  • What is 904L Stainless Steel Flanges?

Large inventory of high quality 150 lb, 300 lb and 600 lb 904L Flanges in many types and sizes.

A Stainless Steel Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system in Petro and chemical industry. Stainless Steel Pipe Flanges also provides easy access for cleaning, inspection or modification. SS Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. All types except the Stainless Steel Lap Joint flange are provided with a raised flange face. Each Stainless Steel Flange according to ASME B16.5 has a number of standard dimensions.

We Specialise in Manufacturing Large Diameter and High Thickness ASTM B649 Stainless Steel 904L Flanges. All SS 904L Flanges are manufactured in India, with raw materials coming from reputed Mills in India and overseas. We are stockholder and supplier of 904L Stainless Steel Flanges, Stainless Steel Pipe Flanges, Stainless steel welding neck flanges, stainless steel slip on flanges, stainless steel socket weld flanges, stainless steel lap joint flanges, stainless steel threaded flanges and stainless steel blind flanges in a wide range sizes, surface treatment, and ASTM standards. UNS N08904 | WNR 1.4539 | Alloy 904L.

BS 4504 904L Flanges DN50 PN10 are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for 150# Stainless Steel 904L Flanges, the standard height is 1/16" for ANSI B16.9 Flanges under 400#. For SAE 904L Flanges of 400# and up, the standard AISI 904L Flanges raised face height is 1/4". SUS 904L Flanges in our stock include ANSI B16.5 SS 904L Flanges, ASME B16.47 Series "A" ASTM B649 UNS N08904 Flanges, ASME B16.47 Series "B" ASME SB649 UNS N08904 Flanges and Pressure Vessel 904L Flanges. We offer you DIN spec certified Flanges from rough B16.5 forgings, at a competitive cost.

We also carry a line of SS flanges and gaskets kits in a variety of materials including rubber, non-asbestos and Teflon.

  • What are PN10, PN16 and PN25 Standards Flanges

What are PN10, PN16 and PN25 Standards Flanges?

PN10, PN16, PN25 and PN40 specify both pressure class in bars of pressure, and metric Flanges dimensions (such as bolt circle diameter, hole size, bolt size etc) according to international flange standards such as ISO 7005-1 or DIN 2501 that use the metric system of measurements. Flanges produced to ANSI, AWWA, ASA, or old British standards that are dimensioned in inches will not mate up with metric flanges in general. It is good practice when specifying a PN flange standard to indicate the actual working pressure since it is a common occurrence that a specific PN, say PN16, flange drilling is required on a fitting or valve to match adjacent flanges, but the pressure requirement is less than PN16.

  • 904L Stainless Steel Flanges Possible Alternative Grades

904l Stainless Steel Flanges Equivalent Grades

Grade

Features of alternative grades of SS 904L

316L

A lower cost alternative, but with much lower corrosion resistance.

6Mo

A higher resistance to pitting and crevice corrosion is needed.

2205

A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.)

Super duplex

Higher corrosion resistance is needed, together with a higher strength than 904L.

The steel shall conform to the requirements as to chemical composition specified.
The material shall conform to the mechanical properties specified.

SUS 904L Flanges Heat Resistance

Grade 904L stainless steels Flanges offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.

AISI 904L Flanges Heat Treatment

Grade 904L stainless steels Flanges can be solution heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for hardening these grades.

SS 904L Flanges Fabrication

Grade 904L stainless steel Flanges are high purity steels with low sulphur content. They can be machined using any standard methods. These grades can be readily bent to a small radius under cold conditions. Although subsequent annealing is not required in most cases, it should be carried out when the fabrication is performed under severe stress corrosion cracking conditions.

904L Stainless Steel Flanges producing through Cold forming

904L stainless steel Flanges is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.

Stainless Steel 904L Flanges Machining

The cold work hardening rate of Alloy 904L Flanges makes it less machinable than 410 and 304 stainless steel Flanges.

904L Flanges Welding

Welding of grade 904L stainless steels Flanges can be performed using all conventional methods. This grade does not require pre-heat and post-weld heat treatments. Grade 904L Flanges can be subjected to hot cracking in constrained weldment. Grade 904L electrodes and rods are used for welding grade 904L steel Flanges according to AS 1554.6.

Alloy 904L Flanges Hot Forming

Working temperatures of 1562 – 2102°F (850 –1150°C) are recommended for hot working processes. It is important that the entire workpiece be quenched from temperatures above 2012°F (1100°C). In the event of partial heating or cooling below 2012°F (1100°C), or if the cooling has been too slow, hot working should always be followed by a solution anneal and quenching. 904L Flanges should be solution annealed at 1940 – 2084°F (1060 –1140°C).

904L Stainless Steel Flanges Applications & Usage:
