Sixfold Tubos offers
a wide-range of carbon steel pipe products. The term carbon steel pipe
can be used to describe a wide range of metal tubular goods whose main
alloying element is carbon in a range of 0.12%-2%. Apart from carbon
elements like chromium, cobalt, molybdenum, nickel, niobium, titanium,
tungsten, vanadium & zirconium can be added to attain respective
alloying effect.
For an example A333 grade 6 pipe
has high tensile strength and impact properties used at low temperatures
application as compared to A106 Grade B pipe with low tensile strength
and used at room temperatures or higher temperatures. This is achieved
by addition of manganese above the 0.9%, which is limited to 0.65% in
A106 pipe.
In general, a pipe is referred as a
carbon steel pipe when the maximum specified content of Manganese –
1.65%, Silicon – 0.6% & copper 0.6 % does not exceed the limit
prescribed.
ASTM & EQUIVALENT STANDARDS OF CARBON STEEL & ALLOY STEEL PIPES
ASTM A53 Grade A Specification
ASTM
A53 Grade A Carbon Steel Seamless Pipes are Low Carbon Steel Pipes with
0.25 % carbon content with combination of 0.95 % manganese. These Pipes
are also known as mild steel pipes and tubes. ASTM A53 Grade A Pipes
are low-cost Pipes easy to form and shape. These pipes are manufactured
as per ASTM Specification and commercially referred as cs pipes or ms
pipes. Low Carbon Steel Pipes are not as hard as hig carbon steel
pipes,Though carburizing can increase its surface hardness.
