Explaining The Differences Between Stainless Steel 304 and 316

301-1/4 Hard is an austenitic stainless steel that has been cold rolled to its 1/4 hard condition. This increases the metal's attractiveness for mild drawing, stretching and forming operations. At 1/4 Hard, Type 301 has a tensile strength of 125,000 PSI minimum, and a minimum yield strength of 75,000 PSI.

We supply 301-1/4 Hard stainless steel sheet in a variety of lengths and widths and can custom cut to your exact specifications.  Our 301-1/4 Hard coil can can also be slit to your desired width.
