Stainless Steel 317 Welded Pipes
Stainless Steel 317 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.
