347/347H stainless steel is type of common austenitic stainless steels such as 304, 316 and 321 and is widely used in elevated temperature applications. Stainless steel 347 has excellent forming and welding qualities, and the addition of columbium and tantalum helps for exceptional intergranular corrosion resistance.

Alloy 347H is the higher carbon variant of the alloy, enabling enhanced creep resistance and for higher strength at temperatures above 537°C. Grade 347 is similar to grade 321, but with slightly improved corrosion resistance in strongly oxidizing environments. Stainless steel 347 is essentially non-magnetic in the annealed condition and can only be hardened by cold working. SS 347/347H seamless Tubes are popularly used in petroleum refineries, aircraft engine components, power generation, heat exchangers, pressure vessels, welded fabrications and other high heat applications.

We also offer SS 347/347H Tubes in different sizes, thickness and standards as per made to order requirements given by our customers. Stainless Steel Cold Drawn 321/321H Tubes is molybdenum demeanour austenitic stainless steel which is comparatively similar to SS 321/321H, but in the company of higher molybdenum substance. SS 321/321H Tubes can be supplied in cut-to length sizes and as well fabricated or machined to meet up your customized piping requirements.

We can help supply all of the Stainless Steel ASTM 347/347H Seamless Tubes for use in the oil or natural gas industries. Seamless Tubes / Welded Tubes of premium quality is supplied by KOBSINDIA, per ASTM A 213, ASTM A 269 and ASTM A 511. Not only we stock standard sizes and grades of Seamless tubes in Stainless Steel SS304 & SS316, but we also do maintain huge inventories of Alloy Steel based pipes in 304H, 309/S, 310/S, 317/L, 321H, 347H, Alloy 20, Duplex 2205, Duplex 2507, Alloy 200/201, C276, Alloy 400, Alloy 600, Alloy 625, Alloy 800H, Alloy 800HT, 254SMO, AL6XN and others. Stainless Steel ASTM 304H Seamless Tubes, the Tubes shall be suitable for bending, flanging, and similar forming operations, and for fusion welding.
