STAINLESS STEEL - General Information
The many unique values provided by stainless steel make
it a powerful candidate in materials selection. Engineers,
specifiers and designers often underestimate or overlook
these values because of what is viewed as the higher
initial cost of stainless steel. However, over the total life of
a project, stainless is often the best value option.
What is Stainless Steel?
Stainless steel is essentially a low carbon steel which
contains chromium at 10% or more by weight. It is this
addition of chromium that gives the steel its unique
stainless, corrosion resisting properties.
The chromium content of the steel allows the formation
of a rough, adherent, invisible, corrosion-resisting
chromium oxide film on the steel surface. If damaged
mechanically or chemically, this film is self-healing,
providing that oxygen, even in very small amounts,
is present. The corrosion resistance and other useful
properties of the steel are enhanced by increased
chromium content and the addition of other elements
such as molybdenum, nickel and nitrogen.
There are more than 60 grades of stainless steel.
However the manufacturing of TOPFIX
products are with the use of two grades. Grade 1.4301
used for the majority of our products and in normal
working conditions. Grade 1.4401 used in areas of
high corrosive nature. Grade 1.4401 has to be specified
and is more expensive.
Benefits of Stainless Steel
Corrosion resistance
Lower alloyed grades resist corrosion in atmospheric and
pure water environments, while high-alloyed grades can
resist corrosion in most acids, alkaline solutions, and
chlorine bearing environments, properties which are
utilized in process plants.
Fire and heat resistance
Special high chromium and nickel-alloyed grades resist
scaling and retain strength at high temperatures.
Hygiene
The easy cleaning ability of stainless makes it the first
choice for strict hygiene conditions, such as hospitals,
kitchens, abattoirs and other food processing plants.
Aesthetic appearance
The bright, easily maintained surface of stainless steel
provides a modern and attractive appearance.
Strength-to-weight advantage
The work-hardening property of austenitic grades, that
results in a significant strengthening of the material from
cold-working alone, and the high strength duplex
grades, allow reduced material thickness over
conventional grades, therefore cost savings.
Ease of fabrication
Modern steel-making techniques mean that stainless can
be cut, welded, formed, machined, and fabricated as
readily as traditional steels.
Impact resistance
The austenitic microstructure of the 300 series provides
high toughness, from elevated temperatures to far below
freezing, making these steels particularly suited to
cryogenic applications.
Long term value
When the total life cycle costs are considered, stainless is
often the least expensive material option.
