machinery components, other machinery components, etc.
Why use forgings?
Forging offers uniformity of composition and structure. Forging
results in metallurgical recrystalisation and grain
refinement as a result of the thermal cycle and deformation
process. This strengthens the resulting steel product particularly
in terms of impact and shear strength.
Forged steel is generally stronger and more reliable than castings
and plate steel due to the fact that the grain flows of the steel
are altered, conforming to the shape of the part.
The advantages of forging include:
Generally tougher than alternatives
Will handle impact better than castings
The nature of forging excludes the occurrence of porosity,
shrinkage, cavities and cold pour issues.
The tight grain structure of forgings making it mechanically
strong. There is less need for expensive alloys to attain high
The tight grain structure offers great wear resistance without the
need to make products “superhard” We have found that, on a blank
HRC 38-42 forged grinder insert wear/wash is about the same as a
high alloy HRC 46-50 cast grinder insert. The difference being a
HRC 46-50 casting does not have the ductility to handle high impact
Types of Forging Processes
There are basically four methods (or processes) to make a forged
1. Impression Die Forging
2. Cold Forging
3. Open Die Forging
4. Seamless Rolled Ring Forging
Roll forging is a process where round or flat bar stock is reduced
in thickness and increased in length. Roll forging is performed
using two cylindrical or semi-cylindrical rolls, each containing
one or more shaped grooves. A heated bar is inserted into the rolls
and when it hits a spot the rolls rotate and the bar is
progressively shaped as it is rolled through the machine. The piece
is then transferred to the next set of grooves or turned around and
reinserted into the same grooves. This continues until the desired
shape and size is achieved. The advantage of this process is there
is no flash and it imparts a favorable grain structure into the
Examples of products produced using this method include axles,
tapered levers and leaf springs.
Seamless Rolled Ring Forging
Seamless rolled ring forging is typically performed by punching a
hole in a thick, round piece of metal (creating a donut shape), and
then rolling and squeezing (or in some cases, pounding) the donut
into a thin ring. Ring diameters can be anywhere from a few inches
to 30 feet.
Rings forged by the seamless ring rolling process can weigh < 1
lb up to 350,000 lbs., while O.D.’s range from just a few inches up
to 30-ft. in diameter. Performance-wise, there is no equal for
forged, circular-cross-section rings used in energy generation,
mining, aerospace, off-highway equipment and other critical
Seamless ring configurations can be flat (like a washer), or
feature higher vertical walls (approximating a hollow cylindrical
section). Heights of rolled rings range from less than an inch up
to more than 9 ft. Depending on the equipment utilized,
wall-thickness/height ratios of rings typically range from 1:16 up
to 16:1, although greater proportions have been achieved with
special processing. In fact, seamless tubes up to 48-in. diameter
and over 20-ft long are extruded on 20 to 30,000-ton forging
Even though basic shapes with rectangular cross-sections are the
norm, rings featuring complex, functional cross- sections can be
forged to meet virtually any design requirements. Aptly named,
these contoured rolled rings can be produced in thousands of
different shapes with contours on the inside and/or outside
diameters. A key advantage to contoured rings is a significant
reduction in machining operations. Not surprisingly,
custom-contoured rings can result in cost-saving part
consolidations. Compared to flat-faced seamless rolled rings,
maximum dimensions (face heights and O.D.’s) of contoured rolled
rings are somewhat lower, but are still very impressive in size.
High tangential strength and ductility make forged rings
well-suited for torque- and pressure-resistant components, such as
gears, engine bearings for aircraft, wheel bearings, couplings,
rotor spacers, sealed discs and cases, flanges, pressure vessels
and valve bodies. Materials include not only carbon and alloy
steels, but also non-ferrous alloys of aluminum, copper and
titanium, as well as nickel-base alloys.
