About Hastelloy1
Hastelloy is a registered trademark name of Haynes International, Inc. The Hastelloy trademark is applied as the prefix name of a range of corrosion-resistant metal alloys under the material term ※superalloys§ or ※high-performance alloys§.
Within corrosion applications Hastelloy alloys are often chosen due to their relatively attractive price/performance ratio. In many corrosion media only Tantaline shows a dramatically better cost/performance ratio than Hastelloy.
The predominant Hastelloy alloying ingredient is metal nickel. Other alloying ingredients are added to Hastelloy includin varying percentages of the elements molybdenum, chromium, cobalt, iron, copper, manganese, titanium, zirconium, aluminum, carbon, and tungsten.
The primary function of the Hastelloy alloys is that of effective survival under high-temperature, high-stress service in a moderately to severely corrosive, and/or erosion prone environment. Hastelloy alloys are used for many applications including pressure vessels, nuclear reactors, chemical reactors, as pipes and valves in chemical industry.
Hastelloy B-3
HASTELLOY B-3 alloy is a member of the nickel-molybdenum family of Hastelloy alloys. Hastelloy B-3 is the alloy in the Hastelloy family that shows best resistance to hydrochloric acid.
Hastelloy C-276
HASTELLOY C-276 alloy is a nickel-molybdenum-chromium wrought alloy that is generally used as corrosion-resistance. Hastelloy c-276 (Hastelloy C276) is among the more well known Hastelloy grades for general corrosion service. Hastelloy C-276 alloy is an improved wrought version of Hastelloy alloy C.
Hastelloy C-4
HASTELLOY C-4 alloy is a nickel-chromium-molybdenum Hastelloy alloy with good high-temperature stability. The Hastelloy C-4 is an Hastelloy grade, that resists the formation of grain-boundary precipitates in weld heat-affected zones. Hastelloy C-4 alloy also has excellent resistance to stress-corrosion cracking and to oxidizing atmospheres. Hastelloy C-4 is also used in a varity of chemical process environments.
Hastelloy G
Hastelloy G is an nickel-chromium-iron-molybdenum alloy developed for corrosion resistance in both oxidizing and reduceing media. Hastelloy G shows good resistance to sulfuric and phosphoric acids. Hastelloy G may further handle both acid and alkaline solutions.
Hastelloy X
HASTELLOY X alloy - a nickel-chromium-iron-molybdenum alloy - has been developed to combine oxidation resistance, fabricability and high-temperature strength. Hastelloy X is also It has also been found to be resistant in petrochemical applications.
SS 316L is an austenitic Chromium-Nickel stainless steel with superior corrosion
Resistance.The low carbon content reduces susceptibility to carbide precipitation during
Welding. This permits usage in severe corrosive environments such as isolator Diaphragms.

Grade 416, also called UNS S41600 is a Martensitic grade of stainless steel. The Martensitic stainless steels have been manufactured as an alloy, which could be toughened using heat treatment and it also will be corrosion resistant, though it is not as resistive to corrosion as the ferritic or austenitic stainless steels. Stainless Steel 416 has respectable wear resistant, and is magnetic; it also is highly machinable. Its other qualities include: non-galling and non-seizing properties, sensible strength in hardened and tempered state and resistance to gently corrosive surroundings. Generally it＊s ordered in T (tempered), H (hardened) and A(annealed) conditions

HASTELLOY C-276/UNS N10276/2.4819
Alloy C-276 (UNS N10276) is generally considered the most versatile heat resistant and corrosion resistant alloy available. A Ni-Cr-Mo-W alloy, C-276 offers excellent resistance to pitting, stress-corrosion cracking, and high temperature atmospheres. Additionally, due to its low carbon content, C-276 resists the formation of grain boundary precipitates in the weld-affected zone making it useful for applications in the as-welded condition.

Heat-TreatmentWrought forms of HASTELLOY C-276 alloy is furnished in the solution heat-treated condition unless otherwise specified.C-276 alloy is normally solution heat-treated condition unless otherwise specified.C-276 alloy is normally solution heat-treated at 2050∼F (1121∼C) and rapid quenched. If possible, parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation.
HASTELLOY C-22/UNS N06022/2.4602
Alloy C-22 (UNS N06022) is very similar to Alloy C-276 (UNS N10276) and is also a good heat resistant and corrosion resistant alloy. A Ni-Cr-Mo-W alloy, C-22 offers resistance to pitting, stress-corrosion cracking, and crevice corrosion.
Hastelloy C-22, (like C-276) is used in pollution control, chemical processing, pulp and paper production, waste treatment, marine seawater applications, etc. When comparing the two alloys, there is little difference in corrosion resistant performance with one exception; C-22 shows an improvement over C-276 when used in certain saturated wet chlorine environments. However, in most cases because of its supp
