Hastelloy c276 round bar, compressive strength 750MPa, customizable, complete stock
C276 Hastelloy, also known as Inconel C276, is a high-performance nickel based alloy. It is mainly composed of elements such as nickel, molybdenum, chromium, and iron, and has excellent corrosion resistance and good mechanical properties. Therefore, it is widely used in various industrial fields under harsh environments.
Chemical composition is (%)
Mo | Cr | Fe | W | Co | C |
15.0-17.0 | 14.5-16.5 | 4.0-7.0 | 3.0-4.5 | ≤2.5 | ≤0.010 |
Si | Mn | V | P | S | Ni |
≤0.08 | ≤1.0 | ≤0.035 | ≤0.040 | ≤0.03 | belance |
The mechanical properties of Hastelloy alloy are very prominent, it has the characteristics of high strength and high toughness, so it has a certain difficulty in machining, when the deformation rate reaches 15%, it is about twice that of 18-8 stainless steel. Hastelloy also has a medium-temperature sensitization zone, and its sensitization tendency increases with the increase of deformation rate. When the temperature is high, Hastelloy is easy to absorb harmful elements, which reduces its mechanical properties and corrosion resistance.
C-276 Hastelloy alloy belongs to the nickel-molybdenum-chromium-iron-tungsten nickel-based alloy, which is the most corrosion-resistant one among modern metal materials. It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low-temperature and medium-temperature hydrochloric acid. Therefore, in the past thirty years, it has been widely used in harsh corrosive environments such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and papermaking, environmental protection and other industrial fields.
The various corrosion data of Hastelloy C-276 alloy are typical,
but they cannot be used as specifications, especially in unknown
environments. Materials must be selected after testing. Hastelloy
C-276 alloy does not contain enough Cr to resist corrosion in
strong oxidizing environments, such as hot concentrated nitric
acid. This alloy is mainly produced for chemical process
environments, especially in the presence of mixed acids, such as
the discharge pipe of the flue gas desulfurization system.
The mechanical properties of Hastelloy alloy are very outstanding.
It has the characteristics of high strength and high toughness, so
it is difficult to machine. When the deformation rate reaches 15%,
it is about twice that of 18-8 stainless steel. Hastelloy alloy
also has a medium-temperature sensitization zone, and its
sensitization tendency increases with the increase of deformation
rate. When the temperature is high, Hastelloy alloy easily absorbs
harmful elements, which reduces its mechanical properties and
corrosion resistance.
