T11 Carbon Tool Steel
T11 is a kind of carbon tool steel, also referred to as alloy steel. This kind of tool steel belongs to the high-carbon, high-chromium type of tool steel. It has good resistance to abrasion and wear, excellent toughness and strength, and can be hardened to a high level through proper heat treatment and quenching processes. It also provides good resistance to oxidation.
The main components of T11 are Carbon (ranging from 0.7% to 1.1%), Silicon (up to 0.4%) and Manganese (0.4%-0.8%). Chromium content ranges from 0.4% to 0.7%. Trace amounts of other elements such as Molybdenum, Vanadium and Nickel may also be present.
T11 is usually supplied in the annealed condition. This temper can reach up to Rc 28 hardness. It is used in applications requiring a harder surface, such as dies, cutting tools, and highly stressed parts, where higher hardness and impacts are required.
Thanks to its high carbon content and hardening properties, T11 can be used in many high-strength pieces such as gears, shafts, rams and rods. The wear-resistant property of this grade is well suited for fabrication operations like punching, shearing and drawing. Due to its high resistance to abrasion and steel, it is suitable for the manufacture of injection moulds for the production of tough plastic articles.
T11 tool steel can be machined at relatively low speeds, but it needs to be cut at a slower rate than other alloy steels. Tooling and cutting edges should be kept sharp during operation and any resultant curling must be minimized. When welding this steel, it is important to ensure that the weld metal is pre-heated, as high thermal shock can lead to cracking and brittleness.
T11 is also known as 1.1216, 55WCrV8, and SKS31. It is a popular grade of tool steel and is widely used in various industries, including automotive, engineering and construction, and medical.
Despite its benefits, the high cost of this tool steel and its fragility when heated make it an unpopular choice in some applications. T11 can be replaced with other tool steels like T12, which offer similar benefits but at a lower cost and with increased resistance to shock and wear.
