Description
Hastelloy B2 is a solid solution strengthened, nickel‐molybdenum alloy, with significant resistance to reducing environments
like hydrogen chloride gas, and sulfuric, acetic and phosphoric acids. Molybdenum is the primary alloying element which
provides significant corrosion resistance to reducing environments. This nickel steel alloy can be used in the as‐welded
condition because it resists the formation of grain‐boundary carbide precipitates in the weld heat‐affected zone. This nickel
alloy provides excellent resistance to hydrochloric acid at all concentrations and temperatures. In additions, Hastelloy B2 has
excellent resistance to pitting, stress corrosion cracking and to knife‐line and heat‐affected zone attack. Alloy B2 provides
resistance to pure sulfuric acid and a number of non‐oxidizing acids. Some of the applications of Hastelloy B2 are as follows.
Chemical processes
Vacuum furnaces
Mechanical components in reducing environments

Description
Hastelloy N alloy (UNS N10003) is a nickel‐base alloy that was invented at Oak Ridge National Laboratories as a container
material for molten fluoride salts. It has good oxidation resistance to hot fluoride salts in the temperature range of 1300 to
1600°F (704 to 871°C). In tests of over two years duration, corrosion attack on Hastelloy N alloy in molten fluoride salts at
temperatures up to 1300°F (704°C), was less than one mil per year. It is expected that alloy N will be most useful in
environments involving fluorides at high temperatures; however, the alloy compares favorably with other Hastelloy alloys in
various corrosive media, as shown in the table of penetration rates. It is especially suggested that the alloy be tested in molten
halides of zirconium, beryllium, lithium, sodium, potassium, thorium or uranium.

Description
Hastelloy S alloy (UNS N06635) is a nickel‐base, high‐temperature alloy with a unique combination of properties. It has excellent
thermal stability, low thermal expansion and excellent oxidation resistance to 2000°F (1093°C). In addition, the alloy has good
high‐temperature and thermal fatigue strength. S alloy retains its strength and ductility after aging at temperatures of 800 to
1600°F (427 to 871°C). S alloy was developed for applications involving severely cyclical heating conditions where components
must be capable of retaining their strength, ductility, and metallurgical integrity after long‐time exposure. It is used extensively
as seal rings in gas turbine engines where its low thermal expansion coefficients is also important. All wrought forms of S alloy
are supplied in the solution heat treated condition unless otherwise specified. The standard heat‐treatment is 1950°F (1066°C)
followed by cooling in air or hydrogen. Since the alloy is very stable, cooling rates from slow‐fumace cooling to rapid ice‐brine
quenching have virtually no effect on the mechanical properties.

Availability
Hastelloy S is available in various forms like sheets, strips, plates, rods, bars, wires, tubes, forgings, welding products etc.

Description
Hastelloy G‐30 alloy (UNS N06030) is a nickel‐chromium‐iron material highly resistant to “wet process” phosphoric acid (P2O5).
P2O5 is one of the most important industrial chemicals, being the primary source of phosphorus for agrichemical fertilizers. G‐
30 alloy is also moderately resistant to chloride‐induced localized attack, which can be a problem beneath deposits in the
evaporators used to concentrate P2O5. Furthermore, G‐30® alloy is less susceptible to chloride‐induced stress corrosion
cracking than the stainless steels. As a result of its high chromium content, G‐30 alloy is also very resistant to other oxidizing
acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, such as hydrochloric
and sulfuric, as a result of its appreciable molybdenum and copper contents. Applications include P2O5 evaporator tubes and
nitric acid‐based, metal pickling hardware.

Description
Hastelloy G‐35 alloy (UNS N06035) was developed to resist “fertilizer‐grade” phosphoric acid (P2O5), which is used in the
production of fertilizers. Tests in real‐world solutions indicate that G‐35 alloy is far superior to other metallic materials in this
acid. It was also developed to resist localized attack in the presence of chlorides, since this can be a problem beneath deposits
in evaporators used to concentrate “fertilizer‐grade” phosphoric acid. Furthermore, G‐35 alloy is much less susceptible to
chloride‐induced stress corrosion cracking than the stainless steels and nickel‐chromium‐iron alloys traditionally used in
“fertilizer‐grade” phosphoric acid. As a result of its very high chromium content, G‐35 alloy is extremely resistant to other
oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, as a result
of its appreciable molybdenum content, and, unlike other nickel‐chromium‐molybdenum alloys, it is very resistant to “caustic
de‐alloying” in hot sodium hydroxide. Applications include P2O5 evaporator tubes.

Description
HASTELLOY C‐2000 alloy (UNS N06200) is unique among the versatile nickel‐chromium‐molybdenum materials in having a

maximize its resistance to oxidizing chemicals and process streams contaminated with ferric ions and dissolved oxygen. Like
other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in
chloride‐bearing solutions (a form of degradation to which the austenitic stainless steels are prone). It is able to withstand a
wide range of oxidizing and non‐oxidizing chemicals, and exhibits outstanding resistance to pitting and crevice attack in the
presence of chlorides and other halides. Typical chemical process industry (CPI) applications include reactors and heat
exchangers.
