Yes, there is a difference between "killed" and "fully killed" steel. "Killed steel" refers to steel that has been treated to remove dissolved gases, typically by adding a deoxidizing agent, which improves its mechanical properties and reduces the likelihood of defects. "Fully killed steel" indicates a more complete deoxidation process, resulting in a more uniform composition and enhanced performance characteristics. The distinction can be important in applications requiring high strength and reliability.

In short Killed or fully killed steel (steels are also produced as semi killed steel) normally uses Si & Al for completely stopping (killing) the reaction between carbon and oxygen in molten steel. 1. Addition of small amount of Al helps in refining the grain size which in turn increases toughness of steel, an important requirement for steel against low temperature brittleness. 2. Killed steel is also comparatively cleaner (freedom from inclusions, stringers, etc) and therefore have better properties.
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.

what is the difference between product analysis and heat analysis
Not much, avaliability is the same also. Our default has changed to killed carbon steel.

Killed steel is a type of steel that has been treated with deoxidizers, such as aluminum or silicon, to remove oxygen and prevent the formation of gas bubbles during solidification. This results in a more uniform and high-quality material. Rimmed steel, on the other hand, is produced without such deoxidizers, allowing some gas to remain, which creates a rim of purer steel around a more impure core. Consequently, killed steel generally has better mechanical properties and is used for more demanding applications compared to rimmed steel.
