Somebody could suggest me wich standard I have to specify for filter internals in 2205 duplex material. I see the grade S32205 for ASTM A 240/ASTM A 276/ASTM A 479. Which is the difference beetween these three standard mentioned, apparently seems to be very similar. Thank you in advance for your help
