Hastelloy C276 Hastelloy alloy plate N10276 flat cold rolled sheet
NS334 hot rolled medium and thick plate.
The corresponding grades of C276 plates are mainly NS3304,
00Cr15Ni60Mo16W5Fe5 (or 00Cr16Ni60Mo16W4), etc. C276 alloy, also
known as Hastelloy C-276 (Hastelloy C276), is a tungsten-containing
nickel-chromium-molybdenum alloy. It is widely used in various
harsh corrosive environments due to its excellent corrosion
resistance.
Excellent oxidation resistance up to 1200°C
Good high temperature strength
Hastelloy C-276 is a nickel-chromium-molybdenum alloy containing
tungsten, very low silicon carbon content, and is considered a
universal corrosion resistant alloy
In the state of oxidation and reduction, it has excellent corrosion
resistance to most corrosive media.
Has excellent resistance to pitting, crevice corrosion and stress
cracking corrosion.
Alloy c-276 is a nickel-chromium-molybdenum alloy containing tungsten and extremely low carbon
and
Alloy c-276 is characterised by:
1.excellent resistance to a wide range of corrosive media,under oxidizing and reducing conditions
2.excellent resistance to pitting, crevice corrosion,
The main components and contents of C276 plate are as follows:
Nickel (Ni): 57-59%
Molybdenum (Mo): 15-17%
Chromium (Cr): 14.5-16.5%
Iron (Fe): 4-7%
Cobalt (Co): small amount
Copper (Cu): A small amount
Niobium (Nb): small amount
Aluminum (Al): A small amount
Silicon (Si): Trace amount
Carbon (C): Trace amount
| Ni | Mo | Cr | Fe | Co | Cu | Nb | Al | Si | C |
| 57-59% | 15-17% | 14.5-16.5% | 4-7% | small amount | small amount | small amount | small amount | Trace amount | Trace amount |
These ingredients give C276 plate excellent corrosion resistance
and oxidation resistance. For example, the nickel content is as
high as 57-59%, which significantly improves the stability of the
alloy in various corrosive environments; the molybdenum content is
between 15-17%, which enhances its pitting corrosion resistance and
resistance in acidic media. Resistance to stress corrosion
In addition, C276 plate also has good mechanical properties, with a
tensile strength of 725-965MPa, a yield strength of 415-565MPa, and
an elongation of 45-55%.
Application areas
Due to its excellent corrosion resistance and mechanical
properties, C276 sheet is widely used in several industries:
Chemical and petrochemical industry: used to manufacture
components and catalytic systems that come into contact with
chloride-containing organic matter, as well as equipment such as
oil tanks, oil well pipelines, reactors, and storage tanks
Marine Engineering: Suitable for seawater corrosive environment,
resistant to erosion by wet chlorine, various oxidizing chlorides,
chloride salt solutions and other highly corrosive media
Pharmaceutical and food processing: used to manufacture medical
devices and food processing equipment to ensure stable operation in
highly corrosive media
Pollution control equipment: such as filters, flue gas
desulfurization equipment, etc., utilizing their anti-oxidation and
anti-corrosion properties
This alloy has excellent corrosion resistance to most corrosive
media in both oxidized and reduced states. Excellent resistance to
pitting corrosion, crevice corrosion and stress corrosion cracking.
The alloy is suitable for use in a variety of chemical process
industries containing oxidizing and reducing media. The higher
molybdenum and chromium content makes the alloy resistant to
corrosion by chloride ions, and the tungsten element further
improves its corrosion resistance. Hastelloy C-276 is one of the
only materials that is resistant to corrosion by moist chlorine,
hypochlorite and chlorine dioxide solutions. The alloy has
significant corrosion resistance to high-concentration chloride
salt solutions (such as chlorine iron and copper chloride).
