UNS N10665 Hastelloy B2 Seamless Pipe

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.

Product Introduction

Hastelloy B2 Seamless Pipes (UNS N10665 Seamless Pipes) 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. Also referred as WNR 2.4617 Seamless Pipe, we provide these types of alloys in all material grades, specifications and sizes.

Properties of Hastelloy B2 Seamless Tubes:

Hastelloy B2 seamless tubes offer excellent resistance to various forms of corrosion, including stress corrosion cracking, pitting, and crevice corrosion. The tubes are highly durable and offer excellent strength to weight ratio, which makes them ideal for high-pressure applications. Hastelloy B2 seamless tubes also exhibit exceptional thermal stability, which makes them ideal for use in high-temperature environments.

Applications of Hastelloy B2 Seamless Pipes:

Hastelloy B2 seamless tubes are extensively used in the chemical processing industry for handling highly corrosive fluids such as hydrochloric acid and sulfuric acid. The tubes are also used in other industries such as food processing, pharmaceuticals, and wastewater treatment. Hastelloy B2 seamless tubes find application in heat exchangers, evaporators, columns, and reactors. They are also used in transfer piping for transferring corrosive fluids from one plant to another.
