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.
