*** Theoretical burst and working pressure in psi to 100 degrees F
Pressure Formula: Internal Burst = 2 St/D Where P = Internal pressure psi
S = Tensile stress psi
t = Minimum wall thickness in inches
D = Nominal outside diameter in inches
Working pressure = 1/4 internal burst pressure
Tensile Requirements (304, 304L, 316, 316L):
A minimum of (2) tests per work order / heat number
Minimum yield strength = 30,000 psi
Minimum ultimate strength = 75,000 psi
Minimum elongation = 35%
Hardness Requirements (304, 304L, 316, 316L):
A minimum of (2) tests per work order / heat number
Maximum hardness* = 74 30T or 90 RB
* Not applicable to sizes < 0.250 I.D. unless specified
