Hastelloy Fasteners provides resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. Inconel can be used for many applications such as marine, power, chemical processing, pollution control, paper processing, and waste disposal industries. Hastelloy contains chromium, molybdenum, tungsten, and iron which makes the alloy resistant to corrosion in stagnant or flowing seawater. The alloy is formed by gas tungsten-arc, gas metal-arc, and shielded metal-arc processes.

Mahesh Enterprises is India’s one of the leading Fasteners manufacturers & Suppliers in Alloy 20. It is also known as Carpenter 20. It is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulphuric acid. It also contains niobium for stabilization against sensitization and resultant corrosion. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Although originally designed for use in sulphuric acid related industries, Alloy 20 is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. In addition, this super alloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.

 

There has long been a debate on whether Carpenter 20 is a stainless steel or a nickel alloy because the nickel content is right on the border of defining it as one way or the other. So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. Either way it is still great for corrosion resistance.


Characteristics:
  • Excellent general corrosion resistance to sulphuric acid
  • Excellent resistance to chloride stress corrosion cracking
  • Minimal carbide precipitation during welding
  • Excels in resisting corrosion to hot sulphuric acids

    ApplicationMachinery

    Mahesh Enterprises is India’s one of the leading Fasteners manufacturers & Suppliers in Monel K500. It is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of greater strength and hardness. These amplified properties, strength and hardness, are obtained by adding aluminum and titanium to the nickel-copper base and by a thermal processing used to effect precipitation, typically called age hardening or aging. When in the age-hardened condition, Monel K 500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K 500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400. Plus, it can be further strengthened by cold working prior to precipitation hardening. The strength of this nickel steel alloy is maintained to 1200° F but stays ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F.

     

    It is spark resistant and non-magnetic to -200° F. However, it is possible to develop a magnetic layer on the surface of the material during processing. Aluminum and copper may be selectively oxidized during heating, leaving a magnetic nickel rich film on the outside.


    Corrosion Resistant Monel K 500 :

    The corrosion resistance of alloy K 500 is substantially equivalent to that of alloy 400 except that when in the age hardened condition, nickel alloy K 500 has a greater tendency toward stress-corrosion cracking in some environments. Monel K 500 has been found to be resistant to a sour-gas environment. The combination of very low corrosion rates in high-velocity sear water and high strength make alloy K 500 particularly suitable for shafts of centrifugal pumps in marine service. In stagnant or slow-moving sea water, fouling may occur followed by pitting but this pitting slows down after a fairly rapid initial attack.


    Characteristics of Monel K500 :
    • Excellent resistance to high velocity sea water
    • Resistant to a sour-gas environment
    • Excellent mechanical properties from sub-zero temperatures up to about 480C
    • Non-magnetic alloy
    • Corrosion resistance in an extensive range of marine and chemical environments. From pure water to non-oxidizing mineral acids, salts and alkalis.

    Application:

    Sour-gas service applications

    • Oil and gas production safety lifts and valves
    • Oil-well tools and instruments like drill collars
    • Oil well industry
    • Doctor blades and scrapers
    • Chains, cables, springs, valve trim, fasteners for marine service
    • Pump shafts and impellers in marine service

    Mahesh Enterprises is India’s one of the leading Fasteners manufacturers & Suppliers in Inconel 600. It is a nickel-chromium alloy used for applications that require corrosion and high temperature resistance. It is designed for service temperatures from cryogenic to elevated temperatures in the range of 2000° F. It is non-magnetic, has excellent mechanical properties, and presents the desirable combination of high strength and good weld ability under a wide range of temperatures. The high nickel content in Inconel 600 enables it to retain considerable resistance under reducing conditions, makes it resistant to corrosion by a number of organic and inorganic compounds, gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions. Typical applications of this nickel alloy include the chemical, pulp and paper, aerospace, nuclear engineering and heat treating industries.

     

    It is spark resistant and non-magnetic to -200° F. However, it is possible to develop a magnetic layer on the surface of the material during processing. Aluminum and copper may be selectively oxidized during heating, leaving a magnetic nickel rich film on the outside.
