Our Hastelloy B2 Threaded Flanges (UNS N10665) should not be used at temperatures between 1000 Degree F and 1600 Degree F as the alloy forms secondary phases that could decrease the ductility of the material. These Hastelloy B2 Slip On Flanges can be machined using all the traditional machining methods. More than most other metals of similar chemistry, our Hastelloy B2 Spectacle Blind Flanges offers superior protection against powerful chemical corrosion and comes with one of the best high – temp strengths of any steel.

These Hastelloy B2 Weld Neck Flanges should not be used in oxidizing media or where oxidizing contaminants are available in reducing media. Meanwhile, our Hastelloy B2 Lap Joint Flanges are also being offered in customized sizes and shapes to our customers. The extremely low carbon and silicon content of these Hastelloy B2 Socket Weld Flanges reduces precipitation of carbides and other phases in the heat – affected zone of welds and ensures adequate corrosion resistance even in the welded condition.

Our Hastelloy B2 Ring Joint Type Flanges is not recommended for use in the presence of ferric or cupric salts as these salts may cause rapid corrosion failure. Ferric or cupric salts of these Hastelloy B2 Nippon Flanges may perhaps develop when hydrochloric acid comes in contact with iron or copper.
