Neeka Tubes offer the most high-quality supply of SS 316 Pipe Fittings.These SS 316 Pipe Fittings also offer higher creep, stress-to-rupture, and tensile strength at elevated temperatures. These Stainless Steel 316 Butt Weld Fittings are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels.

While similar to Type 316, these 316 Stainless Steel Pipe Fittings exhibit better corrosion resistance and are stronger at elevated temperatures. The higher nickel and molybdenum content in 316 Stainless Steel Butt Weld Fittings allows it to demonstrate better overall corrosion resistant properties than 316, especially with regard to pitting and crevice corrosion in chloride environment.

SS 316 / 316L Pipe Fittings, which is often utilised in process streams containing chlorides or halides. The austenitic structure of Stainless Steel 316 Pipe Fittings also gives these grades excellent toughness, even down to cryogenic temperatures.

Neeka Steel is trust to be most Excellent  SS 316 Pipe Fittings Suppliers INDIA.
