Marine engineering

ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing,either hot-finished or cold-finished.

S32750, a duplex stainless steel variety, is used in heat exchangers and cold showers and devices that are resistant to seawater, high temperature and concentrated nitric acid in oil refining, fertilizer, papermaking, petroleum, chemical and other industries.

Stainless Steel 310H (UNS S31009) is a higher carbon version of 310 Stainless Steel which has a higher carbon content than 310 and is typically used in environments where thermal cycling and resistance to high temperature corrosive conditions is critical.
