Applications Springs, Fasteners, Utensils, Food Service, Appliances, Automotive Trim, Clamps Description Type 201 stainless steel is an austenitic chromium-nickel-manganese stainless alloy. It was developed mid century to conserve nickel and it is used as an alternative to type 301 in some tempered applications. Because of 201’s relatively high yield strength in the annealed condition, use of 201 is limited. Type 201 is generally used in the tempered condition particularly for springs and fasteners. 201 Stainless will retain a comparable ductility to 301 even with the higher yield strength. Chemistry Typical Carbon: 0.15 max Manganese: 5.50- 7.50 max Phosphorus: 0.060 max Sulfur: 0.030 max Silicon: 0.75 max Chromium: 18.00- 20.00 max Nickel: 3.50- 5.50 Nitrogen: 0.25 max Iron: Balance Physical Properties Density: 0.283 lbs/in3 7.81 g/cm3 Electrical Resistivity: microhm-in, (microhm-cm): 27.0 (68.5) Specific Heat: BTU/lbs./°F (kJ/kg/K): 32-212 °F (0-100 °C): 0.12 (0.50) Thermal Conductivity, BTU/hr/ft/ft2/°F (W/m/K): At 212 °F (100 °C): 9.4(16.2) At 932 °F (500 °C): 12.4 (21.4) Limitation of Liability and Disclaimer of Warranty: In no event will Ulbrich Stainless Steels & Special Metals, Inc., be liable for any damages arising from the use of the Information Included In this document or that It Is suitable for the 'applications' noted.
