Stainless Steel 321 Pipes & Steel 321 Tubes

Stainless Steel 321 Pipes & Stainless Steel 321 Tubes

Numax Steels is among renowned production house for 321 Stainless Steel Pipes & Tubes, which are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425 Degree C – 850 Degree C. A limitation by means of 321 Stainless Steel Pipes is that titanium doesn’t transfer well all over a high temperature arc, thus is not suggested as a welding usable.

321 Stainless Steel Tubes from Numax Steels is the grade of choice for applications in the temperature range of up to about 900 Degree C, combining resistance to scaling, phase stability and high strength with resistance to subsequent aqueous corrosion. Stainless Steel 321 Pipes Tubes is a heat resistant, titanium stabilized, austenitic alloy that's commonly used for service in the 1000 Degree F – 1600 Degree F temperature range.

SS 321 Pipes from Numax Steels is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800 Degree F – 1500 Degree F. SS 321 Tubes was developed for use in the chromium carbide precipitation range of 1800 Degree F – 1500 Degree F (427 Degree C – 816 Degree C) where un-stabilized alloys such as SS 304 are subject to intergranular attack. Alloy 321 Pipes from Numax Steels is similar to Alloy 304 but with a titanium addition of at least five times the carbon content. This titanium addition in Alloy 321 Tubes reduces or prevents carbide precipitation during welding and in the 800 Degree F – 1500 Degree F service conditions.
