Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless
steel, available in a wider range of products, forms and finishes than any other. It has excellent
forming and welding characteristics.
Chemical Formula 316 grade
Fe, <0.03% C, 16-18.5% Cr, 10-14% Ni, 2-3% Mo, <2% Mn, <1% Si, <0.045% P, <0.03% S
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the
austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than
Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
It has excellent forming and welding characteristics.

Cutting
Hydr. & Laser
Process
Industrial Laser Cutting of Steel with Cutting Instructions Programmed Through the CNC Interface.
Generation of the laser beam involves stimulating a lasing material by electrical discharges or lamps
within a closed container. As the lasing material is stimulated, the beam is reflected internally by means
of a partial mirror, until it achieves sufficient energy to escape as a stream of monochromatic coherent
light. Mirrors or fiber optics are typically used to direct the coherent light to a lens, which focuses the
light at the work zone. The narrowest part of the focused beam is generally less than 0.0125 in
(0.3175 mm). in diameter. Depending upon material thickness, kerf widths as small as 0.004 in
(0.1016 mm) are possible. In order to be able to start cutting from somewhere else than the edge,
a pierce is done before every cut. Piercing usually involves a high-power pulsed laser beam which
slowly makes a hole in the material, taking around 5–15 seconds for 1/2-inch-thick (13 mm) stainless
steel, for example The parallel rays of coherent light from the laser source often fall in the range between
1/16 inch to 1/2 inch (1.5875 mm to 12.7 mm) in diameter. This beam is normally focused and intensified
by a lens or a mirror to a very small spot of about 0.001 inch (0.0254 mm) to create a very intense
laser beam. In order to achieve the smoothest possible finish during contour cutting, the direction of
beam polarization must be rotated as it goes around the periphery of a contoured workpiece.
For sheet metal cutting, the focal length is usually between 1.5 inches and 3 inches (38.1 mm and
76.2 mm).

Bending
NC / CNC
is a process by which metal can be deformed by plastically deforming the material and
changing its shape. The material is stressed beyond the yield strength but below the ultimate tensile
strength. The surface area of the materila does not change much. Bending usually refers to
deformation about one axis.
Bending is a flexible process by which many different shapes can be produced. Standard die
sets are used to produce a wide variety of shapes. The material is placed on the die, and
positioned in place with stops and/ or gages. It is held in place with hold- downs. The upper
part of the press, the ram with the appropriately shaped punch descends and forms the
v- shaped bend.
Bending is done using Press Brakes. Press Brakes normally have a capacity of 20 to 200 tons to
accommodate stock from 1m to 4.5m (3 feet to 15 feet). Larger and smaller presses are used
for specialized applications. Programmable back gages, and multiple die sets available
currently can make for a very economical process.

Welding
MAG / TIG
Tungsten Inert Gas (TIG) WeldingMetal Inert Gas (MIG) Welding
Uses a consumable wire electrode during the welding process that is fed from a spool.
Provides a uniform weld bead.
Produces a slag-free weld bead.
Uses a shileding gas - argon, argon - 1to 5% oxygen, argon - 3 to 25% CO2
and a combination argon/helium gas.
Is considered a semi-automatic welding process.
Allows long welding in all positions.
Requires less operator skill than TIG welding.
Allows long welds to be made without starts or stops.
Needs a little clean up.
The illustration that follows provides a look at a typical MIG welding process showing an arc that is
formed between the wire electrode and the workplace. During the MIG welding process,
the elctrode melts within the arc and becomes deposited as filler material. The shielding gas that is
used prevents atmospheric contamination from atmospheric contamination and protects the weld
during soldification. The shielding gas also assists with stabilizing the arc which provides a smooth
transfer of metal from the weld wire to the molten weld pool.

Fire cabinets assist in the protection of fire equipment from degradation due to
weather exposure, and also augment security, lessening the impact of vandalism and
public mischief. They are generally painted in RAL 3000 “Signal Red” which enhances
visibility. this assist in locating fire protection equipment in the event of an emergency,
and in areas of high vehicular traffic (i.e. car parks) it lessens the likehood of accidental
damage. USMI can custom make any type of cabinet to suit any fire protection
application. We can cater for unique sizes, configurations, colors, material, gauge,
stenciling etc.. As cabinets are constructed from corrosion resistant Zinc seal they
require very little maintenance.
