Steady-state heat transfer does not change with time - because - that is the definition of steady-state, i.e. "steady-state" means "does not change with time".
As for why heat transfer might be steady state - that would be a consequence of the driving forces and physical conditions remaining constant with time. For example:
Heat source remains the same temperature
Heat sink remains the same temperature
Heat source remain in the same position relative to each other, both in terms of distance and orientation.
Surface areas of heat source and heat sink remain the same.
Any intervening medium remains the same composition, temperature, density, and pressure.
If convection is occurring, flow rates remain constant.
If radiative heat transfer is occurring, any intervening medium has constant transmissivity, reflectivity, and absorbtion.
If radiative heat transfer is occurring, radiating and absorbing surfaces maintain constant radiative and absorbing properties.
There are a few other factors that can influence steady-state heat transfer, but these are a good description of the most important ones.
Steady state conditions are met when the ignition process has been shut off and furnace has been running for about one minute. When the steady state current is found set the anticipator to that current.
In steady state condition of heat transfer there is no temperature variation with time.
The abstract noun form of the adjective 'steady' is steadiness as a word for the state of continuing without change; a word for a concept.
Steady state of concentration of ozone means no change in its concentration. It maintains the level to be accurate.
The correponding noun to the adjective steady is steadiness.
a steady drop in temperature is called a gradual front
All battery is DC battery. DC is meaning Direct Current. Battery voltage is steady, not change, except reduce when battery go flat.
In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.
it is the response of a system with respect to the input as a function of time
AC rises with respect to time but DC is steady.
the term steady implies no change at a point in time, however particle speed can change from point to point. ie, water novel, steady flow with increase in velocity

No. Steady is an adjective. The adverb form would be steadily.
steady: A steady flow is one in which the conditions (velocity, pressure and cross-section) may differ from point to point but DO NOT change with time. unsteady: If at any point in the fluid, the conditions change with time, the flow is described as unsteady.
The abstract noun form of the adjective 'steady' is steadiness as a word for the state of continuing without change; a word for a concept.
If velocity is steady and doesn't change, then there is 0 acceleration.
Steady state of concentration of ozone means no change in its concentration. It maintains the level to be accurate.
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
