    AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series. HSS grade steel M2
    is a medium alloyed high speed steel which has good machinability. The
    H-SS M2 chemical composition gives a good combination of well-balanced
    toughness, wear resistance and red hardness properties. Widely used for
    cutting tools such as twist drills, taps, milling cutters, saws, knives
    etc. Also commonly used in cold work punches and dies and cutting
    applications involving high speed and light cuts.

    Grade M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel grade T1 in most applications because of its superior properties and relative economy.

    4. Forging of AISI M2 High Speed Steel

    Pre
    heat M2 HSS steel slowly and uniformly to 850-900°C. The heat should
    then be increased more quickly to the forging temperature of
    1050-1150°C. If during the forging
    the temperature of the M2 high speed tool steel material drops below
    880-900°C, re-heating will be necessary. Cool the M2 steel component
    very slowly after forging.

    5. Heat Treatment of M2 Steel HSS

    • Anneal

    Heat
    to 1600° F, soak thoroughly at heat. Furnace cool 25° F per hour to
    900° F, air cool to room temperature. Approximate annealed hardness 241
    Maximum Brinell.

    Stress Relief of Unhardened Material: Heat slowly
    to 1200 to 1250° F. Soak for two hours per inch of thickness at heat.
    Slow cool (furnace cool if possible) to room temperature.

    • Hardening

    Preheat: Heat slowly to 1550° F, soak thoroughly, heat to 1850° F, soak thoroughly.

    • Harden

    Soak
    time in the furnace varies from a few minutes to a 15 minutes,
    depending tool size, heat capacity of the furnace, and the size of the
    charge. – Heat to 2150 to 2200° F for max. toughness and minimum
    distortion. – Heat to 2250 to 2275° F for max. hardness and abrasion
    resistance.

    • Quench

    For full
    hardness, oil quench to 150-200° F. Air quench to 150° F. When quenching
    in hot salt maintain the quench just above the Ms temperature. After
    equalizing withdraw parts from the hot salt and air cooled to 150° F.

    • Temper

    Double
    temper is mandatory, three tempers are sometimes preferred. Soak for 2
    hours per inch of thickness. Air cool to room temperature between
    tempers. The best tempering range for hardness, strength and toughness
    is 1000 to 1050° F.

    Temper° F Rockwell “C” Temper° F Rockwell “C”
    As-quenched 64 900 64
    400 63 1000 65.5
    500 62.5 1050 63.5
    600 62.5 1100 61.5
    700 62.5 1150 60
    800 63.5 1200 53

    6. Machinability of AISI M2 Tool Steel H-SS

    Shaping
    of HSS M2 tool steels can be carried out using grinding methods.
    However, they have poor grinding capability and hence they are regarded
    as “medium” machinability tool steel under annealed conditions. The
    machinability of these tool steels M2 is only 50% of that of the easily
    machinable W group or water hardening tool steels.

    7. M2 Tool Steel Applications

    The main use of high-speed steels continues to be in the manufacture of various cutting tools.

    Typical
    applications for M2 high speed steel are twist drills, reamers,
    broaching tools, taps, milling tools, metal saws. M2 is suitable for
    cold forming tools such as extrusion rams and dies, also widely used in
    all kinds of cutting tools, knife and punches and die applications,
    plastic moulds with elevated wear resistance and screws.

    ABSTRACT

    Electrical power is, and will increasingly become, the desired form of energy for its convenience, safety, flexibility and applicability. Even future transportation embraces electric cars, trains, and chemical fuel production (jet fuel, hydrogen, etc.) based upon an abundant electrical supply. Although existing energy sources can and should be expanded where practical, no one source has shown to be practical to rapidly fulfill the world’s energy requirements effectively. Presently there is an existing source of energy ideally suited to electrical energy production that is not being exploited anywhere in the world today, although its existence and practicality has been know since the earliest days of nuclear science. Thorium is the third source of fission energy and the LFTR is the idealized mechanism to turn this resource into electrical energy. Enough safe, clean energy, globally sustainable for 1000′s of years at US standards.

    This talk is aimed at explaining this thorium energy resource from fundamental physics to today’s practical applications. The presentation is sufficient for the non-scientist to grasp the whole subject, but will be intriguing to even classically trained nuclear engineers. By providing the historical context in which the technology was discovered and later developed into a power reactor, the story of thorium’s disappearance as an energy source is revealed. But times have changed, and today, thorium energy can be safely exploited in a completely new form of nuclear reactor.

    The LFTR is unique, having a hot liquid core thus eliminating fuel fabrication costs and the need for a large reactor. It cannot have a nuclear meltdown and is so safe that typical control rods are not required at all. This design topples all the conventional arguments against conventional energy sources in such areas as:

    * Waste Production
    * Safety
    * Proliferation
    * Capital Costs and Location
    * Environmental Impact
    * Social Acceptance
    * Flexibility
    * Grid Infrastructure
    * Efficiency

    Should America take this step toward a New Era in Nuclear Energy Production? Hear the case for “The Electricity Rock” and then decide.
