Stainless Steel, 304L
This grade is a Cr-Ni Austenitic Steel, which is the most versatile and most widely used Stainless. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts. This grade has many applications such as Nuclear, Food processing equipment, Heat Exchangers, Springs and Threaded Fasteners.
