Chinese Professional Nickel Welding Wire - Hastelloy B-2/B-3 Manufacture – Sekonic Detail:

Common Trade Names: Hastelloy B-2,NS3202,UNS N10665,NiMo28, W.Nr.2.467,NiMo28

Hastelloy 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. This nickel alloy 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 B2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids.

Why Hastelloy B-2 ?

Alloy B-2 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.

• Excellent corrosion resistance for reductive environment.

• Excellent resistance to sulfuric acid (except for concentrated) and other non-oxidizing acids.

• Good resistance to stress corrosion cracking (SCC) caused by chlorides.

• Excellent resistance to corrosion caused by organic acids. 

• Good corrosion resistance even for welding heat affect zone due to low concentration of carbon and silicon.

Hastelloy B-2 Application field:

Widely used in the chemical, petrochemical, energy manufacturing and pollution control related processing and equipment ,
especially in the processes dealing with various acids (sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid
and so on
