• When looking at hot rolled steel (also called hot
  rolled steel, or simply 'rolled steel') you must
  have a very clear picture of what it actually is
  before you can talk about its properties.
• If you are not a professional in the building and
  construction industry you will find it hard to
  differentiate one variety from another,
  especially in the arena of mild steel.
• So, what exactly is it? What properties does it
  possess? If you are looking for a quick and
  simple definition you can look up Wikipedia to
  see just that.

• Hot Rolled Annealed Stainless Steel Sheet - this
  type of steel is simply hot rolled steel that has
  been annealed.
• Annealed means under pressure, and when working
  with metals annealing creates small tears in the
  metal, which cause the neighboring metals to flow
  at much faster speeds.
• This creates a great characteristic when it comes
  to cutting and forming, because the smaller the
  tear the larger the cutting angle.
• Because of this characteristic and the fact that
  annealed steel has a slightly higher melting
  point than unlined steel, annealed sheet is
  excellent for use in abrasive applications such
  as flooring and fence post holes.

• It also has good thermal conductivity, which
  means that the sheet can be used to surround
  objects that need to be protected from high
  temperatures.
• Hot Rolled Annealed Stainless Steel Sheet - this
  type of steel is also called flat rolled steel,
  flat rolled, or simply rolled steel.
• Flat Rolled Annealed Steel is essentially the
  same as hot rolled annealed stainless steel
  sheet, but the process is reversed.
• This simply means that the cold work is done
  using hot rollers and annealing takes place using
  annealing ovens.

• This type of steel milling machine is often found
  in abrasive grinding equipment or as an
  ingredient in forming tools.
• There are two different ways in which the hot
  rolled surface can be produced.
• The first way is called criss-cross, and in this
  type of milling, one or both edges of the flat
  plate will be positioned parallel to each other.
• As the plate moves eastward into the annealed
  zone, the edges of the plate will bend slightly,
  and the plate will snap forward into position to
  form the desired angle.

6

• The second way in which the surface can be formed
  is by lapping.
• In this type of process, the plate is placed on a
  metal blank, and the blank is placed over the
  annealed steel plate, sliding it into the lapped
  position until it is completely annealed.
• Because the blank is heated in the annealing
  oven, it will conform to the shape of the plate
  as well, creating a tight, flat surface that will
  bend when pressed.
• Hot Rolled Annealed Steel is very valuable in
  abrasive milling because of its ability to cut
  hard materials with high compressive strength.

7

• The best of these types of plates for abrasive
  purposes can cut through many types of sheet
  materials and are also able to work with thinner
  sheets of metal.
• There are many uses for Hot Rolled Annealed Steel
  sheet products, including forming the base of
  hand tools, making tool handles, and forming
  pipes for use as seals.
• Hot Rolled Annealed Stainless Steel is ideal for
  forming pipes because the heat and pressure used
  in forming pipes and tubes is less than what
  would normally be required.
• This means that the annealed steel plate can be
  used as the pipe base and then welded together at
  the welding area, sealing the edges and
  preventing any leaks.

• Hot Rolled Annealed Stainless Steel has several
  benefits.
• It produces a stronger more wear resistant edge
  than cold rolled sheets.
• Abrasives are better handled when they have this
  edge so that they are more likely to form tight,
  strong joints.
• Hot Rolled Annealed Stainless Steel has the
  ability to resist corrosion from chemicals that
  are part of most construction.
• Most of the annealed steel products will be
  coated with zinc, copper or brass which provides
  additional protection against corrosion.

9

• Some of the things you should look for when
  shopping for Hot Rolled Annealed Stainless Steel
  are the gauge of the plate (the thickness of the
  material), the annealing time (how long it takes
  to reach the maximum temperature) and the heat
  treated finish.
• If the gauge of the plate is too thin, it will
  not have enough strength and will not perform
  well under stress. If the annealed time is too
  long, the product will be less effective and it
  could fail prematurely.

• If you need some advice on how to select your
  cold drawn Annealed Stainless steel, there are
  some tools you should consider.
• The first tool to consider is a thermometer
  because it will determine how the sheet is going
  to react.
• Another tool to consider is the tool's tolerance
  to thermal shock (this measures the tool's
  ability to withstand heat).
• The last tool to consider is how much you are
  willing to spend so you don't get taken advantage
  of.
