Stainless Steel 317L Welded Pipe Manufacturer & Stockist in India
Chemical processing industries often require piping materials capable of withstanding aggressive acids and chloride-rich environments where conventional stainless steel grades may not provide sufficient corrosion resistance. Kamal Steels manufactures and stocks Stainless Steel 317 Welded Pipes engineered for such demanding applications. Manufactured in accordance with ASTM A312 and ASME SA312 standards using Stainless Steel 317 (UNS S31700 / WNR 1.4449), our welded pipes deliver exceptional resistance to pitting, crevice corrosion and chemical attack while maintaining excellent mechanical strength and fabrication characteristics.
The enhanced molybdenum content of Stainless Steel 317 provides superior corrosion resistance compared to conventional SS 316, making it particularly suitable for process industries handling aggressive chemicals and chloride-containing media. Our SS 317 Welded Pipes are widely used in chemical processing plants, fertilizer manufacturing, pulp & paper industries, petrochemical facilities, pharmaceutical production, marine engineering and process piping systems where long service life and reliable corrosion protection are essential.
Every Stainless Steel 317 Welded Pipe manufactured by Kamal Steels is produced using certified raw materials and undergoes comprehensive quality inspections to verify weld integrity, dimensional accuracy and material compliance. With extensive ready stock, project-specific manufacturing capabilities and prompt delivery, we supply dependable welded piping products that meet the performance requirements of industrial projects across India and international markets.
Thanks to their excellent corrosion resistance and low-carbon composition, Stainless Steel 317L Welded Pipes are widely used in industries where welded joints are exposed to aggressive chemicals, moisture, and elevated operating temperatures.

Frequently Asked Questions
Stainless Steel 317L Welded Pipe is a low-carbon austenitic stainless steel pipe with increased molybdenum content, offering superior resistance to pitting, crevice corrosion, and chemical attack. It is widely used in highly corrosive process environments.
The primary difference is the carbon content. SS 317L contains lower carbon than SS 317, reducing carbide precipitation during welding and providing better resistance to intergranular corrosion in welded applications.
Our Stainless Steel 317L Welded Pipes are manufactured in accordance with ASTM A312, ASME SA312, ASTM A358, ASTM A778, ASME B36.19M, and other applicable international standards.
We supply SS 317L Welded Pipes from 1/8" NB to 24" NB in various wall thicknesses, schedules, and custom lengths to meet different industrial requirements.
These pipes provide excellent corrosion resistance, outstanding weldability, improved resistance to chloride environments, high mechanical strength, long service life, and reliable performance in aggressive process conditions.
They are extensively used in chemical processing plants, petrochemical industries, marine applications, pharmaceutical manufacturing, pulp & paper mills, food processing, water treatment plants, and heat exchanger systems.
Every pipe undergoes Hydrostatic Testing, Positive Material Identification (PMI), Radiographic Testing, Flattening Test, Visual Inspection, Dimensional Inspection, and other quality checks before dispatch.
