S195T
EN 10219 S195T Carbon steel tubes are also called mild steel tubes. These pipes are manufactured to EN specifications and are commercially known as CS or MS pipes. The hardness of low carbon steel tubes is not as good as that of high carbon steel tubes, but carburizing can increase its surface hardness.
This document describes the criteria for circular non-alloy steel tubes suitable for welding and threading, as well as a variety of alternatives for tube end and coating finishes. This document applies to tubes with specified outside diameters ranging from 10.2 mm to 165.1 mm (thread sizes 1/8 to 6) in two series, medium and heavy, and three types of designated thicknesses.

EN 10255 Grade S195T Properties
The chemical composition of EN 10219 S195T has a considerable impact on its mechanical properties. Among all the elements of EN 10255 S195T. Carbon is a toughening element. Silicon contributes to strength. Manganese is essential austenite stabilizing element that contributes to texture structure creation and increases firmness, strength, and wear resistance. Phosphorus reduces plasticity and toughness, as well as the appearance of cold brittleness. Meanwhile, it may considerably raise the strength of steel and improve the stability of atmospheric corrosion. Sulfur increases the hot brittleness of steel.

NOTE The steel specified in this document is weldable, however, when subsequently welding tubes produced according to this documented account should be taken of the fact that the behavior of the steel during and after welding is dependent not only on the steel but also on the conditions of preparing for and carrying out the welding.
