Materials
I usually deal with steel and I have general understanding of NACE requirements for carbon and stainless steels. I have a requirement for ductile iron and I am a little unsure.
NACE states that ASTM A395 ferritic ductile iron is acceptable. However there are multiple grades under A395 (65-45-12 / 60-40-18 etc). Does anyone know if all grades are acceptable for valves/pumps or if any are excluded for sour service?
Thanks in advance
