Frequently Asked Questions
What is ASTM A240 Grade 321 Plate?
ASTM A240 Grade 321 Plate is a titanium-stabilized austenitic stainless steel plate designed to resist intergranular corrosion after exposure to elevated temperatures. It is commonly used in heat-resistant and welded components.
What is the difference between SS 321 and SS 304 plates?
SS 321 contains titanium, which provides better resistance to carbide precipitation during welding and high-temperature service. SS 304 does not have this titanium stabilization and is generally preferred for less demanding temperature conditions.
Where are Stainless Steel 321 Plates commonly used?
Stainless Steel 321 Plates are commonly used in aerospace components, heat exchangers, chemical processing equipment, furnace parts, exhaust systems and other applications requiring good corrosion resistance at elevated temperatures.
