Mild carbon steel Pipe
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
In Form :
Round, Square, Hydraulic Tube & Horn Tube.
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.
