NACE MR-0103 -2012 Interpretation of PWHT for 410SS
NACE MR-0103 -2012 Interpretation of PWHT for 410SS
(OP)
Please help me understand this section clearly :
Under section 2.4.1 for manufacturing 410SS or CA15, the heat treatment called out is a double temper after austenitizing. However for the same alloy after welding under section 2.4.3 the standard indicates a single temper only.
ALso, the filler metal manufacturers recommend a double temper in order to meet the NACE hardness
What is the correct interpretation?
Greatly appreciate your insight.
