Stainless Steel 347 Flanges

PDO Approved Manufacturer of SS 347 Lap Joint Flange, 347 Stainless Steel RTJ Flange

Stainless Steel 347 Flanges are used at cryogenic temperatures as well as high temperatures and at high wear and tear applications. The material can withstand oxidation and wear very well. The Stainless Steel 347 Flanges are used in boilers and heavy exhaust systems due to the excellent mechanical properties. The flanges come in ASTM A182 and A240 specifications. These are forged, rolled and high temperature service applications and high pressure service applications by specification. These flanges also come under the ANSI, ASME, BS, DIN and EN standards.

Stainless steel 347 Pipe Flanges, ANSI B16.5 SS F347 Screwed Flanges, Check 150# ANSI SS 347 Plate Flange Specification

The SS 347 Lap Joint Flange and other types of this grade of material are made in ½ inches through 48 inches nominal diameters. The flanges also come with different pressure ratings as classes 150 through 2500 and PN6 through PN64. There are different types according the faces such as flat face, raised face and ring type joint. The 347 Stainless Steel RTJ Flange is the ring type joint flange which comes in two halves and each half gets welded onto different pipe ends before making the connection. The material can also come in a high carbon variation 347H which has more toughness.


The 347 grade is made up of 17% chromium, 9% nickel and carbon, manganese, silicon, phosphorus, sulfur, cobalt and iron in the composition. The ANSI B16.5 Stainless steel 347 Pipe Flanges have high melting point of 1454 degrees Celsius. The material also has similar strength properties to the 304 grade. The minimum yield strength is 205MPa and the minimum tensile strength is 515MPa. There are different types of flanges used for different application requirements. The SS UNS S34700 Weld Neck Flange has a neck welded to it so that the pipes could be connected easily into the welded neck. Navstar Steel is a leading supplier and manufacturer of these flanges in all scales and grades. Please feel free to contact us for more information on the flanges and prices.
