Easy to form deep drawing stainless steel components
Deep Drawing Stainless Steel
Stainless steel is often deep drawn into difficult shapes and often without intermediate annealing. They are very easy to form, and the ductility of austenitic grades is much higher than that of carbon steel. Although ferritic steels have poor formability, they still have excellent ductility and can be easily deep drawn.
The benefits of stainless steel deep drawing
Compared with metal spinning and welding operations, the cycle time for each piece is shorter.
The integral part can be formed from a single piece of sheet or plate.
A fairly uniform material thickness can be achieved in the stainless steel shape.
Deep parts can be produced while avoiding welding.

Cost-saving techniques for stainless steel deep-drawn parts
During cold forming, stainless steel tends to undergo strain hardening, so minimal deformation is ideal.
The design should minimize the ratio of depth to diameter (or length and width) to avoid the need for a stress relief process.
Normally, before stress relief is needed, the limit is a 2-fold reduction; in 304 or 316, the ratio of depth to diameter does not exceed 1:1 in thicker materials.
Starting with approximately 14 gauge (0.074 inches / 1.75 mm) thick material, stretchability will decrease as the metal thickness decreases.
