Material application of pipes and valves(2)
The external grooves such as those located on the Ring Type Joint (RTJ) faces of valve body flanges in carbon steel material are overlaid with Inconel 625 to avoid external crevice corrosion in offshore projects.Galling and friction:Gall...Views -
Material application of pipes and valves(1)
Nickel alloys, which are alloys with nickel as the principal element, maybe used for piping as well as different parts of industrial valves such as body, bonnet, ball, seat, stem, bolting, spring, etc.Valves are parts of piping systems a...Views -
Hastelloy™C-276
Hastelloy™C-276is well known for its outstanding corrosion resistance in a wide range of extremely aggressive media and very punishing environments. It is truly a superalloy amongst the high nickel-chromium-molybdenum materials, and is ...Views -
Inconel™625
This is one of several high nickel chromium alloys of particular mention because of its combination of very high strength, excellent fabricability, and outstanding corrosion resistance. It also has a particularly useful temperature range...Views -
Incoloy™ 825 alloy
Sometimes described as a super austenitic stainless steel, 825 is a long service forerunner of the nickel iron chromium alloys. With the addition of molybdenum, copper and titanium, this alloy will give excellent corrosion resistance to ...Views -
Monel™400 alloy
Introduced an 1905 Monel was the pioneer of the nickel based alloys offering high strength and good corrosion resistance. Its toughness and good wear properties made it very popular with pump and valve manufacturers. Although over shadow...Views -
Centrifugal Metallothermic SHS of Cast Co–Cr–Fe–Ni–Mn–(Х) Alloys (5)
Their combination, location, and morphology depend on the amount of Ti–Si–B (C) additive. In the case of low additive concentration (Fig. 7), the equiaxed precipitates of the phase enriched with chromium and silicon and fine individual...Views -
Centrifugal Metallothermic SHS of Cast Co–Cr–Fe–Ni–Mn–(Х) Alloys (4)
The analysis of structural constituents of the obtained alloys showed that these HEAs consist of two phases: a solid solution based on γ/α-Fe and a solid solution based on β-phase (NiAl intermetallic compound).The size of structural c...Views -
Centrifugal Metallothermic SHS of Cast Co–Cr–Fe–Ni–Mn–(Х) Alloys (3)
The metallothermic SHS of cast CoCrFeNiMn alloys in conditions of artificial gravity was described in detail in [32].SHS-produced cast alloys were characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and...Views -
Centrifugal Metallothermic SHS of Cast Co–Cr–Fe–Ni–Mn–(Х) Alloys (2)
The most widely studied HEAs are Co–Cr–Fe– Ni–Mn systems. These equiatomic alloys are represented by a disordered fcc solid-solution structure [3], which makes them attractive for research. It is common knowledge also that the fcc st...Views -
Centrifugal Metallothermic SHS of Cast Co–Cr–Fe–Ni–Mn–(Х) Alloys (1)
Abstract-A relatively new approach to obtaining metal materials containing several principal elements in equiatomic concentrations which look promising for replacing commercially used alloys is proposed. Such materials are called high-en...Views -
High-throughput nanoindentation mapping of cast Inconel™718 nickelbased superalloy: influence of the Nb concentration(4)
In fact, the hardness maps (Fig. 5a, b and c) reveal a direct correlation with the Nb content (Fig. 3s, t and u) and the temper condition. The histogram of hardness values in Fig. 6b show an average hardness of 4.7, 7.8 and 6.2 GPa for t...Views
