Product Introduction

UNS N10665 seamless pipe is made from Hastelloy B2, a nickel-molybdenum alloy that is known for its excellent resistance to corrosion in reducing environments. This type of pipe is widely used in chemical processing, aviation, electronics, and other industrial applications where there is a risk of corrosive attack.

Hastelloy B2 is a solid solution strengthened, nickel-molybdenum alloy that contains significant amounts of molybdenum, which provides it with its corrosion resistance. It 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 makes it a popular choice for applications where there is a risk of corrosion from acids such as hydrochloric acid, sulfuric acid, acetic acid, and phosphoric acid.
