The most frequently used mild steel are ASTM A-106 & A-S3. A-106 comes under both A & B grade and is used for cold or close coiling.

Mild steel contains carbon alloy of 0.16 to 0.29% and is therefore not ductile. The mild steel pipes hardness of the mild steel could be increased through carburizing in which the steel is heated below melting point in presence of another material and again by quenching, the outer surface of the carbon becomes harder maintaining a soft core.


The different variations of carbon steel pipe fittings and pipes are measured by their percentage of carbon content that has been mixed with iron. Here is a quick list of the categories:

Mild carbon steel: 0.05-0.15
Low carbon steel: 0.16-0.29
Medium carbon steel: 0.30-0.59
High carbon steel: 0.60-0.99
Ultra-high carbon steel: 1.00-2.00

Mild steel pipe Availability and usages:
Mild steel is available in a variety of structural shapes that are easily welded into pipe, tube, tubing etc. Mild steel pipes and tubing are easy to fabricate. The life expectancy of such steel could go up to 150 years if it is well protected. Mild Steel pipes and tubing are used for structural purpose and mechanical & general engineering purpose. It is also used for drinking water supply and the use of chlorination and sodium silicate inhibit corrosion in mild steel pipes.
