Commonly Cast Stainless Steel Alloys:
Stainless Steel 304(1.4308)
This is the most common stainless steel and is applied in different
applications. It consists of at least 18% chromium and 8% nickel
and has no
magnetic properties within its austenitic structure.
Stainless Steel 304L(1.4309)
Corresponds to stainless steel 304. The ‘L’ stands for ‘low
carbon’, so this stainless steel has a lower carbon amount to
increase weldability and to
limit the corrosion sensitivity after welding.
Stainless Steel 316(1.4408)
A better, but more expensive type of corrosion resistant steel is
stainless steel 316. This alloy contains at least 16% chromium, 10%
nickel and 2%
molybdenum. Because of the addition of molybdenum, this stainless
steel type is better defended against salt corrosion and acids, and
applied in chemical industries.
Stainless Steel 316L(1.4409)
Comparable to stainless steel 316 but with a lower carbon level to
increase weldability of the stainless steel.
A high quality stainless steel which is regularly used in the
aircraft industry. It is characterized by a high tensile strength,
hardness, toughness and is
also corrosion resistant.
Natural corrosion resistance
Corrosion is a natural phenomenon. Pure elements always react with
the surrounding environment, which is why so few elements are
found in their pure form. Iron is no exception.
In wet or humid conditions iron reacts with the oxygen contained in
water to form iron oxide, also known as rust. The red flaky oxide
easily—exposing more material to corrosion. Iron and standard
carbon steels are highly susceptible to this type of corrosion.
Stainless steel has the innate ability to form a passive layer that
prevents corrosion. The secret?
The chromium found in all stainless steels reacts quickly with
oxygen environments, much the same as iron. The difference,
however, is that only a
very fine layer of chromium will oxidize (often only a few
molecules in thickness). Unlike flaky and unstable iron oxide,
chromium oxide is highly
durable and non-reactive. It adheres to stainless steel surfaces
and won't transfer or react further with other materials. It is
also self-renewing—if it’s
removed or damaged, more chromium will react with oxygen to
replenish the barrier. The higher the chromium content, the faster
the barrier repairs
Once oxidized, or passivized, stainless steel typically rusts at a
very low rate of less than 0.002 inches per year. When kept in its
stainless steel offers clean and bright surfaces ideal for many
building and landscape designs.
304 Stainless Steel
304 stainless steel is the most common form of stainless steel used
around the world, largely due to its excellent corrosion resistance
and value. It
contains between 16 and 24 percent chromium and up to 35 percent
nickel, as well as small amounts of carbon and manganese.
The most common form of 304 stainless steel is 18-8, or 18/8,
stainless steel, which contains 18 percent chromium and 8 percent
304 can withstand corrosion from most oxidizing acids. That
durability makes 304 easy to sanitize, and therefore ideal for
kitchen and food
applications. It is also common in buildings, décor, and site
304 stainless steel does have one weakness: it is susceptible to
corrosion from chloride solutions, or from saline environments like
Chloride ions can create localized areas of corrosion, called
"pitting," which can spread beneath protective chromium barriers to
structures. Solutions with as little as 25 ppm of sodium chloride
can begin to have a corrosive effect.
316 Stainless Steel
316 grade is the second-most common form of stainless steel. It has
almost the same physical and mechanical properties as 304 stainless
and contains a similar material make-up. The key difference is that
316 stainless steel incorporates about 2 to 3 percent molybdenum.
increases corrosion resistance, particularly against chlorides and
other industrial solvents.
316 stainless steel is commonly used in many industrial
applications involving processing chemicals, as well as high-saline
environments such as
coastal regions and outdoor areas where de-icing salts are common.
Due to its non-reactive qualities, 316 stainless steel is also used
manufacture of medical surgical instruments.
Alternative 300-series grades can contain up to 7 percent
molybdenum. They provide even better chloride resistance, but such
resistance is only necessary in industrial or high concentration
Both 304 and 316 stainless steels (as well as other 300-series
grades) use nickel to maintain an austenitic composition at lower
Austenitic steels ensure a versatile balance of strength,
workability, and corrosion resistance, making them ideal for
outdoor architectural features,
surgical instrumentation, and food processing equipment.
A large volume of stainless steel produced today (especially 316
stainless steel) can be found in products related to the food and
industries. Stainless steel is commonly found in commercial
kitchens and food processing plants as it serves a variety of
It can be easily formed and fabricated into shapes needed to
produce a variety of equipment and machinery, such as cooking
hoods, tanks, and hoppers.
It is available in a wide range of decorative and polished
It can withstand shock and abrasive conditions found in kitchens or
food processing plants.
It can be easily cleaned, and can withstand repeated washing with
the many chemicals and detergents employed to meet public health
It does not react to the alkalis and acids found in milk, cooked
foods, vegetables, and food additives.
The ultimate benefits of stainless steel include a long service
life that will retain an attractive, clean finish. Properly cared
for and cleaned stainless
steels present a low maintenance cost
