Austenitic Stainless Steels

Austenitic stainless steels are the most widely used grades, known for their excellent corrosion resistance, formability, and weldability. These grades contain high levels of chromium and nickel, making them ideal for diverse industrial applications.

304/304L Steel

304 / 304L

Most common austenitic grade with 18% chromium and 8% nickel. Excellent corrosion resistance and formability.

Chromium: 18-20%
Nickel: 8-10.5%
Carbon: 0.08% max, 304L

Applications:

Food processing, kitchen equipment, chemical containers, architectural applications

316/316L Steel

316 / 316L

Enhanced corrosion resistance with molybdenum addition. Ideal for marine and chemical environments.

Chromium: 16-18%
Nickel: 10-14%
Molybdenum: 2-3%

Applications:

Marine equipment, pharmaceutical industries, chemical processing, surgical instruments

321/321H Steel

321 / 321H

Titanium stabilized grade for high temperature applications. Excellent resistance to intergranular corrosion.

Chromium: 17-19%
Nickel: 9-12%
Titanium: 5xC min

Applications:

Aircraft exhaust systems, expansion joints, boiler tubes, heat exchangers
