Materials

Hastelloy B2 pipe bend has excellent resistance to all temperatures and concentrations of hydrochloric acid.

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 pipe bend has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack.

Alloy B2 pipe bend provides resistance to pure sulfuric acid and a number of non-oxidizing acids.

These salts may develop when hydrochloric acid comes in contact with iron and copper. Therefore, if this alloy is used in conjunction with iron or copper piping in a system containing hydrochloric acid, the presence of these salts could cause the alloy to fail prematurely.

Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.

Hastelloy B2 pipe bend resists the formation of grain boundary carbide precipitates in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded condition.

The heat-affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.

Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.

Hastelloy B2 pipe bend is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.

Applications in the chemical process industry involving sulfuric, phosphoric, hydrochloric and acetic acid.

MONEL K500 retains the excellent corrosion resistant characteristics of 400 and has enhanced strength and hardness after precipitation hardening when compared with 400.

Alloy 400 pipe bend and elbow have excellent corrosion resistance together with increased strength and hardness.

Alloy K500 has approximately three (3) times the yield strength and double the tensile strength when compared with 400. MONEL K500 can be further strengthened by cold working before the precipitation hardening.

Monel K500 pipe bend and elbow has excellent mechanical properties from sub-zero temperatures up to about 480C.

Monel K500 pipe bend and elbow have corrosion resistance in an extensive range of marine and chemical environments. From pure water to non-oxidising mineral acids, salts and alkalis.

Monel K500 pipe bend and elbow are usually used in propeller, pump shafts, pumps, valves used in the manufacture of perchlorethylene, and chlorinated plastics.

Monel nickel-copper alloy K-500 pipe bend and elbow combine the excellent corrosion resistance characteristic of Monel alloy 400 with the added advantages of greater strength and hardness.

The increased properties are obtained by adding aluminum and titanimum to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated thoughout the matrix.

Typical applications for alloy K-500 pipe bend and elbow are pump shafts and impellers; doctor blades and scrapers; oil-well drill collars and instruments; electronic components; springs; and valve trim.

The corrosion resistance of Monel alloy K-500 is subtantially equivalent to that of alloy 400 except that, when in the age-hardened condition, alloy K-500 has a greater tendency toward stress-corrosion cracking in some environments.

Monel alloy K-500 pipe bend and elbow have been found to be resistant to a sour-gas environment. After 6 days of continuous immersion in saturated (3500ppm) hydrogen sulfide solutions at acidic and basic pH’s (ranging from 1.0 to 11.0), U-bend specimens of age-hardened sheet show no cracking.

The combination of very low corrosion rates in high-velocity sea water and high strength make alloy K-500 pipe bend and elbow particularly suitable for shafts of centrifugal pumps in marine service.

Typical application for MONEL K500 which takes advantage of high strength and corrosion resistance are pump shafts, impellers, propeller shafts, valve components for ships and offshore drilling towers, bolting, oil well drill collars and instrumentation components for oil and gas production. It is particularly well suited for centrifugal pumps in the marine industry because of its high strength and low corrosion rates in high-velocity seawater.

MONEL K500 is non-magnetic. MONEL K500 should be annealed when welded and the weldment then stress relieved before aging.

This nickel-copper alloy is precipitation hardenable due to the addition of aluminum and titanium. It combines the corrosion resistance of Monel 400 with the added benefits of superior strength and hardness (derived from its age-hardenability). Monel K-500 is also known for its ease of fabrication compared to other superalloys, and the fact that it is essentially nonmagnetic even at low temperatures.

Monel K500 pipe bend and elbow are virtually nonmagnetic, even at quite low temperatures

MONEL K500 is a age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance.

Monel K500 pipe bend and elbow are exceptionally good dimensional stability.
