(1)
Note. Where the wheel is claimed with no significant wheel
structure but merely in terms of the composition or material of

bonding, machining, or working combined with significant heat treatment
of railway wheels and axles to modify or maintain the internal physical

See the Class 148 definition to determine what constitutes significant
heat treatment. Without metal casting, fusion bonding, ma-chining, or
working, Class 148 will take any heat treatment to modify or maintain the
internal physical structure (i.e., microstructure) or chemical property of
metal.
