304/304L Deep Draw Quality Stainless Steel

Type 304 deep draw quality (304 DDQ) stainless steel is an austenitic chromium-nickel stainless steel that is used in special applications that require deep drawing and excellent formability. 304 DDQ also has an elevated nickel content that provides higher corrosion resistance.

304 DDQ Stainless Steel Applications:

Automotive

  • Fuel tanks

Kitchenware

  • Sinks and other domestic appliances

Magnetic Properties:

304 flat rolled stainless steel is generally non-magnetic and becomes slightly magnetic only when cold-worked.

Forming:

304 deep draw quality stainless steel has great forming capabilities that allow for severe drawing applications.
