AISI 410 Stainless Steel Properties, SS410 Heat Treatment low alloy steel tubesheet designAISI 410 stainless steel is one of the most commonly used martensitic stainless steels. It contains about 12% Cr and therefore provides moderate corrosion resistance. Unlike austenite such as AISI 304 and AISI 316, martensite such as grade 410 is magnetic and can be hardened by heat treatment like carbon steel and low alloy steel .

Best practices for welding duplex stainless steels - Heat low alloy steel tubesheet design

Shielding gas plays an important role in welding of duplex stainless steels. Duplex is unique in that nitrogen plays a major role in both the formation of austenite as well as the pitting resistance of the weldment (as little as 0.05% in the lean duplexes and up to 0.40% in some of the super duplexes.). For maximum corrosion resistance, 2% low alloy steel tubesheet design Can a double tube sheet be used as a shell?Can a double tube sheet be used as a shell?In cases where it is critical to avoid fluid intermixing, a double tube sheet can be provided.
