Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
Heavier machine tools with higher rigidity were needed to use the new steel to its full advantage, prompting redesigns and replacement of installed plant machinery. The patent was contested and eventually nullified. [7] The first alloy that was formally classified as high-speed steel is known by the AISI designation T1, which was introduced in ...
Physical properties are those of the individual material groups, such as the modulus of elasticity, thermal conductivity, thermal expansion, and work hardening. [3] Other important factors are operating conditions, cutting tool material and geometry, and the parameters of the specific machining process being performed. [3]
Cutting tool materials must be harder than the material of the workpiece, even at high temperatures during the process. The following properties are required for cutting tool materials: [1] hardness, hot hardness and pressure resistance; bending strength and toughness; inner bonding strength; wear resistance. oxidation resistance
S1, a medium-carbon shock-resisting steel tool steel which combines moderate hardness with good impact toughness. Carbon content 0.40 - 0.55%. [11] W1, a water hardening tool steel. High carbon content. W2, a tool steel that holds its edge quite well but is not very tough.
SVCM steel is a kind of shock-resisting steel. [5] SVCM steel is an alloy of carbon, silicon, chromium, magnesium, nickel, molybdenum and lead. [6] SVCM+ in addition is quenched and tempered achieving a high hardness (HRC 59). [6] SCVM+ has better torsional properties than chromium-vanadium steel (Cr-V). [7]

Caldie is a chromium-molybdenum-vanadium alloyed tool steel manufactured by Uddeholms AB. It is intended for cold work processes, such as blanking and piercing , applied to difficult materials such as advanced high strength steel , where compressive strength and chipping and cracking resistance are important.
