Hastelloy B2 Alloy DIN 17751 2.4617 ASTM B619 B622 B626 N10665 Alloy Seamless Tubes

   

Hastelloy B2 Alloy ASTM B619 B622 B626 N10665 DIN 17751 2.4617 Characteristics:

1. Control of iron and chromium content to a minimum to prevent the generation of β-phase Ni4Mo. 
2. Excellent corrosion resistance of restore environment. 
3. An excellent resist to concentration sulfuric acid medium and large number of non-oxidizing acid corrosion. 
4. A very good resistance of chloride reduction of stress corrosion cracking corrosion (SCC). 
5. Good corrosion resistance of various organic acids.

Hastelloy B2 Alloy Metallurgical Structure

Hastelloy B2 is the face-centered cubic lattice structure. By controlling the content of iron and chromium at the minimum to reduce the processing brittle, prevent Ni4Mo precipitation during 700-870 °C.

Hastelloy B2 Alloy Corrosion resistance

Ni-Mo alloy Hastelloy B2 ASTM B619 B622 B626 N10665 DIN 17751 2.4617, the carbon and silicon content is extremely low, reducing the HAZ carbon and other impurities  precipitation, so the weld has sufficient corrosion resistance. Alloy Hastelloy B2 N10655 DIN 17751 2.4617 in the reduction of medium with very good corrosion resistance, such as a various temperature and concentration of hydrochloric acid.

In the middle of the concentration of sulfuric acid solution (or contain a certain amount of chloride ions) also has very good corrosion resistance. At the same time can be used to acetic acid and phosphoric acid environment. Alloy material suitable only in the metallurgical structure and pure crystal structure in order to have the best corrosion resistance.

Hastelloy B2 Alloy Application

Alloy Hastelloy B2 ASTM B619 B622 B626 N10665 DIN 17751 2.4617 with a wide range of applications in the field of chemical, petrochemical, energy manufacturing and pollution control , particularly in the sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, and other industries.Hastelloy B2 ASTM B619 B622 B626 N10665 Nickel Alloy Chemical compostion:
