Shubham Metals is a leading Stainless Steel 347H Buttweld Fittings Manufacturers in Bangalore, India , which provides piping parts that are designed to operate under high temperature conditions and with high corrosion resisting capabilities. SS 347H is an austenitic stainless steel with a fine level of mechanical strength and very high resistance to intergranular corrosion, and is an alloy with a high content of niobium which also serves to stabilize it. These fittings in particular are designed to operate in the long-term under thermal loads, allowing them to withstand structural integrity in highly-stressful pipelines in the industrial environment in high temperature up to 925°C (1700°F).
Our SS 347H Buttweld Fittings are made to ASTM A403 WP347H, ASME B16.9/B16.28, and MSS-SP-43 standards requirements and ensure dimensional accuracy, weldability and long-term reliability. These elements can be used in boilers, superheaters, petrochemical units, refineries, and high temperature, high pressure chemical processing systems, where the operational safety and high efficiency of the process is critical.

Why Stainless Steel 347H? – High-Temperature and Corrosion Resistance
S.S 347 H is a modified SS 347. The major discrepancy is that it is much more carbon-rich (0.04-0.10%), and hence it enhances creep strength and thermal endurance during high-temperature work. Moreover, the niobium stabilization inhibits the sensitization and the formation of chromium carbide in the welding process so that the welded portions have corrosion resistance to continued intergranular corrosion during extended service processes.
The combination of these characteristics makes SS 347H the perfect choice in pipelines, heat exchangers, superheaters, and boilers in which thermal cycling and high operating temperature conditions require materials with high structural and oxidation resistance. SS 347H has better creep resistance and higher life under sustained thermal loading conditions than SS 304 or SS 316, and is therefore used in continuous high temperature conditions.
Key advantages of SS 347H include:
- High creep and tensile strength in high temperature.
- Intergranular welded pipeline corrosion resistance.
- Better oxidation and high temperature corrosion resistance.
- Through thermal cycling maintained mechanical properties.
- Reliability of vital systems in the industry.

Manufacturing Excellence – Ensuring Thermal Reliability
All SS 347H Buttweld Fitting is a rigorously manufactured product that is supposed to deliver high temperature performance, corrosion and compatibility with weld.
Process of Production Entails:
- Raw Material Check: Checking the chemical composition and traceability of certified niobium-stabilized stainless steel plate or pipes of certified mills is performed.
- Construction Operations: The fittings are shaped by hot forming, cold forming or hydraulic pressing depending on pressure and size.
- Beveling & Trimming: Removes all imperfections in the weld and provides a uniform thickness of the walls to meet the requirements of a high pressure service.
- Surface Finishing: Eliminates defects and gives the surfaces smooth welding material.
- Inspection & Traceability: Wall checks, dimensional inspection, surface inspection and heat numbering ensure that the industry standards are met.
Such strict production is done by making sure that every fitting will withstand thermal stress, pressure variations and corrosive conditions to achieve a long service.
