Applications of nickel alloys for piping 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: Gal...Views -
Applications of nickel alloys for piping 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 -
How to use Hastelloy C276
The material is also sold under other names including Inconel C276.Hastelloy C276 is well known for its outstanding corrosion resistance in a wide range of extremely aggressive media and very punishing environments. It is truly a superal...Views -
How to use 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 -
How to use Incoloy 825
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 -
How to use Monel 400
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 -
Application of new anti-corrosion materials and technologies in military vehicles(2)
3 Application of anti-rust products such as anti-rust oilWhen military vehicles leave the factory, it is best to perform anti-rust treatment on the body and other parts. That is, in places where there is a lot of moisture and soil...Views -
Application of new anti-corrosion materials and technologies in military vehicles(1)
Most military vehicles have complex structures. In addition to steel and alloys, there are many non-metallic materials such as rubber and plastics. There are different degrees of corrosion and aging during storage and use. In addition, t...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(6)
4.3Effects of Oxygen-Induced Grain Boundary Embrittlement on Creep Properties In powder metallurgy, it is challenging to control the oxygen content of an alloy because alloy powders easily attract oxygen from the atmosphere. In nickel su...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(5)
4.2. Heat Treatment and Anisotropy Effects on Creep PropertiesFirst, we considered the grain morphology effect on creep properties. In the as-built condition, both HX and HX-a specimens exhibited columnar grain formation (Figure 5). Colu...Views -
Yttrium’s Effect on the Hot Cracking and Creep Properties of a Ni-Based Superalloy Built Up by Additive Manufacturing(4)
Figure 12 shows the microstructures of the vertical specimens along the loading direction after the creep test. The HX as-built specimen had large cracks (Figure 12a) along the horizontal grain boundary; these cracks merged and formed si...Views -
