Description of Plate
is the highest demand hot-roll steel plate in the world, as
engineers specify ASTM A36 for more structural steel
fabrications than any other type of plate. Among
the least expensive of the carbon steels. Very good welding properties along with 36ksi yield
strength. Considered a mild steel due to hardness.
gr. 50 plate is a high-strength, low-alloy plate, specified for
bridges, higher strength structural duties, and light pressure vessel requirements.
Recommended for riveted, bolted, or welded structures, such
as Gussets and
Bridge Plates, when intended for construction of
bridges. At 50ksi, a higher strength steel than A36. This alloy is often specified for various
structural applications whenever durability and hardness demands are slightly greater
than 36ksi ASTM A36. The additional strength may be purchased
for a relatively mild cost difference.
is a mild carbon steel denoted soley by a Chemistry

||A medium hard steel
often used for machine parts, for those machines that
manufacture parts from ceramic, plastic, steel, other metals, and other
composite materials. 1045 steel can be heat-treated and
hardened for increased durability. Annealing is recommended
following Flame Cutting in order to improve machineability and
to prevent stress cracks.
AISI 4140 is suitable
for heavy-duty service because of high hardenability, good
abrasive characteristics, and its impact resistance. Especially
suitable for tooling die and press plates. In the Rockwell range
of 28 - 32 (and higher through hardening.) Precision Grinding
has an onsite furnace for Annealing. We offer annealing services
to all customers purchasing 4140 burn-outs. Optionally, 4140 can
be purchased in the Pre-hardened (PH) condition with a higher
Rockwell hardness rating.
for manufacturing forging equipment and tooling. Known to be
tough and shock-resistant, 4340 is also capable of being
oil-hardened to increase toughness, strength, and durability.
Especially desirable when faced with severe impact, high-heat,
and extreme wear conditions. This steel must also be annealed
following flame cutting, then flame-hardened or quench and
tempered, if required.
||At 100 kilo-pounds per
square inch, this is a low-alloy, quenched and tempered steel.
Typically used to manufacture heavy equipment structures, such
as used in railcars, mining truck frames, boom crane extension
arms, and for mining applications such as with rock crushers,
sifting machines, and rock sorters.

Additional support for platens include
stainless 410ss and 420ss.
Steel Plate Standards
Structural steel shape properties, such as composition and strength are
regulated by agreement between parties who choose to accept
international standards. These international standards are created by
formally recognized regulating boards, often times comprised of
worldwide, volunteer members within respective industries. It is
customary for American made steel plate manufacturers to choose to have
their hot rolled plates recognized by several of these governing bodies,
such as ASTM International, ANSI, AISC, AISI, ASCE, ASME, and the AWS along
with their European Union standards counterparts.

While stocking large quantities of 96" x 240" in a
range of thicknesses up to 8" thick and larger, Precision Grinding,
Inc., located in Birmingham, Alabama USA manufactures steel plate
products and shapes for a variety of industries. We inventory full
sheets of plate that adhere to international standards specifications
regulated by AISI and ASTM. We also inventory small quantities of
structural steel angle, channel, I-beam, steel bar, and hollow
structural sections of tubing, including steel pipe and square tubing
fabricated weldments. When fabricating steel weldments, we adhere to
the standard practices as specified by ANSI, AISC, ASCE, the American
Society of Mechanical Engineers, and the
American Welding Society.
Cash Flow Improvement
Customers save a considerable amount of production time by taking
advantage of our One-Stop Shop approach. At the same
time you receive a very competitive price, you're also able to
improve your cash flow. When you have multiple vendors process
your steel orders, often times, you'll have to pay for parts of the
production cycle prior to receiving your goods. One of the greatest
benefits from using our one-stop-shop approach to cutting, grinding,
machining, and fabricating steel plate products in-house, under one
roof, is that you, the customer, will have the benefit of shipping
finished products to your customers prior to receiving your bill for the
