Welders and piping experts prefer low carbon steel for things like
boiler plates, wire products and seamless tubing and piping uses.

Low Carbon Steel Contents and Use
Low carbon steel is composed of 0.04 – 0.30 percent carbon. Welders
and piping experts prefer low carbon steel for things like boiler
plates, wire products and seamless tubing and piping uses. Auto
manufacturers typically prefer low carbon steel for vehicle body
panels. If the low temperature carbon steel piping is seamless, it
can be installed when processing or manufacture piping requires low
temperatures to avoid negative impact on this type of piping. One
example of use of low temperature carbon steel pipe would be in
processes where refrigerants are required to be 50° F. If this is
the case, choose ASTM A333 Grade 6 Low Temp Seamless Carbon Steel
for pipes transporting refrigerated process materials through a
system. This is a simple guide to new installations of low carbon
steel pipes with chemical components that include:
. Carbon (max) 0.30
. Manganese at 0.29-1.06
. Phosphorus (max) 0.025
. Sulfur (max) 0.025
