What is Stainless Steel 347 Flanges?
The stainless steel 347 material can be used for a wide range of temperatures. The Stainless Steel 347 Flanges work equally well for high temperatures as well as cryogenic temperatures. They are ideal for use in applications that involve high wear and tear. The material is known for its outstanding capabilities for withstanding oxidation and wear. Due to its ability of withstanding extreme conditions and enhanced mechanical properties, the Stainless Steel 347 Flanges are widely used in heavy exhaust systems and boilers. These flanges are of the specification ASTM A182 and A240; they are forged and rolled. Also, according to the specification they are for high temperature and high pressure service applications. Stainless Steel 347 Flanges are also available under different standards, such as ASME, ANSI, EN, and DIN.
The Stainless Steel 347 Flanges are available in different types and various faces. The structure of the flange varies with the type and hence they are used for different purposes. The welding methods also change with the variation in faces, which impacts their characteristics. Their nominal diameters are within the range of ½” to 48”. They are also available with different pressure ratings, from classes 150 to 2500, and pressure number of PN6 through PN64.
The chemical composition of the Stainless Steel 347 material consists of 17% chromium, 9% nickel, carbon and several other elements in its composition. They come with a high melting point of 1454 degrees C, and that is why they can ideally be used in high temperature applications. The strength properties of the Stainless Steel 347 material is quite similar to that of the 304 grade. It possesses a min yield strength of 205 MPa, and min tensile strength of 515 MPa. Due to the unique characteristics of the material, the 347 grade is used in environments that have severe corrosive conditions, and hence they are widely used in the petroleum refining industries. Some of the common applications where SS 347 Flanges are widely used would be some chemical processes occurring in high temperature and heat exchanger tubes.
347H Stainless Steel Weld Neck Flange Vs ASTM A182 F347 Slip on Flanges
The 347H Stainless Steel Weld Neck Flange is mostly used for high temperature applications where the conditions are quite severe and critical. These flanges are capable of relocating stress to the pipes, which ensures that there is a decrease in high-stress concentration present at the bottom of the flange.
The ASTM A182 F347 Slip on Flanges are not capable of withstanding as critical situations as the 347H weld neck flanges. They are used for fluids that operate at lower pressure and they should also possess little risk of leakage. These flanges are slipped into the pipe before they are double welded from inside and outside to establish leakage proof connections.
How to weld SA 182 F347 Blind Flange?
The SA 182 F347 Blind Flange, just like any other standard flange, can be raised faced or flat faced. They are basically bolted instead of welding at the ends of the piping system or nozzle of the valve. This helps the blind flanges to easily uninstall at the time of pipe inspection or maintenance.
SS 347 Flange Vs ASTM A182 F347h Flanges
There are many differences between SS 347 Flange and ASTM A182 F347h Flanges. Firstly, they have a different chemical composition. The 347 grade contains no more than 0.08% carbon in its alloy, whereas the grade 347H contains carbon in its composition within the range of 0.04-0.10%. These materials also contain niobium, which gives them their unique characteristics. Due to the presence of higher carbon content, the 347H alloy demonstrates better high temperature and creep properties.

Heat treatment cannot harden 347 stainless steel Flanges; in fact, the only heat treatment operation conducted on it is annealing at roughly 1950oF (1065oC) followed by a water quench. This treatment provides the greatest corrosion resistance for type 347 forgings.

Shielded fusion and resistance welding processes can be used to fuse Type 347 Flanges. Austenitic stainless steel welds do not harden when cooled, hence the welds are robust.
Because of the likelihood of carbon pick up in the weld area, oxyacetylene welding is not suggested.
