Mild steel is carbon content less than 0.25% carbon steel, because of its low strength, low hardness and soft, so it is also called mild steel. It includes most ordinary carbon structural steel and a part of high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some of which are used for mechanical parts requiring wear resistance after carburizing and other heat treatment.
The annealed structure of low carbon steel is ferrite and a little pearlite, its strength and hardness are lower, plasticity and toughness are better. Therefore, its cold formability is good, can be used to roll, bending, stamping and other methods for cold forming. The steel also has good weldability. Low carbon steel generally refers to the carbon content of the steel between 0.10 and 0.25%. This kind of steel has low hardness, good plasticity, easy to use cold plastic deformation molding process, welding and cutting, often used in the manufacture of chains, rivets, bolts, shafts and so on.
The SPCC is also mild steel. SPCC is the brand of Japanese Steel (JIS series). Ordinary structural steel is mainly composed of three parts. The first part is the material, such as S (Steel) for steel, F (Ferrum) for iron; The second part represents different shapes, types and uses, such as P(Plate) for plate, T (Tube) for tube,K(Kogu) for tools; The third part represents the characteristic number, which is generally the minimum tensile strength. For example: SS400 -- the first S represents Steel, the second S represents "Structure", 400 is the lower limit tensile strength of 400MPa, the overall tensile strength of 400MPa ordinary structural steel.
SPCC- stands for common cold rolled carbon steel sheet and strip, whose chemical composition and mechanical properties are equivalent to the Chinese grade Q195 and Q215A. The third letter C is short for Cold. To ensure that the tensile test, add T at the end of the grade is SPCCT.
Electrophoretic paint film has the advantages of fullness, uniformity, flatness and smoothness of coating. The hardness, adhesion, corrosion resistance, impact performance and permeability of electrophoretic paint film are obviously better than those of other coating processes.
