IBC (Tianjin) Industrial Co., Ltd produce & export high speed tool steel to all over the world for decades years. High Speed Tool Steels and their requirements are defined by The American Society for Testing and Materials in Specification A600-79. Including many kinds of products, such as T1. T4, T5 high speed tool steel, and M2, M35, and M42 high speed tool steel and so on.


High-speed tool steels are so named primarily because of their ability to machine materials at high cutting speeds. They are complex iron-base alloys of carbon, chromium, vanadium, molybdenum, or tungsten, or combinations thereof, and in some cases substantial amounts of cobalt. The carbon and alloy contents are balanced at levels to give high attainable hardening response, high wear resistance, high resistance to the softening effect of heat, and good toughness for effective use in industrial cutting operations.

Surface Treatments
High speed steel tools often receive a bright or black oxide finish for use with non-ferrous or ferrous metals, respectively. Other coatings and treatments are possible, as well. Nitriding diffuses nitrogen into the surface of the steel during heat treatment, producing a case-hardened surface that shows higher wear resistance at the expense of notch hardness.
Another common treatment is titanium nitride (TiN) via physical vapor deposition, which enhances edge retention significantly. This, combined with a lower coefficient of friction, means an extended lifespan and improved machining, though TiN-coated tools react adversely with titanium or nickel alloys.
Factors in Selecting High Speed Tool Steels
No one composition of high-speed tool steel can meet all cutting tool requirements. The general-purpose molybdenum steels such as M l, M2, and M7 and tungsten steel T I more commonly used than other high-speed tool steels. They have the highest toughness and good cutting ability, but they possess the lowest hot hardness and wear resistance of all the high-speed tool
steels. The addition of vanadium offers the advantage of greater wear resistance and hot hardness, and steels with intermediate vanadium contents suited for fine and roughing cuts on both hard and soft materials. The 5% V steel (TI5) especially suited for cutting hard metals and alloys or high-strength steels. And particularly suitable for the machining of aluminum, stainless steels, austenitic alloys, and refractory metals. Wrought high-vanadium high-speed tool steels are more difficult to grind than their P/M product counterparts. The addition of cobalt in various amounts allows still higher hot hardness, the degree of hot hardness being proportional to the cobalt content. Although cobalt steels more brittle than the noncobalt types. They give better performance on hard, scaly materials that machined with deep cuts at high speeds.
High-speed tool steels have continued to be of importance in industrial commerce for 70 to 80 years despite the inroads made by competitive cutting tool materials such as cast cobalt alloys, cemented carbides, ceramics, and cermets. The superior toughness of high speed tool steels guarantees its niche in the
cutting tool materials marketplace.
Application of High Speed Tool Steel
Tool Steel High Speed is a cutting tool material used in drilling, milling, turning, threading, boring, broaching, gear cutting and many other machining operations. High Speed Steel used for form tools, slitter knives, guillotine knives, parting tools and many other types of cutting tools. It cutting tools used in all phases of production and widely used in both machine tools and in portable machine tools.
Broadly, high speed steel excels in hardness and abrasion resistance, with different grades trading for toughness, hot hardness or reduced brittleness. As a result, these alloys see the most use in industrial cutting tools—tool bits, milling cutters, saw blades, drills, taps, broaches and more.

Tools made of high speed steel frequently keep a sharp edge for longer than other carbon steels, and the variety of grades and surface treatments available provide options for specialized applications. These products see use anywhere from woodworking to machining high-grade alloys.
Though not traditionally considered to be cutting tools, punches, dies and other components in progressive stamping can also be made from high speed steel. Additionally, the properties of high speed steels, particularly hardness and wear resistance, are desirable for hand tools such as chisels, files, blades for hand planes and kitchen and pocket knives.
