Steel Pipes by Material » Mild Steel Pipes & Tubes

Mild steel contains carbon alloy of 0.16 to 0.29% and is therefore not ductile. The mild steel pipes are coated with copper and thus resist corrosion however, extra care has to be taken to keep away from rusting. The 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 most frequently used mild steel are - A-106 & A-S3. A-106 comes under both A & B grade and is used for cold or close coiling.

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, readily available, and relatively cheaper than other metals. The life expectancy of such steel could go up to 100 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.
