301 Full Hard Tempered Stainless Steel Sheet & Coil - AMS 5519

301 Full Hard is an austenitic stainless steel which differs from other forms of 301 offered by United Performance Metals in that it has been cold rolled to its full hard condition. This increases the metal's attractiveness for forming and increases its fatigue life. In its full hard condition, type 301 has a tensile strength of 185,000 PSI minimum, and a minimum yield strength of 140,000 PSI. The combination of hardness and toughness make it ideal for springs.
