301 Stainless Steel

The PSW Difference

301 Stainless Steel

Precision Steel Warehouse Type 301 is an Austenitic chrome-nickel stainless steel.

PSW stocks Type 301 stainless steel in the 1/4 hard, 1/2 hard, 3/4 hard, full hard, and extra hard tempers.

The chemistry of this alloy permits cold working to the ideal combination of mechanical properties desired for specific applications. To illustrate; in the Full Hard condition, it will maintain a minimum of 9% elongation in 2” as compared with Type 302 Full Hard at 2% approximately. This retained elongation on the part of Type 301 accounts for its great hardness, toughness and superior fatigue life in the finished part. In addition, it possesses a high strength-to-weight ratio. Type 301 work-hardens excessively - For this reason, its general demand is in the harder tempers to meet the specific mechanical properties required by our customers.


It is not heat-treatable for hardening purposes and is non-magnetic as annealed, but slightly magnetic following cold working. Type 301 possesses good heat and corrosion resistance and welds easily.


The mechanical and physical properties of type 301 stainless steel make it an ideal material for a multitude of applications both for industrial and consumer products. These including Springs, Gaskets, Shims, Fasteners, Tools, Blades, Automotive Parts, Aerospace Components, Kitchen Utensils, and Tableware, Electrical Components and many others.
