Series 300 Stainless Steel Sheets
Austenitic and Heat-Resistant Grades
Series 300 includes a wide range of austenitic stainless steel grades. Depending on their chemical composition, mechanical properties, corrosion resistance and operating conditions, these grades are used across various industries.

Values marked with ≤ indicate maximum permitted limits. Values shown as ranges indicate the minimum and maximum permitted content of each element.
A dash indicates that no specific limit is listed for that element in this table. It does not mean that the element is absent.
For stabilized grades 321 and 316Ti, the titanium content must comply with the specified ratio and limit shown in the Other Elements column.
The actual chemical composition of each shipment must be verified against the manufacturer's Mill Test Certificate (MTC) and the edition of the standard agreed upon in the purchase order.
