Hastelloy is a kind of nickel based alloy. Hastelloy Alloy can be divided into two groups; one contains more molybdenum and the other contains more chromium. They all have excellent resistance to strong oxidizing solutions and high durability in reducing agents. Because of the low carbon content and less carbide precipitation during welding, they also have the ability to resist intergranular corrosion.

Description of Hastelloy Alloy
Hastelloy metal is a kind of nickel based alloy. Hastelloy Alloy can be divided into two groups; one contains more molybdenum and the other contains more chromium. They all have excellent resistance to strong oxidizing solutions and high durability in reducing agents. Because of the low carbon content and less carbide precipitation during welding, they also have the ability to resist intergranular corrosion.
Hastelloy metal is mainly used in the metal industry, rather than in the full form of nickel-chromium-molybdenum alloys. Hastelloy Alloy components include molybdenum, chromium, iron, tungsten, cobalt, manganese, copper, vanadium, phosphorus, silicon, and sulfur.
According to the grade and standard of the alloy, the composition is different. Each of these categories and levels has specific characteristics and applications. Hastelloy suppliers also sell all different grades of products. The products range sheet, coil, strip, wire, bar, etc. In addition to Hastelloy Metal, under the superalloy series, many grades include Inconel Alloys and Monel Alloys.
Huaxiao has been engaged in metal export for more than ten years. It has a professional export operation team, a professional production and inspection team, etc. In addition to the product rules we show, we can also provide professional customized services.

Hastelloy C 276 Alloys
Hastelloy C 276 alloy is a nickel-chromium-molybdenum alloy containing tungsten with extremely low silicon-carbon content and is considered a universal anti-corrosion alloy. 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 and medium temperature hydrochloric acid.
Therefore, in the past 30 years, in harsh corrosive environments, such as the chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper, environmental protection, and other industrial fields, it has been widely used.

Differences between Hastelloy C276 and Hastelloy C22
Hastelloy C276 (N10276) and C22 (N06022) In simple terms, the similarities and differences of the alloys are roughly similar and slightly different.
First, let’s take a look at the difference between the two materials:
C276 main components: 57NI-16MO-16CR-5FE-4W-2.5CO-1MN-0.35V-0.08SI-0.01C
C22 main components: 56NI-13MO-22CR-3FE-3W-2.5CO-0.5MN-0.35V-0.08SI-0.01C
It can be seen from the above that the main elements are not very different, especially in the context of NI, FE, and CO, Mo and Cr are slightly different.
C22 is more resistant to local corrosion than 276, which can be understood as an upgraded version of 276.
In addition, Special Steel 100 Seconds also lists the difference between the two types of solder:
C276 welding material is welding wire ERnicrmo-4, welding rod Enicrmo-4
C22 welding material is welding wire ERnicrmo-10, welding rod Enicrmo-10
1. In terms of the difficulty of purchasing: C276 is easier to buy in the spot market, with complete specifications, and C22 has only one or two alloy stockists.
2. In terms of use: C22 is better, but in general, both can be used in most working conditions.
3. In terms of material cost: the main components are not very different and should be calculated according to the cost. The density of C22 alloy (8.7) is lower than that of C276 alloy (8.9), which should be higher than that of C276. However, due to the lower cost, C22 cannot form a mass production supply, and the cost is higher than that of C276.
