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.
MONEL K500 is a nickel-copper alloy, precipitation hardenable through additions of aluminum and titanium.
Monel K500 pipe bend and elbow are resistant to a sour-gas environment
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.
316 stainless steel pipe bend can be used with seawater, provided precautions are taken to avoid crevice corrosion developing under sediments, precipitation and biofouling, and at designed-in crevices.
Grade 316, and grade 304, may suffer stress corrosion cracking in solutions containing chloride ions at temperatures over about 60¡ãC. Stress corrosion cracking should be considered for all corrosion services where the corrosive liquid may contain chloride.
316 pipe bend is the superior choice for high corrosion and high temperature applications. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won¡¯t decay, unlike with 316 stainless steel.
Grade 316 pipe bend is readily workable, by the standard methods of sheet metal working, with the exception that it cannot be oxygen cut. Plasma cutting is normal. The deep drawing capability of grade 316 is outstanding, because of its high austenite stability.
316 stainless steel pipe bend has very low responsiveness to magnetic fields. Unlike basic stainless steels, which are ferromagnetic, most stainless steel varieties (including 316) are austenitic ¡ª or effectively nonmagnetic.
Grade 316 pipe bend is relatively easy to machine, although more difficult than carbon steel. More power is required to machine grade 316. Cutting speed should be lower, the feed higher, tooling and equipment heavier.
The 316 stainless steel pipe bends can undergo processes, like cold forming and welding, where the austenitic crystal structure is transformed into ferromagnetic martensite. 316L steel is more susceptible to gaining some degree of magnetism.
The machinability of 316 pipe bend is about 60% that of AISI B1112 resulphurised free cutting carbon steel. A free machining version of 316 is available as bar.
316 pipe bend is primarily used in construction and infrastructure because it is strong, resistant to pitting, and corrosion resistant in most circumstances.
Grade 316 stainless steel pipe bend is readily weldable by most fusion techniques (GTAW / TIG, GMAW / MIG / MAG, MMAW / stick, SAW), with no preheat, postheat or control of interpass temperature needed.
Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance.
316 stainless steel pipe bend contains an addition of molybdenum that gives it improved corrosion resistance. This is particularly apparent for pitting and crevice corrosion in chloride environments.
The austenitic structure of 316 stainless steel pipe bend gives excellent toughness, even at cryogenic temperatures.
316 pipe bend contains a minimum 2.0% molybdenum which makes it much more corrosion resistant than 304 however, as it is a more expensive element, generally makes 316 a more expensive grade of metal.
Stainless steel as a family of metals is very corrosion resistant but with the addition of molybdenum into 316, this increases the grades ability to withstand harsh environments. Often referred to as marine grade, 316 pipe bend is suitable for use in environments that are more aggressive than ambient although care should still be taken to clean the metal regularly to prolong its service life.
Type 316 steel is an austenitic chromium-nickel stainless steel that contains between two and 3% molybdenum.
