Valour Alloys Inc., we carry a full inventory and Supply Stainless Steel 321h Flanges products in a variety of sizes widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.

Grade 321H is a modification of 321 with higher carbon content, to provide improved high-temperature strength. A limitation with 321 is that titanium does not transfer well across a high-temperature arc, so it is not recommended as a welding consumable.

321H flanges are a specific type of flange used in various industrial applications, primarily in high-temperature and high-pressure environments. These flanges are designed to work with pipes and other equipment made of 321H stainless steel, which is an austenitic stainless steel alloy known for its excellent high-temperature performance, corrosion resistance, and exceptional mechanical properties.

ISO 9001:2015, PED/27/EC and OHSAS 18001:2015 Approved Manufacturer of Stainless Steel 321H Flanges in Specification ASTM A182 321H and Types Like 321H Weldneck Flange, 321H Blind Flange, 321H Socketweld Flange, 321H Slip On Flange, 321H Threaded Flange, 321H Laped Joint Flange, 321H Screw Flange, 321H Plate Flange, 321H WNRF Flange, BLRF Flange, SWRF Flange, 321H SORF Flange etc.

Material Composition: 321h stainless steel is an austenitic stainless steel alloy, primarily composed of iron, chromium (17-19%), nickel (9-12%), and a small amount of titanium (at least five times the carbon content). The titanium addition is what distinguishes it from other stainless steel grades and provides superior resistance to carbide precipitation and sensitization.

Corrosion Resistance: 321h stainless steel is highly resistant to corrosion, particularly in high-temperature and high-stress environments. It offers excellent resistance to a wide range of chemicals, including acids and bases, making it suitable for various industrial applications.

High-Temperature Applications: 321h stainless steel flanges are often used in applications involving high temperatures, such as heat exchangers, exhaust systems, and combustion chambers. Its titanium content helps prevent intergranular corrosion, making it ideal for prolonged exposure to elevated temperatures.

Weldability: 321h stainless steel is known for its good weldability. It can be easily welded using common welding methods, making it a preferred choice in applications where welding is necessary.

Types of Flanges: 321h flanges come in various types, including slip-on flanges, weld neck flanges, blind flanges, threaded flanges, and socket weld flanges, among others. The choice of flange type depends on the specific requirements of the application.

321h stainless steel flanges are widely used in industries that require excellent corrosion resistance and high-temperature capabilities. Their unique composition, including the addition of titanium, provides superior performance in demanding applications, making them a reliable choice for various piping and equipment connections.
