Austenitic Stainless Steel

Austenitic Stainless Steel
Sheets • Coils • Plates • Pipes • Rods

Austenitic stainless steels are the most widely used stainless steel family, known for their excellent corrosion resistance, high ductility, good weldability, and superior formability. They contain high levels of chromium and nickel, with low carbon content, and are non-magnetic in the annealed condition.

Key Features

Excellent corrosion and oxidation resistance
High ductility and formability suitable for deep drawing
Non-magnetic in annealed condition
Good weldability without post-weld heat treatment
High toughness even at cryogenic temperatures
Resistant to acids, alkalis, and chloride environments (grade dependent)

Available Product Forms

Sheets
Coils
Plates
Pipes (Welded & Seamless)
Rods / Bars

Applications

Chemical processing equipment
Food and beverage processing
Pharmaceutical equipment
Oil & gas industry components
Heat exchangers and boilers
Architectural structures and cladding
Automotive and aerospace components
Kitchenware, utensils, appliances
