Cr 3.0-3.5, V .20-.30, Mo 1.30-1.80
AISI SAE D-2
Fine quality, air hardened, electric furnace melt tool steel. The combination of superior abrasion resistance and
toughness found in D-2 results from its high carbon and high chromium composition. High chrome is an extraordinary tool steel that can be specified for the most demanding
applications. This is non-free machining tool steel.
Analysis C 1.40-1.60, Mn .60 Max, Cr 11.00-13.00, V 1.10 Max, Mo .70-1.20, Co 100 Max
