STEEL – SOME COMMON TYPES
www.skyshop.com.au6150 This chromium-vanadium alloy steel is similar to 4340. It has good harde na bil ity, good fatigue properties and excellent resistance to impact and abrasion. 8620 This is a “triple alloy” chromium-nickel-molybdenum steel. It is readily carburized. It may be heat treated to produce a strong, tough core and high case hardness.

A small annu-lar Gap exists between a high-strength steel core and the first layer of trapezoidal-shaped aluminum strands, which allows this to be achieved. The result is a conductor with a knee-point at the erection temperature. Above this, thermal expansion is that of steel (11.5 microstrain per Kelvin ...
