What is the ASTM equivalent of en 10222-5?
The primary ASTM equivalent to the EN 10222-5 standard for stainless steel forgings (pressure purposes) is ASTM A182/A182M (Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service). Specific grades under EN 10222-5 match to specific ASTM A182 grades:
EN 1.4462 (X2CrNiMoN22-5-3) / Duplex 2205: Matches ASTM A182 F51 (UNS S31803) or F60 (UNS S32205).
EN 1.4410 (X2CrNiMoN25-7-4) / Super Duplex 2507: Matches ASTM A182 F53 (UNS S32750).
EN 1.4501 (X2CrNiMoCuWN25-7-4): Matches ASTM A182 F55 (UNS S32760).
EN 1.4571 (316Ti): Matches ASTM A182 F316Ti.
These standards are often used interchangeably for forged pressure components like flanges and valve parts.
EN 10222-5 1.4571 flanges typically refer to EN 1092-1 flanges made from 316Ti stainless steel forgings, where 316Ti is a stabilized version of the austenitic stainless steel 316. This steel grade corresponds to the steel designation X6CrNiMoTi17-12-2, equivalent to ASTM A182 F316Ti.
Various methods have been employed to minimize or prevent sensitization in 316 stainless steel. If the sensitization is sufficiently mild, solution annealing is the only method to repair sensitized stainless steel. The addition of titanium in 316Ti type (1.4571) stainless steel keeps chromium in solid solution even after prolonged exposure to the sensitization temperature range. In short, titanium stabilizes the stainless steel and prevents sensitization. 1.4571 (316Ti type) flanges, both in the as-manufactured and sensitized states, should meet the intergranular corrosion test requirements specified in EN ISO 3651-2.
