The result will be the same but at a lower efficiency . Galvanized sheet is practical
only because of the cathodic protection afforded the steel sheet by the thin zinc
layer . For many years , the maintenance of elevated steel water towers normally

The lower the amount of uncombined carbon or graphite the stronger the metal .
Gray iron has often been defined as steel plus graphite . Upon fracture , these
castings will exhibit a gray appearance ; hence , the name gray iron . The density

The most economical hardness for machinability is around 250 Bhn . As the
hardness increases , however , the machinability decreases ; thus , the lower -
tensile gray irons are much more machinable than those of higher - tensile .
There is a ...
