Table of Content
Piyush Steel is the largest manufacturer, stockiest, supplier, and distributor of Stainless Steel 321H Pipes. Stainless Steel 321H Pipes is a stabilized austenitic stainless steel similar to Type 304 but with a titanium addition of at least five times the carbon content. Titanium addition in Stainless Steel 321H Pipes is made to reduce or eliminate chromium carbide precipitation - resulting from welding or exposure to high temperatures. Stainless Steel 321H Pipes are the basic austenitic 18 / 8 steel stabilized by titanium or niobium additions. Our SS 321H Pipes is a stabilized stainless steel which offers as its main advantage an excellent resistance to inter - granular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 Degree F to 1500 Degree FThese pipes are available in various sizes ranging from 1/8” NB to 30” NB, the ERW pipes are available from ½” NB to 24” NB and EFW pipes from 6” NB to 100” NB. The austenitic structure of these SS 321H pipes allows excellent toughness, even down to cryogenic temperatures.
These SS 321H Pipes are used in various industries such as Power Generation, Off-Shore Oil Drilling Companies, Petrochemicals, Gas Processing, Specialty Chemicals, Pharmaceuticals, Pharmaceutical Equipment, Chemical Equipment, Sea Water Equipment, Heat Exchangers, Condensers, and Pulp and Paper Industry. At Piyush Steel we also stock a wide range of Stainless Steel 321H pipes, for instance 321H Stainless Steel Seamless pipe, 321H Stainless Steel Welded pipe, and other stainless steel as per customer's requirement. We perform a number of tests on our pipes to ensure high standard quality. The tests conducted are eddy current testing, hydrostatic testing or ultrasonic examination, NDT and also chemical and physical property inspection. Some of the other tests are chemical analysis, Mechanical test, Rockwell hardness test, chemical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection and so on. Customer satisfaction is our top priority and we strive to meet the same. Our highly qualified team of professionals strive hard to meet our customers’ needs and have thus received acclamations.
