Stainless Steel 904L Pipe
Get In Touch
AISI 904L Pipe & UNS N08904 Seamless Pipe Manufacturer, Supplier & Exporter in India
Nishra Overseas is a leading manufacturer, supplier and exporter of Stainless Steel 904L Pipe in India. 904L is a non-stabilized austenitic steel with low carbon concentration and high concentrations of nickel and molybdenum, along with traces of copper. This composition gives it high resistance to reducing acids and general corrosion, along with strong resistance to cracking and carburization. The Stainless Steel 904L Pipe is available in nominal sizes from 1/8" to 24" NB and outer diameters up to 914.4mm, in lengths up to 30 meters, across multiple schedules and shapes.
As a trusted 904L Pipe manufacturer and supplier, we hold density-graded material to 7.95 g/cm³ manufactured to international and national standards, with a melting point of approximately 1350°C. 904L Tubing is widely specified where the corrosion resistance of 316L and 317L is no longer sufficient — making it the standard choice in aerospace, petrochemical, and pharmaceutical industries. We are among the leading 904L Stainless Steel Pipe manufacturers, suppliers and exporters in India, with our goal being to deliver the best quality products at the most reasonable rates, from Mumbai to clients across India and worldwide.
Stainless Steel 904L Pipe — Product Range
As a full-scale 904L Pipe manufacturer and exporter, our product range covers seamless, welded and ERW forms:
- SS 904L Welded Pipe — easier to produce due to low carbon content; stronger and more corrosion-resistant than standard welded pipe grades; produced to ASTM B673 / UNS N08904, size range 5mm–1219.2mm, thickness 0.5mm–20mm
- 904L Seamless Pipe — made from a single sheet of steel for higher strength, at a premium over welded pipe
- DIN 1.4539 Seamless Pipe — available OD 4mm–219mm, thickness 0.5mm–20mm, in single random, double random and cut lengths
- 904L SS ERW Pipe — tensile strength 490 MPa min, yield strength 220 MPa min, elongation up to 36%
- ASTM A312 TP904L Round Pipe — the most widely used form in this grade; strong, durable, low maintenance
- SA312 TP904L Square Pipe — preferred for structural support; can be cold-rolled for a smooth, corrosion-resistant finish
- AISI 904L Rectangular Pipe — interior-welded to shape, available with special outer diameters
- 904L 1.4539 Schedule 40 Pipe — for low and high-pressure applications, service up to 140°F
All forms can be manufactured, stocked and exported to custom shapes and sizes as per your requirement. Contact us for pricing on our Stainless Steel 904L Pipe/Tube range.
