I would like to utilize 4130 HR and HT plate as a pressure containing component per API 16A (requires pv-grade), but unfortunately, "4130 plate" appears to be only as a structural grade (ASTM A829) available.
My quastioins are:
1) Is there a "4130 plate" available in PV grade?
2) If not, can it be qualified for this purpose, or do I have to use an ASTM Pressure Vessel plate grade? (The required material properties could be easily satisfied by the 4130 structural grade plate.)
3) Which other readily available plate-material could be utilized?
Required proerties are:
Sy,min = 75ksi,
Min. Elong. = 18%,
Red in Area = 35%,
HRC,max =23
NACE-conform
Thanks
