DIN 1.4404 / UNS S31603 stainless steel tube fittings
Our stianless steel pipe fittings have excellent strength, hardness, mechnical properties, corrosion resistance ability, good formability, and less distortion. These characteristics make us to be best pipe fitting manufacturer and exporter in the oil and gas pipeline industries.
Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. They are widely used in various industries including petrochemical, oil and gas, power generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing, textiles and others.
