S32202 Pipes & Tubes are stainless steel pipes & tubes with strength, excellent corrosion resistance and chloride stress corrosion cracking resistant properties. Also known as UNS S32202, lean duplex 2202 and EN 1.4062, S32202 Pipes & Tubes are made of approximately 22% chromium, 2% nickel, and 0.2% nitrogen. Its minimal yield is 450MPa more than 304L, so under the equal pressure it can reduce the thickness of walls, which can reduce weight and cost. The pipes are produced to ASTM A790 standards, and tubing according to ASTM A789 standards. S32202 Pipes & Tubes used in Chemical Processing, Water Systems, Storage Tanks and Industrial piping. Amardeep Steel is a most trusted supplier of S32202 Pipes & Tubes in India.
