Black Q235 Low Carbon Steel Coil Hot Rolled 0.17mm-3.5mm Wall
Thickness
Mild steel (Low carbon steel) is a carbon steel with carbon content
less than 0.25%. It is also called mild steel because of its low
strength, low hardness and softness. It includes most of the
ordinary carbon structural steel and part of the high quality
carbon structural steel, most of the engineering structural parts
without heat treatment, and some of the carburizing and other heat
treatment for wear-resistant mechanical parts.
The annealed structure of low carbon steel is ferrite and a little
pearlite, with low strength and hardness, good plasticity and
toughness. Therefore, its cold formability is good, can be used to
roll, bending, stamping and other methods for cold forming. This
steel also has good weldability. Low carbon steel with carbon
content from 0.10% to 0.30% is easy to accept all kinds of
machining such as forging, welding and cutting, and is often used
in the manufacture of chains, rivets, bolts, shafts, etc.
