ASTM A790 UNS S82121 Stainless Steel Tube For General Corrosive Service with High Strength Requirements
ASTM A790 UNS S82121 Stainless Steel Tube For General Corrosive Service with High Strength Requirements
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 UNS S82121 is its excellent combination of high mechanical strength (approximately double the yield strength of 304/316 austenitic) and good resistance to stress corrosion cracking (SCC).
