Tool Steel Powder Description:
a) High Speed Steels are high-performance special steels combining high toughness and high hardness levels, thanks to substantial proportions of elements like tungsten, molybdenum, vanadium and chromium which are able to form carbides. To improve hot hardness, cobalt may also be added.
b) High Speed Steels also have a high yield limit, high fatigue strength and high fracture strength and are suitable when abrasive/adhesive wear resistance is required.
c) Thanks to these properties, High Speed Steels are widely used in many applications: cutting tools (drills, end mills, taps, reamers etc.), saws, knives, cold- & hot-work tooling and wear parts.
d) High speed tool steel powders are used in tools for hot-forming of metals. Important mechanical properties for hot-working tools are:
1) hot hardness
2) tempering resistance
3) wear resistance
4) toughness

Tool Steel Powder Chemical Properties Available:
a) Chromium high speed steels
b) Cobalt high speed steels
c) Molybdenum high speed steels
d) Tungsten high speed steels
e) Vanadium high speed steels
a) A variety of carbon and alloysteels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive toughness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperatures (red-hardness). Tool steel is also useful for making objects intended to resist tampering (such as locks and hinges) so they cannot be defeated with normal tools.
b) 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 minimise 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.
c) 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.
