Valour Alloys Inc., we carry a full inventory and Supply 321h Buttweld Pipe Fittings 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 is a high-temperature, austenitic stainless steel alloy that is commonly used in applications where elevated temperatures and resistance to corrosion are crucial. 321H pipe fittings are components designed to connect and modify the flow of fluids or gases in piping systems made from this specific alloy. These fittings play a vital role in various industries, including petrochemical, chemical processing, power generation, and more. Here's an introduction to 321H pipe fittings:

Material Composition: 321H pipe fittings are typically made from stainless steel grade 321H. This alloy is a modified version of 321 stainless steel, which contains titanium to stabilize the material against sensitization during high-temperature operations. The "H" in 321H stands for "High Carbon" content, which enhances its high-temperature properties.
High-Temperature Application: 321H pipe fittings are well-suited for applications that involve exposure to elevated temperatures. Their high-temperature resistance makes them ideal for use in industrial processes, such as furnace and boiler equipment, where consistent performance under extreme heat is required.
Corrosion Resistance: 321H stainless steel is highly resistant to corrosion, particularly in environments that contain sulfuric acid, as well as many organic and inorganic chemicals. This corrosion resistance is valuable in industries where corrosion can be a significant concern.
Weldability: 321H stainless steel, and consequently 321H pipe fittings, are known for their excellent weldability. They can be easily welded using various methods, making them a popular choice for constructing and modifying piping systems.
Versatile Applications: 321H pipe fittings are used in a wide range of applications, including chemical processing, oil and gas refining, power generation, aerospace, and heat exchangers, among others. They are especially valuable in environments where both high-temperature and corrosion-resistant properties are required.
Types of Fittings: 321H pipe fittings come in various types to suit different needs within a piping system. Common types include elbows, tees, reducers, couplings, flanges, and more. These fittings are designed to facilitate changes in pipe direction, size, and connection.
Compliance and Standards: Manufacturers of 321H pipe fittings adhere to industry standards and specifications to ensure the quality and performance of their products. These standards may include ASTM, ASME, and ANSI codes, among others.
321H pipe fittings are essential components in piping systems that require high-temperature resistance and corrosion resistance. These fittings are widely used in industries where reliability, durability, and performance under extreme conditions are of utmost importance. Their versatile applications and excellent weldability make them a preferred choice in many demanding environments.
