Introduction
Stainless steel 310L nitric acid grade (NAG) is designed to be used in nitric acid applications. The carbon and silicon contents are well controlled in this steel to produce a more stable austenite microstructure that is free of intermetallic or carbide precipitations.
Stainless steel 310L NAG is however not recommended for highly oxidizing nitric acid solutions or concentrated nitric acid purposes.
The following datasheet provides an overview of stainless steel grade 310L NAG.
