John Prosock Machine, Inc., a CNC
machine shop in PA, has years of experience in
steel and stainless steel precision CNC machining.
Generally, steel is malleable, strong, and versatile
enough to be used in various end product or system
applications; however, different grades demonstrate
different machinability characteristics. John
Prosock Machine can recommend the best steel based
on your job requirements. There are essentially
two types of steel, carbon and alloy. Listed below
are some examples of the carbon and alloy steels
we can machine and the possible uses of each.
Stainless
Steel
Of the 150 plus grades of stainless steel that
exist, 15 are most common. This alloy can be machined
into sheet, plate, bar, wire, or tubing form for
equipment ranging from cookware, to hardware,
to surgical devices, to general appliances, and
to industrial and architectural end part applications.
Stainless steel is suitable in many natural and
man-made environments due to its high resistance
to oxidation and corrosion. Relative low cost,
little maintenance, and luster make stainless
steel ideal in many commercial applications as
well.
316
Stainless Steel
316 Stainless is similar to 304 stainless steel,
but includes molybdenum and an increased level
of nickel. The addition of molybdenum makes 316
Stainless resistant to pitting and crevice corrosion.
Even at high temperatures, 316 Stainless maintains
its strength and creep, or deformation, resistance.
Mechanical and corrosion properties withstand
even under sub-zero temperatures. 316 Stainless
has applications in many industry sectors from
tanks and storages vessels, to equipment for chemicals,
food, pharmaceutical, and petroleum.
Cold
Rolled Steel
Cold rolled steel is processed while in a cold
state. Hot chemically sanitized coil is rolled
and then cooled. Cold rolling reduces the thickness
of the steel and alters the mechanical properties.
When this type of steel comes in contact with
water in the air rust often forms. To prevent
damage, cold rolled steel is covered with a thin
layer of oil. Improved finish characteristics
and close dimensions tolerances make cold rolled
steel perfect for product where critical requirements,
high quality, and consistency are important.
1018
Steel
1018 Steel is one of the most common grades of
steel currently available. 1018 Steel is valued
because it can be easily formed, machined, welded,
and fabricated. Its chips are continuous and rigid
which result in a fine finish. 1018 Steel is often
utilized in high volume screw machine part applications
commonly found in shafts, spindles, pins, rods,
and more.
12L14
Steel
12L14 Steel is resulfurized and rephosphorized
screw machine stock with the addition of lead
content. This type of steel has good ductility
and finish characteristics, which make it suitable
for parts involving bending, crimping, or riveting
such as in bushings, inserts, couplings, and hose
fittings. 12L14 Steel is a form of carbon steel,
a combination of carbon and iron, and has become
an ideal precision machining material.
