Stainless Steel 347 Pipe Fittings Manufacturer, Supplier and Exporter in India
Mcneil Instruments is a leading manufacturer, supplier, stockist, and exporter of Stainless Steel 347 Pipe Fittings in India, delivering reliable and heat-resistant fittings for demanding industrial applications. Stainless Steel 347 is a niobium-stabilized austenitic stainless steel that provides excellent resistance to intergranular corrosion, making it ideal for high-temperature service.
These pipe fittings are especially suited for environments involving repeated heating and cooling cycles, such as in aerospace, chemical manufacturing, petroleum refining, and power generation. The stabilization with niobium prevents carbide precipitation during welding, ensuring structural integrity even after prolonged exposure to elevated temperatures. With superior creep strength and stress rupture properties, SS 347 Pipe Fittings outperform many other stainless grades in high-pressure and thermal systems.

Frequently Asked Questions – Stainless Steel 347 Pipe Fittings
What are Stainless Steel 347 Pipe Fittings? ?
Stainless Steel 347 Pipe Fittings are niobium-stabilized austenitic stainless steels designed to resist intergranular corrosion after welding and during prolonged exposure to high temperatures.
How is SS 347 different from SS 321?
Both are stabilized grades; however, SS 347 uses niobium instead of titanium, offering better stability and creep strength at higher temperatures.
What industries use SS 347 Pipe Fittings?
These fittings are widely used in chemical processing, power generation, refinery systems, exhaust manifolds, and aerospace equipment due to their thermal stability.
