A few days back, my uncle called me and told that he faced a major setback due to the lack of high-grade material that is imperative for his industry’s functioning at extreme conditions and also, that his dealers/clients were not happy with his industrial performance. And that was the time, when I began my search regarding what my uncle wanted. Soon, I discovered Hastelloy Round Bar that suits the best for my uncle’s issue. If you’re too looking for superalloy with high temperature strength and impact resistance, then this 3-minute-read blog is perfect for you.
Overview of Hastelloy Round Bar
This is a type of special type of superalloy that has high temperature strength and features numbers of outstanding properties which make it highly efficient, reliable and number-1 choice for most of the type of applications working at extreme temperature where other metals would simply surrender. High temperature strength of this superalloy is development through methods like precipitation strengthening and solid solution strengthening.
It is a strong nickel-molybdenum-chromium with tungsten content which makes it highly resistant to corrosion, oxidation, crevice corrosion cracking and pitting. Nevertheless, its low carbon content makes it insensitive to the development of grain-boundary carbide precipitation in the heat affected welding area and helps to maintain resistance against corrosion.
The surface of Hastelloy Round Bar is treated in order to increase its durability, functionability and stability when working at extreme conditions like high temperature and high pressure. Such surface treatments include bright polished, rough turned, matt finish, sand blasting, and some others. It comes in different sizes that varies between 5 mm to 500 mm, diameter ranging between 0.1 mm to 500 mm, and length ranging between 100 mm to 6,000 mm and even more. However, their specification can also vary, as well as, customization is also available.
Special Properties
- Density - 8.89 g/cm3
- Melting Point - 1370 °C (2500 °F)
- Tensile Strength Psi – 1,15,000 (MPa – 790)
- Yield Strength (0.2%Offset) Psi – 52,000 (MPa – 355)
- Elongation - 40 %
Uses of Hastelloy Round Bar
This type of round bar is usually used to make different parts such as flywheels, axles, shafts and gears for rotating machinery applications. It is also used for manufacturing tubing, seamless pipes and other equipment for extensive range of applications such as gas turbine, aerospace, oil drilling, industrial furnace applications, geothermal, oil and gas industry, chemical processing industries, corrosive systems, pharmaceuticals, waste treatment plants, etc.
Due to its such overwhelming properties, it also finds its usage in other fields like food processing equipment, condensers, heat exchanger, boilers, petroleum refineries, cooling towers, steam exhausts, electric generation plants, solar energy, pulp and paper production, pollution control stack liners etc.
Benefits of Hastelloy Round Bar
According to the shreds of information I tried to put forth simply depicts that this superalloy is widely used for manufacturing various types of equipment which are resistant to high temperature, high pressure, stress cracking and localized corrosion. Its other offered benefits include:
- Oxidation resistant up to 2200-degree F (1200-degree C)
- Resistance to nitriding and carburization
- Highly resistant to stress corrosion cracking and uniform attack
- Ease of fabrication and welding
- Outstanding localized corrosion resistance
As soon as I summoned all these pieces of information about Hastelloy Round Bar, I contacted my uncle and conveyed him this so that he himself can go through its properties, specifications and benefits. And, yesterday he thanked me and said his clients are happy now and inked several contracts. Hope, you also find this helpful.
