Specialist Manufacturers of 347H Welded/ERW/Large Diameter Stainless Steel Pipes in India – Largest Suppliers of Fabricated & Custom Size SS 347H Welded Pipes at Lowest Prices!

Metline is one of the biggest manufacturer and supplier of stainless steel 347H 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 347H 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 347H 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 347H welded stainless steel pipes, are produced as per ASTM A358 Class I to Class V specifications. Meanwhile, stainless steel 347H 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 347H 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 347H Stainless Steel

347H is another stainless steel in a class of metals labeled of precipitation-hardened steels. It possesses many of the same properties and characteristics of stainless steel 347. In addition to its higher carbon content, the alloy is stabilized with an addition of columbium, or sometimes tantalum. Both these properties allow 347H to be exposed to higher temperatures than both 347 and the 304 stainless steel grades can withstand. Because of its elevated resistance to corrosion, 347H is often applied in high stress, high corrosion environments where exposure tends to be severe. High temperature manufacturing, steam pipes, boiler tubes, chemical processes and steam servicing all benefit from 347H’s resilience. This resilience in turn is due to the potentially elevated levels of chromium in 347H’s composition. The metal can contain anywhere from 4-30%.

The metal displays high workability under most common welding techniques. It can be treated with heat, however, it will not respond. Only cold working is sufficient to increase 347H’s toughness and strength.
