Material Metallurgy & Chemical Resistance
Selecting the right stainless steel alloy ensures lasting, dependable corrosion resistance across demanding industrial pipelines:
| Material Grade | Key Characteristics | Recommended Industrial Use |
|---|---|---|
| SS 304 / 304L | Classic 18/8 austenitic stainless steel with excellent formability and general corrosion resistance. | Food processing, sanitary water piping, and general industrial lines. |
| SS 316 / 316L | Formulated with 2-3% Molybdenum for superior resistance against chlorides and pitting. | Marine environments, chemical reactors, and offshore process piping. |
| SS 321 / 321H | Titanium-stabilized alloy preventing chromium carbide precipitation during welding up to 870°C. | High-temperature exhaust manifolds, boilers, and petrochemical lines. |
| SS 904L & Duplex | High-performance alloys with extreme resistance to sulfuric acids and stress corrosion. | Phosphoric acid plants, desalination units, and severe chemical scrubbers. |
