Q235 Mild Carbon Steel Plates

What Is Mild Steel Plate? Steel is mostly composed of iron. Depending on different amounts of carbon content, there are low-carbon steel (also called mild steel sheet metal  or plain carbon steel), medium-carbon steel, and higher carbon steel. The following chart shows the differences and characteristics of the three steel types:   Carbon content (wt. %) Microstructure Characteristics Examples Low-carbon steel (Mild steel) Less than 0.25 Pearlite, ferrite Soft, cheap, very ductile, easy to machine and weld AISI105, AISI 316L, Q195, Q215, Q235, 08F, 15Mn, 20Mn Medium-carbon steel 0.25 to 0.60 Martensite Reasonab…
