Semi-Killed Carbon Steel is Partially deoxidized and some free Oxygen is still left in the steel. Properties of semi-killed steel in between fully killed and rimmed steel. Steel produced without deoxidization is known as rimmed steel. Which is brittle and has poor elongation. Only fully killed steel is used in process piping.

Killed Steel as Piping Material » The Piping Engineering World

Killed Steel is a Deoxidized steel that has all of the oxygen removed from the melt during the steel making process. Liquid steels contain dissolved oxygen after their conversion from molten iron, but the solubility of oxygen in steel decreases with cooling. As steel cools, excess oxygen can cause blowholes or precipitate FeO.

Sep 27, 2006 · The SA-266 Grades 1-4 are killed steels because of the required silicon additions as alloying elements per ASME SA 266 Table 1. 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.

I am reviewing an MTR for carbon steel pipe. Our Design calls for Grade 290 steel as per CSA 245.1. In the MTR, the material is certified to three different specs: ASTM53/API5L/CSA 245.1, all for the correct grade. Both API5L and CSA 245.1 require that the steel be semi or full killed while ASTM53 has no mention of it. Our design requirement is that the steel shall be fully killed. As for the deoxidizing …
