Hastlloy B2 Flange is an important part of any pipeline system and needs to be high-quality. UNS N10665 Flange is used most commonly on piping applications to allow or restrict the flow of fluids. Flanges are typically installed on pipes by welding, but there are options for threaded and lap joint flanges that do not require welding. Flange connections are made by drilling bolt holes at equally-spaced intervals that will align to a matching flange face. The two flange faces are then positioned together and held together with a series of bolts and nuts.

WERKSTOFF NR. 2.4617 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.
Alloy B2 has poor corrosion resistance to oxidizing environments, 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.

Hastelloy Flanges Manufacturing Process
Flanges are manufactured using three main techniques: casting, cutting from rolled plate material, or forging. No matter the technique, the basic flange production includes processing raw materials, then forming them to the appropriate specifications. Flanges are finished to meet the applicable standards for fit and seal, then flanges are packaged and shipped to the customer.
Forged flanges are manufactured by heating steel billets, slabs, or other metal stock, then compressing the material using a power hammer, press, or die to shape the flange from a solid state. This process develops a continuous grain flow for improved strength. After the flange is forged, it is machined and finished to the appropriate specifications. Forged flanges are often more resistant to wear, but the production cost is greater.
The Applications of Hastelloy B2 Flanges
Hastelloy B2 Flanges are sturdy, robust, ductile and precisely finished. Hastelloy B2 Flanges are required by industries where power generation is done, chemicals are used, petroleum industry, etc. These Flanges are very strong only keeping in mind that they should be used above 1000 Degree F as it may affect their ductility.
