Careful formulation of the weld wire composition ensures the optimum combination of weld strength and corrosion resistance, achieved by over-alloying the wire with Nickel to maintain the correct (austenite / ferrite) phase balance. Monel K500 supplier in India offer Low cost of N05500 Nickel alloy, Monel K500 Products, Check Alloy k500 properties, chemical composition, melting point, heat treatment and Monel K500 … Huntington Alloys was developing a new kind of Monel by trying to add other elements to its chemistry for increased strength. In its standard annealed condition it is easy to form and fabricate with no requirements for additional heat treatments to re-balance the alloy.  It is often used in applications like propeller shafts and pumps shafts, the propellers and impellers themselves, and as condenser tubes where cavitation and erosion resistance are important. Its basic composition is similar to that of Monel®400 but the alloying additions make it age hardenable under controlled conditions of temperature and time. The maximum hot working temperature is 2100°F while cold forming can only be accomplished on annealed materials. It achieves higher strengths than other alternative corrosion resistant alloys, offering the potential to reduce section size and therefore weight and cost. Monel Alloy k-500 Nuts Specification. This led to speculation that the alloy specimen was possibly not a solid solution like it was considered to be. It achieves higher strengths than most other stainless steels and alternative corrosion resistant alloys, offering the potential to reduce section size and therefore weight and cost. In 1924, an unusually hard specimen was examined and showed a eutectic structure similar to oxidized copper. Monel K500 bolts will give you similar corrosion resistance as Monel 400 bolts, but with added strength. Nickel Copper alloys are known to have excellent corrosion resistance in certain media and good physical properties. The increase in strength and hardness is a result of the precipitation hardening capability gained … Alloy 316L is an austenitic stainless steel supplied in the hot worked and annealed condition. Monel K-500 is readily welded by GMAW (MIG), GTAW (TIG), SMAW (manual) and SAW processes. These Monel K500 Round Tubes are identical except for the higher level of carbon, and the addition of up to 1.20 percent aluminium and titanium. The applications also span into centrifugal pumps used in the marine industry, propeller shafts and valve components and some other ship and boat accessories. As a super duplex stainless steel, it combines the desirable aspects of both austenitic and ferritic grades. Alloy 400 is a nickel-copper (Monel® is Special Metals Corporation’s trademark for a family of Nickel-Copper alloys) single-phase alloy most commonly supplied in hot worked and annealed condition. Alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium (NiCr21Mo). But there is another Nickel Copper alloy, one that with a slightly different chemistry has shown improved mechanical properties over Alloy 400 and the ability to be hardened through heat treatment. This website uses cookies to improve your experience while you navigate through the website. It possesses low permeability and is non-magnetic at temperatures as low as -150 degrees F (-101 Degrees C). Corrosion Materials, Inc. The range of annealing for the heat treatment of Monel 400 is between temperatures of 1300 to 1800 °F. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >40. The combination of very low corrosion rates in high-velocity sea water and high strength make it well-suited for marine shafts in stagnant or slow-moving sea water, fouling may occur followed by pitting but this pitting slows down after a fairly rapid initial attack. Nickelvac K-500™ is heat treated by annealing. Alloy 254, is a high alloy austenitic stainless steel supplied in the hot worked and annealed condition. As a duplex stainless steel, it combines the desirable aspect of properties of both austenitic and ferritic grades. Monel K500 contains additional aluminum and titanium content, and is specially heat treated under controlled conditions to precipitate the formation of submicroscopic particles of Ni 3 (Ti, Al) throughout the matrix, making it harder and stronger. Monel Alloy K-500 is a precipitation- hardened Nickel-copper alloy that merges the corrosion resistance of Monel alloy 400 with higher strength and hardness. This Nickel-Copper alloy is precipitation hardenable, due to the additions of Aluminium and Titanium. (Sandvik SAF2507 is a registered trademark of Sandvik Intellectual Property AB). Machining Monel K500: Monel K-500 has the same corrosion resistance as Monel 400, but has higher mechanical strength and hardness. With the exception of the higher carbon level and the addition of up to 1.20 percent aluminum and titanium, these Monel K500 … K500 Data Sheet Machinability Alloy K500 can be readily machined in the annealed or hot worked and quench condition. In addition to sulfides, Sanmac steels contain oxide inclusions that improve chip breaking and reduce tool wear. MONEL® alloy 400 2 Table 3 - Thermal Properties of MONEL Alloy 400 The nominal room-temperature tensile properties of MONEL alloy 400 are shown in Table 4. Both cold worked and hot worked Alloy 400 may be annealed or stress relieved for the desired combination of strength and ductility and to minimized distortion during subsequent machining. The Monel K500 heat treatment makes it harder. Non-ferrous alloys overall are less sparking than alloys containing a considerable larger amount of iron. 1.Introduction to Monel K500 alloy. The addition of Nb, Ti, Al and Ni form a series of precipitates during the controlled solution annealing and ageing process steps, resulting in a significant increase in strength and hardness. The recommended practice is to machine slightly oversize, age harden and finish to size. ANIL METALS have great pleasure to introduce ourselves as one of the leading stockiest and supplier of Stainless Steel in various grades such as AISI 304, 304L, 316, 316L, 321, 310, 410 & 430 etc., Hast Alloy, Alloy 20, Monel, Incoly, 904L and other special alloys. But there is another Nickel Copper alloy, one that with a slightly different chemistry has shown improved mechanical properties over Alloy 400 and the ability to be hardened through heat treatment. As a super duplex stainless steel, the SAF2507 combines the desirable aspects of both austenitic and ferritic grades. Sanmac® 316L is an improved-machinability austenitic stainless steel bar. Once hardened, cold working and machining become very tough. It possesses low permeability and is non-magnetic at temperatures as low as -150 degrees F (-101 Degrees C).  It was then aged overnight and its hardness increased significantly – up to HB275. Springs, pumps, valves, and fasteners. The aluminium and titanium combine to form microscopic precipitates, which can be controlled through heat treatment. These enhanced properties are mainly achieved by adding elements of aluminum and titanium and age hardening on the basis of nickel as a … Adding 2.3 to 3.5% Aluminum and point 35 to point 85 % Ti to the basic composition creates an alloy that can be heat treated to precipitate these elements and increase its strength. Albeit, the most typical temperature range at which the heat treatment of Monel 400 can be carried out is between 1600 to 1800 °F. Alloy K-500 provides a yield strength three times higher than Alloy 400. Monel Alloy K-500 is a precipitation- hardened Nickel-copper alloy that merges the corrosion resistance of Monel alloy 400 with higher strength and hardness. With regards to corrosion resistance, Alloy K500 has relatively the same excellent corrosion resistance as Alloy 400 except when used in the aged condition and can have a tendency towards stress corrosion cracking in some environments. Nickelvac K-500 is forged at 1038 to 1149°C (1900 to 2100°F) followed by quenching in water. Monel 400 heat treatment needs to be carried out in an atmosphere that is sulfur-free reducing. Its basic composition is similar to that of Monel®400 but the alloying additions make it age hardenable under controlled conditions of temperature and time. It possesses low permeability and is non-magnetic at temperatures as low as -150 degrees F (-101 Degrees C). November 2020 VDM® Alloy K-500 2 VDM® Alloy K-500 is a nickel-copper alloy that can be age-hardened due to additions of aluminum and titanium.
