  2. High-speed steel - Wikipedia

    en.wikipedia.org/wiki/High-speed_steel

    M42 is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. [14] It is widely used in metal manufacturing industries because of its superior red-hardness as compared to more conventional high-speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time ...

  3. Motorcycle wheel - Wikipedia

    en.wikipedia.org/wiki/Motorcycle_wheel

    A 1977 Harley-Davidson XLCR with seven-spoke alloy wheels manufactured by Morris [8]. High-performance motorcycles began to use cast alloy wheels (usually aluminum but sometimes magnesium) as early as the Münch Mammoth, with its single cast-elektron [9] rear wheel which was shown at the Intermot motorcycle show at Cologne in late 1966. [10]

    en.wikipedia.org/wiki/Spark_testing

    Manganese steel has medium length sparks that fork twice before ending. [5] High-speed steel High-speed steel has a faint red spark that sparks at the tip. [5] 300-series stainless steel These sparks are not so dense as the carbon steel sparks, do not fork, and are orange to straw in color. [2] 310-series stainless steel

  6. Motorcycle testing and measurement - Wikipedia

    en.wikipedia.org/wiki/Motorcycle_testing_and...

    With power typically being the product of force and speed, a motorcycle's power and torque ratings will be highly indicative of its performance. Reported numbers for power and torque may however vary from one source to another due to inconsistencies in how testing equipment is calibrated, the method of using that equipment, the conditions during the test, and particularly the location that ...

    Elastic properties describe the reversible deformation (elastic response) of a material to an applied stress.They are a subset of the material properties that provide a quantitative description of the characteristics of a material, like its strength.

  9. Maraging steel - Wikipedia

    en.wikipedia.org/wiki/Maraging_steel

    Maraging blades are superior for foil and épée because crack propagation in maraging steel is 10 times slower than in carbon steel, resulting in less frequent breaking of the blade and fewer injuries. [i] [19] Stainless maraging steel is used in bicycle frames (e.g. Reynolds 953 introduced in 2013) [20] and golf club heads. [21]
