Tool steels are hardened for cutting, forming and shaping other materials. E STEEL SDN BHD supplies cold work, hot work, shock-resisting and high-speed grades as plate and bar, cut to size with no minimum order quantity.
Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperatures (red-hardness). Tool steel is generally used in a heat-treated state.
With a carbon content between 0.7% and 1.4%, tool steels are manufactured under carefully controlled conditions to produce the required quality. The manganese content is often kept low to minimize the possibility of cracking during water quenching. However, proper heat treating of these steels is important for adequate performance, and there are many suppliers who provide tooling blanks intended for oil quenching.
Tool steels are made to a number of grades for different applications. Choice of grade depends on, among other things, whether a keen cutting edge is necessary, as in stamping dies, or whether the tool has to withstand impact loading and service conditions encountered with such hand tools as axes, pickaxes, and quarrying implements. In general, the edge temperature under expected use is an important determinant of both composition and required heat treatment. The higher carbon grades are typically used for such applications as stamping dies, metal cutting tools, etc.
Tool steels are also used for special applications like injection molding because the resistance to abrasion is an important criterion for a mold that will be used to produce hundreds of thousands of parts.
W-grade tool steel gets its name from its defining property of having to be water quenched. W-grade steel is essentially high carbon plain-carbon steel. This type of tool steel is the most commonly used tool steel because of its low cost compared to other tool steels. They work well for small parts and applications where high temperatures are not encountered; above 150 °C (302 °F) it begins to soften to a noticeable degree. Hardenability is low so W-grade tool steels must be quenched in water. These steels can attain high hardness (above HRC 60) and are rather brittle compared to other tool steels.
The toughness of W-grade tool steels are increased by alloying with manganese, silicon and molybdenum. Up to 0.20% of vanadium is used to retain fine grain sizes during heat treating.
Air-hardening grades
The first air hardening grade tool steel:
A2 is the most common air hardening grade currently used.
Grade-O refers to oil hardening tool steels, while grade-A refers to air hardening tool steels. These tool steels are used on larger parts or parts that require minimal distortion during hardening. The use of oil quenching and air hardening helps reducing distortion as opposed to higher stress caused by quicker water quenching. More alloying elements are used in these steels, as compared to water-hardening grades. These alloys increase the steels’ hardenability, and thus require a less severe quenching process. These steels are also less likely to crack and are often used to make knife blades.
D-grade tool steels contain between 10% and 18% chromium. These steels retain their hardness up to a temperature of 425 °C (797 °F). Common applications for these grade of tool steel is forging dies, die-casting die blocks, and drawing dies. Due to high chromium content, certain D-grade tool steel grades are often considered stainless or semi-stainless tool steels.
Composition
Here are composition for some of the most common cold-working tool steels, quantities of minor ingredients may vary slightly with manufacturer:
O-1 steel contains 0.90% carbon 1.0%–1.4% manganese, 0.50% chromium, 0.50% nickel, and 0.50% tungsten. It is a very good cold work steel and also makes very good knives. It can be hardened to about 57-61 HRC.
A-2 steel contains 1.0% carbon, 5.0% chromium, and 1.0% molybdenum.
D-2 steel contains 1.5% carbon and 11.0 – 13.0% chromium; additionally it is composed of 0.45% manganese, 0.030% max phosphorus, 0.030% max sulfur, 1.0% vanadium, 0.7% molybdenum, and 0.30% silicon. D2 is very wear resistant but not as tough as lower alloyed steels. It is widely used for shear blades, planer blades and industrial cutting tools, sometimes used for knives.
S-grade tool steel are designed to resist shock at both low and high temperatures. A low carbon content is required for the necessary toughness (approximately 0.5% carbon). Carbide-forming alloys provide the necessary abrasion resistance, hardenability, and hot-working characteristics. This family of steels displays very high impact toughness and relatively low abrasion resistance, it can attain relatively high hardness (HRC 58/60). This type of steel is used in applications such as jackhammer bits.
