Properties Of Alloy Steels






Category: ALLOYS AND THEIR EFFECT UPON STEEL

The following table shows the percentages of carbon, manganese,
nickel, chromium and vanadium in typical steel alloys for engineering
purposes. It also gives the elastic limit, tensile strength, elongation
and reduction of area of the various alloys, all being given the same
heat treatment with a drawing temperature of 1,100 deg.F. (600 deg.C.). The
specimens were one inch rounds machined after heat treatment.

Tungsten is not shown in the table because it is seldom used in
engineering construction steels and then usually in combination
with chromium. Tungsten is used principally for the magnets of
magnetos, to some extent in the manufacture of hacksaws, and for
special tool steels.
