steels can be substituted for costly
alloy steels when flame-hardening
provides more efficient productivity
through increased wear resistance,
which translates into less down time.
Flame-hardening is a rapid,
economical method for selectively hardening specific
areas on the surface of a part. This process is
applied only to selected metal surfaces of carbon
and alloy steels, cast and ductile irons and some
stainless steels, followed by an appropriate quenching
The benefits of flame-hardening
are many. Increased wear resistance, less distortion,
reduced processing time and the ability to use low
to medium carbon steels all contribute to reduced

Our Methods of Production
flame-hardening is achieved by scanning the surface
of the metal, rapidly heating it and immediately
quenching it at a uniform speed. This speed generally
depends upon the desired depth of hardness.
is achieved when a part is surrounded by flame ejectors
and heated while being spun rapidly. When the part
reaches the proper temperature it is quenched through
submersion or spraying with an appropriate quenching
as the name implies, is when the other two techniques
are combined to provide
uniform heating and quenching of a rotating part.
Many applications can be found
for flame hardening. Various shapes, curved or straight,
varying lengths, widths, and thickness, can be flame
hardened in selective areas that are subject to
excessive wear. The flame hardening process can
be the best and most economical way to extend the
life of and provide a better wear surface for the
part. Here are a few examples of flame hardening
