301-1/2 Hard Stainless Steel Sheet & Coil

Properties

Stainless Steel

Type 301 (UNS Designation S30100)

Physical Properties

Melting Range: 2250-2950°F (1399-1421°C)
Density: 0.2850 lb/in³ (7.88 g/cm³)
Specific Gravity: 8.03
Modulus of Elasticity in Tension: 28 x 10⁶ psi (193 GPa)^*

^* In the cold worked condition, the modulus is lowered.

Linear Coefficient of Thermal Expansion
Temperature Range		Coefficients
°C	°F	cm/cm°C	in/in/°F
20-100	68-212	16.6 x 10^-6	9.2 x 10^-6
20-300	68-572	17.6 x 10^-6	9.8 x 10^-6
20-500	68-932	18.6 x 10^-6	10.3 x 10^-6
20-700	68-1292	19.5 x 10^-6	10.8 x 10^-6
20-871	68-1600	19.8 x 10^-6	11.0 x 10^-6

Since the expansion coefficient is higher than that of many other metals and alloys, this characteristic should be considered in the design of equipment involving Type 301 and other materials of construction.
