There are several brands, quality, and grade of products available in the market but when it comes to choosing the right quality and grade people often choose ss 904l pipe-fittings-flanges-forged. These are one of the best qualities and ss 904l grade products that is manufactured using best and premium quality of the tested raw material. The raw material is well tested and inspected with national and international quality standard. These pipe fittings, flanges, and forged products are available in different shapes and sizes as per the demand and requirement of customers. Furthermore, manufacturer conducts various tests and inspection like 100% radiography test to prove products quality.

These products are even available in larger to a smaller diameter as well as sizes. Grade 904l is also known as UNS N08904 stainless steel that is a low carbon and nickel and chromium steel that is a mixture of copper and molybdenum. Products that are made using 904l grade are considered best due to its high tensile strength, corrosion resistance, and durability. Well, if we talk about ss 904l pipe-fittings-flanges-forged specification these products include ASTM A182, ASME SA182 & SA403 specification as well. These products are also available in seamless, fabricated and welded types with 904l variants. These pipe fittings, flanges and forged have a radius of 1D to 10D and custom as well.

If you buy these pipe fittings, flange and forged from a reputable manufacturer you will get these products in varied ranges, shapes, and sizes as per your demand and requirement. The normal size of these products ranges from ½ NB to 48 NB and all sizes are scheduled into various sections like SCH10, SCH49 & SCH160. Moreover, if we talk about the dimensions that they are in accordance with ANSI/ASME B16.9, B16.28 & MSS-SP-43 standard.

UNS NO8904, commonly known as 904L stainless steel, is a low carbon austenitic nickel-chromium stainless steel with additions of molybdenum and copper. 904L pipe fittings, 904L flanges and 904L product forms are mainly used where the corrosion resistant properties of 316L and 317L are inadequate, especially in severe corrosive conditions.

Due to the combination of high contents of chromium, nickel, molybdenum and copper, stainless steel 904L pipe fittings and 904L flanges exhibit greater resistance to pitting and crevice corrosion and to general corrosion in reducing acids.

When compared to 2205 grade duplex stainless steel, 904L has similar corrosion resistant properties but lower mechanical strength. 2205 is also a lower cost option compared to 904L, but is not suitable for temperatures above 300°C. Overall among the three grades i.e. 904L, 316L and 2205, 316L stainless steel is the lowest cost option, but offers comparatively lower corrosion resistance.

Stainless steel 904L fittings, and 904L flanges are widely used for manufacturing tanks, vessels, piping, heat exchangers, and other equipment used for handling sulphuric, phosphoric and acetic acids, bleaching operations in the pulp and paper industry. In addition, 904L tube and 904L pipe fittings are widely used for general piping requirements in the oil and gas, chemical and pharmaceutical industries.

Sanghvi Impex also stocks and supplies a complete range of SS 904L seamless pipes to complement our existing production range of SS 904L buttweld fittings and SS 904L flanges. Stainless steel 904L pipes can be supplied in cut to length sizes and also machined or fabricated to meet your custom piping requirements.
