Tool Steel

Tool Steels are carbon and alloy steels known for their exceptional hardness and resistance to abrasion, which is why they are typically used to make into tools. They are used often for cutting, pressing and coining other metals and materials. Tool Steels are also used in production of injection molds. This material is prepared over-sized to finish for the customer, typically (+.020/.040”) on the thickness, unless specified otherwise.

 

Tool Steel Grades:

A2A6 – D2H13 – O1  – L6 – S1 – S5 – S7

 

A2 Tool Steel Rounds / Flats

A2 tool steel is an air-hardening, medium-alloy, cold-work tool steel that has 5% chromium. A2 is characterized by good machinability, good toughness, excellent dimensional stability in heat treatment, and high wear resistance. A2 tool steel is composed of a high carbon content which allows it to be deep hardened in order to minimize distortion. A2 is an upgrade over O1 oil-hardening steel when higher toughness, higher wear resistance, and lower distortion are required. The typical applications of A2 tool steel are punches and dies, dowel pins, precision tools, gauges, shear blades, slitters, industrial knives, and more.

 

A6 Tool Steel Rounds / Flats

A6 is an air-hardening, non-deforming, decarb free tool steel that is characterized by deep hardening, low distortion, moderate toughness and wear resistance. The chemical composition of A6 steel has a higher manganese, lower chromium and carbon content than A2 steel.  An advantage of A6 steel is its lower hardening temperature range of 1500 – 1600 °F, that is typically only found in oil-hardening steel grades.

 

D2 Tool Steel Rounds / Flats

D2 tool steel is a high carbon, high chromium, air-hardening, cold work tool steel that is characterized by excellent wear and abrasion resistance properties. The high chromium content of D2 gives it mild corrosion resistance properties in the hardened condition. While D2 is very wear and abrasion resistant it is not as tough as alloyed steels and is very sensitive to heat treatment. D2 is used for the parts that require absolute highest wear/abrasion resistance such as a long run productions parts and is an upgrade over A2. The typical applications for D2 tool steel are Rolls, Punches, Blanking Dies, Forming Dies, Trimming Dies, Shear Knives, Planer Blades, Knife Blades, and more. We sell D2 tool steel in both rounds and flats.

 

H13 Tool Steel Rounds / Flats

H13 tool steel is a chromium-molybdenum hot-work steel that is characterized by high hardenability, excellent wear resistance, and excellent hot hardness. H13 is known for its good thermal shock resistance which reduces thermal fatigue cracking from repeated heating and cooling cycles. The combination of excellent hot hardness and good thermal shock resistance makes H13 an excellent choice for hot work applications. The typical applications of H13 tool steel are forging die inserts, hot press dies, hot shear blades, stamping dies, hot work punches, plastic molds, aluminum castings, and more.

 

O1 Tool Steel Rounds / Flats (A.K.A. 01 Tool Steel)

O1 is an all-around general purpose oil-hardening tool steel that is characterized by reliable hardening, very good machinability, good wear resistance, and sufficient toughness for a wide variety of tool and die applications. O1 is one of the most widely used grades of tool steel because of its unique balance of toughness and moderate price. We sell O1 Tool Steel Rounds and Flats.

 

L6 Tool Steel Rounds / Flats

L6 is a low alloy, non-deforming, oil-hardening tool steel that is characterized by its very good toughness, high strength, and extremely good machinability. The relatively high nickel content in L6 results in greater impact/shock resistance and toughness as compared to other oil-hardening steel grades. The typical applications of L6 tool steel are springs, bearings, punches and dies, rollers, chuck parts, cold forming tools, spindles, shear blades, and more.

 

S1 Tool Steel Rounds

S1 is a chromium-tungsten, shock-resisting tool steel that is characterized by high impact resistance, high hardenability, moderate hardness, good toughness and wear resistance. S1 is a low carbon tool steel that is excellent for both hot-work and cold-work applications.

 

S5 Tool Steel Rounds

S5 is a Silicon-Manganese-Moly-Vanadium shock-resisting tool steel that is known for having the highest impact toughness of the “S” type steels. S5 tool steel can be hardened to 62 Rockwell C and provides high toughness. S5 is an excellent choice when applications require a higher strength and toughness than S7 tool steel.

 

S7 Tool Steel Rounds / Flats

S7 tool steel is a low carbon, shock resistant, air-hardening or oil-hardening steel that is characterized by very high impact toughness, medium wear resistance, and high hardness. S7 is a specialty tool steel that is designed to resist high and low temperature shocks as well as impacts. S7 tool steel can be used both hot-work and cold-work applications. This allows S7 to be used for an extremely wide variety of tool and die applications. The very high impact toughness makes S7 a popular choice for knife steel.
