Repeated heat forging and heat cycling result in a very fine grain structure. Used by many custom makers, Swamp Rat knives use 52100 steel under the name SR101. Also referred to as 100 Cr 6/102 Cr6 as per ISO nomenclature and conforms to BS grade En31. SUJ2, Japanese equivalent to AISI 52100 steel. DIN 5401
Unsourced material may be challenged and removed. ( December 2015 ) ( Learn how and when to remove this message ) High speed steels are alloys that gain their properties from a variety of alloying metals added to carbon steel, typically including tungsten and molybdenum, or a combination of the two, often with other alloys as well.

A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The Japanese equivalent grade of this material is SUS304. Type 304L—same as the 304 grade but lower carbon content to increase weldability. Is slightly weaker than 304. Type 304LN—same as 304L, but also nitrogen is added to obtain a much higher yield and tensile strength than 304L.
is the equivalent dynamic load applied to the bearing p {\displaystyle p} is a constant: 3 for ball bearings, 4 for pure line contact and 3.33 for roller bearings Basic life or L 10 {\displaystyle L_{10}} is the life that 90% of bearings can be expected to reach or exceed. [ 13 ]
Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but also used as components in things like freewheel mechanisms. The balls themselves are commonly referred to as ball bearings. [1] This is an example of a synecdoche. The balls come in many different grades.
Material selection is often benefited by the use of material index or performance index relevant to the desired material properties. [2] For example, a thermal blanket must have poor thermal conductivity in order to minimize heat transfer for a given temperature difference. It is essential that a designer should have a thorough knowledge of the ...
Disposable equivalent of the Nikon EN-EL5 Li-ion rechargeable camera battery.
