Stainless Steel 304H Buttweld Fittings are one of the most commonly used fittings in high-temperature and high-pressure industrial applications. Known for their superior strength, heat resistance, and corrosion protection, these fittings are made from Austenitic Stainless Steel Grade 304H, which contains a higher carbon content than standard 304. This extra carbon provides enhanced mechanical strength and durability, making it perfect for environments where elevated temperature performance is crucial.
We are a leading Stainless Steel 304H Pipe Fittings Manufacturer in India, offering a wide range of buttweld fittings that meet ASTM A403 / ASME SA403 WP304H standards. Our fittings are designed to ensure leak-proof joints, long service life, and easy installation in pipelines that transport gases, liquids, or other media.
What are Stainless Steel 304H Buttweld Fittings?
Stainless Steel 304H Buttweld Fittings are pipe fittings that are welded to the ends of pipes to create a continuous, leak-proof piping system. These fittings include elbows, tees, reducers, caps, and other components that help in changing the direction, branching, or diameter of the pipe system.
Grade 304H is a high-carbon variant of 304 stainless steel. The higher carbon content (0.04–0. 10%) improves its high-temperature strength and resistance to sensitization. This makes SS 304H Buttweld Fittings ideal for applications in industries such as power generation, heat exchangers, boilers, oil refineries, and chemical plants.

Types of Stainless Steel 304H Buttweld Fittings
We manufacture and supply a comprehensive range of ASTM A403 WP304H Stainless Steel Buttweld Pipe Fittings, each designed for specific purposes within a pipeline system. Below are some of the main types available in our stock:
➤ SS 304H Elbow
SS 304H Elbows are used to change the direction of the flow in a pipeline—available in 45°, 90°, and 180° bends. As a trusted SS 304H Elbow Dealer in India, we supply both seamless and welded elbows that offer excellent mechanical strength and corrosion resistance.
➤ Stainless Steel 304H Tee
A Stainless Steel WP304H Tee is used to combine or divide fluid flow. Available in equal and unequal types, these fittings are essential in industrial piping systems that require multiple branch connections. We are a stockholder of Stainless Steel WP304H Tee in various sizes and pressure ratings.
➤ ANSI B16.9 Stainless Steel 304H Reducer
Reducers are used to connect pipes of different diameters. The ANSI B16.9 Stainless Steel 304H Reducer comes in both concentric and eccentric forms. These fittings ensure smooth fluid flow transition while minimizing pressure loss.
➤ SS 304H Pipe Cap
A Pipe Cap is used to seal the end of a pipe, protecting it from contaminants and mechanical damage. As a Best Price of 304H SS Pipe Cap Exporter, we ensure precise manufacturing and quality testing to maintain international standards.
➤ Stainless Steel 304H Stub End
Stub Ends are used with lap joint flanges and are ideal for systems requiring frequent disassembly for cleaning or inspection. These are available in both short and long pattern dimensions.
➤ SS 304H Cross
Stainless Steel Cross Fittings are used when four pipes need to be connected at one point. These fittings are suitable for complex pipeline configurations where balanced flow distribution is required.
Features and Advantages of SS 304h Pipe Fittings
- High Temperature Resistance: The higher carbon content allows Stainless Steel 304H Butt weld Pipe Fittings to perform efficiently at elevated temperatures (up to 870°C).
