Dear All,

Currently i have 2 questions, I would need your help in this.

1) I am currently wondering if there are any effects on the corrosion reading of a corrosion probe ER tubular for a Low temp Carbon steel probe & element replace with UNS K03005 and what are the impacts.

2) I have did some research on this UNS K03005 material and it calls out equivalent as ASTM 536 Gr B and some is ASTM 53 GR B, i am confuse of the 2 different standards that was called out.
