Hastelloy B3 Hydrogen Alloy DIN Stainless Round Bar
Hastelloy B-3 is a nickel-molybdenum alloy with excellent resistance to pitting, corrosion and stress corrosion cracking, and its thermal stability is better than that of alloy B-2. In addition, this nickel-steel alloy is highly resistant to erosion of the blade line and heat-affected zone. Alloy B-3 can also withstand sulfuric acid, acetic acid, formic acid, phosphoric acid and other non-oxidizing media. In addition, this nickel alloy has excellent hydrochloric acid resistance at all concentrations and temperatures. The distinguishing feature of Hastelloy B-3 is its ability to maintain excellent ductility during transient exposure to intermediate temperatures. This type of exposure is commonly experienced during heat treatment associated with manufacturing.
Limiting factors of Hastelloy B-3
Alloy B-3 has poor corrosion resistance to oxidizing environments. Therefore, it is not recommended to use it in oxidizing media or where iron or copper salts are present, as they may cause rapid premature corrosion failure. These salts may be produced when hydrochloric acid comes into contact with iron and copper. Therefore, if this nickel-steel alloy is used with iron or copper pipes in a system containing hydrochloric acid, the presence of these salts may cause the alloy to fail prematurely.

Fabrication with Hastelloy B-3
Problems associated with fabrication of alloy B-2 components should be minimized with alloy B-3 due to its improved thermal stability. A low carbon content permits alloy B-3 to be used in the as-welded condition. Hastelloy B-3 has good overall forming and welding characteristics. This alloy can be forged or otherwise hot-worked, providing that it is held at 2250° F for a sufficient amount of time to bring the entire piece to temperature. Since it is a low carbon alloy, the use of lower hot finishing temperatures may be necessary to achieve grain size control. It may also be formed by cold working. Although it does work-harden somewhat rapidly, B-3 alloy components can be made using all common cold forming techniques. All common welding techniques may be used with alloy B-3, however, oxyacetylene and submerged arc welding processes are not recommended when the fabricated item is to be used in corrosive service.
