class Stainless_Steel_304(Solid):
"""
A class representing stainless steel 304 material properties for aerospace
and cryogenic applications.
Attributes
----------
density : float
Material density in kg/m³ (8000).
thermal_conductivity : float
Heat conduction coefficient in W/(m·K) (≈1 at cryogenic temperatures).
yield_tensile_strength : float
Stress at which material begins to deform plastically in Pa (548e6).
Notes
-----
Stainless steel 304 is an austenitic chromium-nickel alloy commonly used in
cryogenic storage tanks, aerospace structures, and thermal systems. It offers
excellent corrosion resistance and strength retention at low temperatures,
but has lower thermal conductivity compared to aluminum alloys.
**Definitions**
'Yield Strength'
The stress at which a material begins to plastically deform.
'Ultimate Strength'
The maximum stress that a material can withstand before fracture.
'Thermal Conductivity'
The property of a material to conduct heat, measured in watts per
meter-kelvin.
"""
def __defaults__(self):
"""
Sets material properties at instantiation.
Parameters
----------
None
Returns
-------
None
Notes
-----
Uses representative values for stainless steel 304 at cryogenic temperatures.