T-grade and M-grade tool steels are used for cutting tools where strength and hardness must be retained at temperatures up to or exceeding 760 °C (1,400 °F). M-grade tool steels were developed to reduce the amount of tungsten and chromium required.
T1 (also known as 18-4-1) is a common T-grade alloy. Its composition is 0.7% carbon, 18% tungsten, 4% chromium, and 1% vanadium. M2 is a common M-grade alloy.
H-grade tool steels were developed for strength and hardness during prolonged exposure to elevated temperatures. All of these tool steels use a substantial amount of carbide forming alloys. H1 to H19 are based on a chromium content of 5%; H20 to H39 are based on a tungsten content of 9%-18% and a chromium content of 3%–4%; H40 to H59 are molybdenum based.
A2 Tool Steel, 1.2363, SKD12, XW10
AISI A2 tool steel is one of ‘A’ group cold works steel in ASTM A681 standard. A2 Tool Steel is a versatile, air hardening chromium alloy tool steel that replaces O1 tool steel when safer hardening, less distortion and increased wear resistance are required. AISI type A2 steel is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.
AISI Steel A2 is heat treatable and will offer a hardness in the range 57-62 HRC. ASTM grade A2 steel delivers good toughness with medium wear resistance and is relatively easy to machine. Tool Steels A2 are used in many applications which require good wear resistance as well as good toughness.

SKD12 tool steels are heat treated at temperatures ranging from 177°C (350°F) for Rockwell C 62 to 538°C (1000°F) for Rockwell C 56 and then tempered.
A2 tool steels are annealed at 857°C (1575°F) and then cooled slowly in the furnace at a rate of 4°C (40°F) per hour or less.
1.2363 tool steels are heated slowly to 788°C (1450°F) and this is followed by increasing the temperature to 954°C (1750°F). A2 tool steels are further held at 954°C (1750°F) for 30 to 45 minutes and finally removed from the furnace and cooled.
2363 tool steel takes a place between AISI O1 and AISI D2, offering an excellent combination of good wear resistance and toughness. It may be regarded, therefore, as a“universal” cold work steel.
For cutting operations the good toughness of AISI A2 steel gives excellent resistance to chipping of the cutting edge. In many cases tools made from this A2 steel have given better tooling economy than high-carbon, high-chromium steels of the D3/ W.-Nr. 2080 type. AISI steel A2 has much better machining and grinding properties
Typical Applications for AISI/ASTM A2 steels materials: Blanking dies, block and ring gauges, coining, cold forming, cold trimming and forming dies, cold shears, rolls, knurls and knurling tools, machine parts, mandrels, punches and punch plates, reamers, shear and slitter blades, stamping dies and threading tapes.

Preheating: To minimize distortion and stresses in large or complex tools use a double preheat. Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1100°F (593°C) equalize, then heat to 1450-1550°F (788-843°C). For normal tools, use only the second temperature range as a single preheating treatment.
Austenitizing (High Heat): Heat rapidly from the preheat. For Cutting Tools: Furnace: 2200-2250°F (1204-1232°C) Salt: 2175-2225°F (1191-1218°C) To maximize toughness, use the lowest temperature. To maximize hot hardness, use the highest temperature. For punches, dies, and tools that require maximum toughness without hot hardness: Furnace: 2075-2175°F (1175-1191°C) Salt: 2050-2150°F (1121-1177°C)
Quenching: Pressurized gas, warm oil, or salt. For pressurized gas, a rapid quench rate to below 1000°F (538°C) is critical to obtain the desired properties. For oil, quench until black, about 900°F (482°C), then cool in still air to 150 -125°F (66-51°C). For salt maintained at 1000-1100°F (538-593°C), equalize, then cool in still air to 150 -125°F (66-51°C).
Tempering: Temper immediately after quenching. Typical tempering range is 1025-1050°F (552-566°C). Hold at temperature for 2 hours, then air cool to ambient temperature. Double tempering is required. For large cross sections, and especially for blanks from which tools will be cut by wire EDM, triple tempering is strongly recommended.
