Specialist Manufacturers of 321H Welded/ERW/Large Diameter Stainless Steel Pipes in India – Largest Suppliers of Fabricated & Custom Size SS 321H Welded Pipes at Lowest Prices!

Metline is one of the biggest manufacturer and supplier of stainless steel 321H welded pipes in India, with daily sales of around 25-30 tons to customers across India and overseas. Our regular stock of products include SS 304/304L welded pipes, SS 316L welded pipes, SS 321/321H welded pipes, Duplex welded pipes, and SS 201 welded pipes in size range of 1/2″ NB to 24″. We also stock and manufacture stainless steel 321H welded pipes in OD size range from 1/4″ OD to 12″ OD in thickness upto 10mm.

Stainless steel electric resistance welded (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. SS ERW pipes are manufactured from Strip/Coils and can be manufactured upto 12” NB. For sizes from 6” NB to 36” NB, Metline can produce fabricated pipes, made from cut to size plates. The plates are first rolled and then 100% X-Ray welding is done. Since large diameter stainless steel 321H welded pipes cannot be made on a rolling mill, we produce such pipes by rolling cut to size plates and performing welding operations on them. All large diameter 321H welded stainless steel pipes, are produced as per ASTM A358 Class I to Class V specifications. Meanwhile, stainless steel 321H welded pipes in sizes from ½” to 12” (SCH 5, SCH 10, SCH 40) can be produced on rolling mill as per ASTM A312 specification.

Stainless steel 321H welded pipes are widely used in crude oil industry, chemical industry, petrochemical industry, construction industry, and food industry. In addition to SS 304 welded or fabricated pipes, we also manufacture and supply related fittings, bends, flanges and fasteners.

About 321H Stainless Steel

321H is the higher-carbon modification of stainless steel 321. In addition, 321H is stabilized by an addition of niobium to resist intergranular corrosion. It is also able to withstand higher temperatures than type 321, due to its elevated carbon levels. While 321H displays the same welding and forming characteristics of type 321, the metal cannot be hardened by heat treatment. It is utilized in situations where type 321 cannot withstand the high temperatures, typically those exceeding 1000° F. Type 321H displays better resistance against creep than both 321 and 304 stainless steels.

321H also shows resistance against acid corrosion in a variety of environments. Lower temperatures provide better resistance, but the metal is able to withstand up to a 10% acid solution, that has been diluted, at elevated temperatures. However, the metal shows very little resistance against chlorine or sulfuric solutions at any given temperature.

Given their similar composition and characteristics, it is possible for stainless steels 321 and 321H to become dually certified.
