Stainless Steel 904L pipes and tubes are available in both seamless and welded form in OD and NB sizes. In addition to standard sizes,

which are available in stock, our specialty is to manufacture and supply custom size SS 904L cold drawn seamless tubes from our factory.


Alloy 904L 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 904L is essentially non-magnetic in the annealed condition and can only be hardened by cold working. SS 904L seamless pipes 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 904L Pipes in different sizes, thickness and standards as per made to order requirements given by our customers. Stainless Steel Cold Drawn 904L Pipes is molybdenum demeanour austenitic stainless steel which is comparatively similar to SS 904L, but in the company of higher molybdenum substance.
