Killed Carbon Steel is a process of deoxidation that is performed during the steel making process.Normally, ASME B&PV Code requires steels that have 0.24% or greater carbon contents to be killed (fully de-oxidized) using either Al or Si additions, and especially those steels that fall under a forging grade.

LaoYes, there is a difference between regular carbon steel and killed carbon steel. Killed carbon steel is a process of deoxidation. To make killed carbon steel Silicon or Aluminum is added to the melt. This removes oxygen generated during steel making in the furnace and makes the steel cleaner, without voids and refines the microstructure (fine grain) and thus improves the properties of the steel. In practice, when a carbon steel contains a residual content of 0.10 Silicon in the chemical composition, it is considered as a Killed carbon steel.Examples are ASTM specifications A 516 Gr. 60, 70 (Plates),; A 106 Gr. B, A 333 Gr. 6 (Pipe); A 105, A 350 Gr. LF2 (forgings) etc.
CARBON STEEL-Steel is classified as carbon steel when no
minimum content is specified or required for aluminum, boron,
chromium, cobalt, columbium, molybdenum, nickel, titanium,
tungsten, vanadium, or zirconium, or any other element added
to obtain a desired alloy effect; when the specified minimum
for copper does not exceed 0.4% or when the maximum content
specified for manganese does not exceed 1.65%; silicon
0.6%; copper 0.6%.
KILLED STEEL-Steel deoxidized with a strong deoxidizing agent
such as silicon or aluminum in order to reduce the oxygen
content to such a level that no reaction occurs between carbon
and oxygen during solidification of the molten steel in the
ingot. Killed steel products will produce a more chemically
uniform analysis from the bottom to the top of the ingot.
Killed steel is considered having less chemical segregation
than semi-killed or rimmed steel.

What is the difference between ms and cs steel?
MS stands for mild steel. This is steel than only has a small about of carbon. It's strong, but not easily tempered. CS stands for carbon steel. In carbon steel, the main alloying element is carbon.
What is the difference between en8 and en24?
En8 is low carbon steel and it can be toughned. En24 is medium carbon steel and it is generally called forged steel.
What is the difference between high carbon steel and low carbon steel I know one has more carbon than the other?
Low carbon steel, is very soft, and can be easily shaped, but high carbon steel is extreamly stong and is used for springs or high strenght wire
Are there killed carbon steel pipe-fittings?
Yes. Argon gas welding is often used for killed steel welding to inhibit the oxidation of the steel.
What is the difference between mild iron and mild steel?
Iron is the pure element, mild steel, or any steel is iron with a little bit of carbon added. The iron becomes mild steel, steel or any other type of steel depending on how much carbon is added to the iron.
