What are Omni's Stainless Steel Product
product classifications help describe material options and design features
generally offered together for use in various washdown,
corrosive, and food processing applications and environments. These
specifications may be modified and combined to suit individual customer
requirements as needed.
stainless steel material handling components are used for sanitary and food
processing applications. These products are manufactured in accordance with
American Meat Institute (AMI) and USDA sanitary design criteria and are
intended to be easily cleanable, accessible and inspectable.
Steel mills and
warehouses perform various operations such as hot rolling, cold rolling, annealing
and pickling, during the production of stainless steel basic mill forms
– plate, sheet, strip, bar, tubing and wire. These operations are
intended to bring the steel product to a specific shape, dimension, and
metallurgical condition. The resulting finish is generally referred to as a
mill finish. It may also be described as a rolled or unpolished finish. The
most common stainless steel sheet finish produced is described as a No. 2B
mill finish. It is a bright, smooth, semi-reflective, and non-directional
finish. No. 2B sheet has a surface roughness with a maximum Ra of 32
micro-inches, which is equivalent to (or better than) a 150 grit finish, and
is considered equal to (or more smooth than) a No. 4 polished finish.
It should be
noted that different grades and thicknesses of stainless steel can result in
a variation of visual appearance for the same finishing operation. It should
also be noted that areas where welds and tool marks were cleaned-up cannot be
blended or repaired to recreate an original mill finish appearance. These
reworked areas will remain apparent unless additional surface finishing
operations are performed.
mechanical operations which include grinding, polishing and buffing are
intended primarily to change the appearance and condition of stainless steel
metal surfaces. The finish resulting from these operations is referred to as
a polished finish. It may also be described as a brushed or satin finish. The
most common stainless steel sheet cosmetic polished finish is described as a
No. 4 finish. It is a bright, uni-directional
finish with a visible "grain" which prevents mirror reflection. It
is obtained by finishing with a 120-150 mesh abrasive, following initial
grinding with coarser abrasives, and has a surface roughness with a maximum
Ra of 32 micro-inches. A No. 4 polished finish is generally only produced on
one side of the sheet while the reverse side is generally either a No. 2B or
No. 3 finish.
It should be
noted that areas where welds and tool marks were cleaned-up can be blended or
repaired by using the same or similar polishing methods that were used to
create the original finish.
surface treatments performed to change the appearance of stainless steel include
blasting with abrasive mediums. Glass bead blasting produces a bright uniform
matte or frosted finish with low reflectivity and no directionality. It
reduces glare from shiny stainless steel while still retaining a smooth feel.
It has a surface roughness with a maximum Ra of 125 micro-inches. Sand
blasting produces a much duller and less smooth finish than glass bead
