Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Alloy Steel P91 Pipes, which have limited application and are not recommended for end milling, drilling or tapping. Sulphur chlorinated, water – based cutting fluids work successfully when machining Alloy Steel P91 Seamless Pipes. Does not respond to customary aging treatments, but strain aging at relatively low temperatures (700 Degree F – 1100 Degree F) can improve creep and rupture strength when these Alloy Steel P91 Welded Pipes is in service at temperatures under 1300 Degree F.

Alloy Steel P91 EFW Pipes is an austenitic alloy, where tensile and creep strength can be improved by cold working. Browse our vast selection of high temperature sheet stock of these Alloy Steel P91 ERW Pipes or get in touch with professional for a personalized quote on your next high temp sheet order. Like other nickel alloys, Alloy Steel P91 Round Pipes is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride – bearing solutions (a form of degradation to which the austenitic stainless steels are prone).

These Alloy Steel P91 Square Pipes may be machined using conventional techniques, but cobalt grades of high – speed steel or carbide tools combined with rigid machine setups are recommended, as are positive feeds. Annealed material tends to form long, stringy chips, where as Alloy Steel P91 Rectangular Pipes that has had a degree of cold work will machine more easily.
