Hastelloy B2 Suppliers - Nickel Alloy B2 , Alloy B2 , UNS N010665Hastelloy B2 is a solid solution strengthened, nickel-molybdenum alloy, with significant resistance to reducing environments like hydrogen chloride gas, and sulfuric, acetic and phosphoric acids. Molybdenum is the primary alloying element which provides significant corrosion resistance to reducing environments.
This nickel steel alloy can be used in the as-welded condition because it resists the formation of grain-boundary carbide precipitates in the weld heat-affected zone.
Material Alloy B2 provides excellent resistance to hydrochloric acid at all concentrations and temperatures.
In additions, Hastelloy B2 has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack. Alloy B-2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids.
Chemical Composition of Nickel Alloy B2
Physical Properties of Hastelloy B2 :Density ; 9.22 g/cm³ (0.333 lb/in³)
Melting Points ; 1427°C (2600°F)
Hastelloy B2 is equivalent to the below specifications :Equivalent materials to Hastelloy B2 are:
Limiting Factors of Hastelloy B2Alloy B2 has poor corrosion resistance to oxidizingenvironments, therefore, it is not recommended for use in oxidizing media or in the presence of ferric or cupric salts because they may cause rapid premature corrosion failure. These salts may develop when hydrochloric acid comes in contact with iron and copper. Therefore, if this alloy is used in conjunction with iron or copper piping in a system containing hydrochloric acid, the presence of these salts could cause the alloy to fail prematurely. In addition, this nickel steel alloy should not be used at temperatures between 1000° F and 1600° F because of a reduction in the ductility in the alloy.
Applications of Hastelloy Alloy B2HASTELLOY(r) B-2 is mainly used in chemical process equipment.
