Carbon steel is steel where
the main interstitial alloying constituent is carbon. As the
carbon content rises, steel has the ability to
become harder and stronger through heat treating.
Stainless Steel Coils
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.
Grade 304-L, the low carbon version of 304, does not require
post-weld annealing and so is extensively used in heavy gauge
Stainless Steel Coils
has better overall corrosion resistant properties than Grade
304, particularly higher resistance to pitting and crevice
corrosion in chloride environments. Grade 316L, the low carbon
version of 316 and is immune from sensitisation . Thus it is
extensively used in heavy gauge welded components.
Stainless Steel Coils
317 stainless steel is a modified version of 316
stainless steel. It has high strength and corrosion resistance.
Grade 317 stainless steel is tougher than 304 stainless steel.
Grade 317 stainless steel can be welded using fusion and
resistance methods. 317-L filler metal can be used to obtain good
Stainless Steel Coils
321 has the basic austenitic 18/8 steel (Grade 304)
stabilised by Titanium or Niobium. This grade is used because it
is not sensitive to intergranular corrosion after heating. 321
is the grade of choice for applications in the temperature range
of up to about 900°C, combining high strength, resistance to
scaling and phase stability with resistance to subsequent
Copper and copper alloys are some of the
most versatile engineering materials available. The combination
of physical properties such as strength, conductivity, corrosion
resistance, machinability and ductility make copper suitable for
a wide range of applications.
20 is a nickel-chromium-molybdenum stainless steel alloy
developed for applications involving sulfuric acid. Its
corrosion resistance also finds other uses in the chemical,
food, pharmaceutical, and plastics industries. Alloy 20 resists
pitting and chloride ion corrosion and its copper content
protects it from sulfuric acid. Alloy 20 is not a SS but a
Inconel 600 is a Nickel-Chromium alloy with good
resistance to oxidation and corrosion at high temperatures. When
heated, Inconel forms a thick, stable, passivating oxide layer
protecting the surface from further attack. Inconel retains
strength over a wide temperature range, attractive for high
temperature applications. Inconel is often encountered in
Inconel 825 is a Nickel-Iron-Chromium alloy with
additions of Molybdenum and Copper. It has excellent resistance
to both reducing and oxidising acids, to stress-corrosion
cracking and to localised pitting and crevice corrosion. It is
also especially resistant to sulphuric and phosphoric acids.
400 is a Nickel-Copper alloy with high strength and
excellent corrosion resistance in a range of acidic and alkaline
environments and especially suitable for reducing conditions. It
also has good ductility and thermal conductivity.
Admiralty brass contains 30% zinc, and 1% tin which
inhibits dezincification in many environments. Brass has higher
malleability than bronze or zinc.
Hastelloy C-276 is a Nickel-Molybdenum-Chromium alloy
with the addition of Tungsten, has excellent corrosion
resistance in a wide range of corrosive media and is especially
resistant to pitting and crevice corrosion. Used in any
environment that requires resistance to heat and corrosion but
where the mechanical properties of the metal must be retained.
Hastelloy B is a wrought nickel-molybdenum alloy that
can be used in the ‘as welded’ condition. This alloy has
excellent resistance to all temperatures and concentrations of
hydrochloric acid. Additionally, it has good stress corrosion
cracking and pitting resistance as well. However, due to the
presence of high molybdenum content, this alloy is expensive.
alloys are metals which contain a mixture of titanium and other
chemical elements. Such alloys have very high tensile strength
and toughness (even at extreme temperatures). They are light
weight, have extraordinary corrosion resistance and the ability
to withstand extreme temperatures.
properties include good appearance, ease of fabrication, good
corrosion resistance, low density, high strength-to-weight ratio
and high fracture toughness. Aluminum has a density around
one-third that of steel or copper, making it one of the lightest
commercially available metals.
Copper-nickel alloy with an alpha phase structure. Small amounts
of iron and manganese are added to improve corrosion resistance
in high-velocity (from 1 to about 3.5 m/s) waters,
including seawater. The alloy is relatively insensitive to
stress corrosion. It has good cold- and hot- working properties
and is readily weldable.
70/30 copper nickel alloys have great resistance to sea
water-related corrosion due to the presence of significant
amounts of manganese and iron. Their high oxidation resistance
is seen in moist air and steam. These alloys are thermally
stable and possess moderate strength even when the temperature
is high. The corrosion resistance and strength of these alloys
are improved by the addition of manganese, iron, niobium, and or
80/20 Copper-nickel alloys have very good resistance to
biofouling and marine corrosion, and possess good fabricability.
Copper gains more strength and corrosion resistance when nickel
is added to it.
Nickel with good mechanical properties over a wide range
of temperature and excellent resistance to many corrosives, in
particular hydroxides. Good resistance to corrosion in acids and
alkalis and is most useful under reducing conditions.
Outstanding resistance to caustic alkalis. In acid, alkaline and
neutral salt solutions the material shows good resistance, but
in oxidizing salt solutions severe attack will occur.
stainless is a mixed microstructure of austenite and ferrite
(50/50) which has improved strength over ferritic and austenitic
steel grades with similar corrosion resistance qualities. 2205
is the most common duplex alloy which contains 22% chromium and
5% nickel. Greater tensile and yield strength with similar
corrosion resistance to type 304 stainless.
stainless like Duplex, is a mixed microstructure of
austenite and ferrite (50/50) which has improved strength over
ferritic and austenitic steel grades. The main difference is
that Superduplex has a higher Molybdenum and Chromium content
which gives the material greater corrosion resistance.
6X N Coils
alloy is a superaustenitic stainless steel. It exhibits far
greater resistance to chloride pitting, crevice corrosion and
stress corrosion cracking. The high nickel and molybdenum
contents of the AL-6XN alloy give it good resistance to chloride
stress-corrosion cracking. This metal is commonly used in high
temperature and low ph applications in food processing.
