igh quality carbon structural steel: used for mechanical parts with high requirements.Common brands include steel 10, 70 and 15.The brand number is means "carbon content".For example,the average carbon content of No.15 steel is 0.15%,while that of Steel No.40 is 0.40%.The higher the carbon content,the stronger and harder it will be higher,but it will be more brittle.
Structural alloy steel:widely used in all kinds of important machinery important parts.The commonly used types are 20Cr, 40Cr (gear, shaft, rod), 18CrMnTi, 38CrMoAlA (important gear, nitriding parts) and 65Mn (spring steel).The commonly used types are 20Cr, 40Cr (gear, shaft, rod), 18CrMnTi, 38CrMoAlA (important gear, nitriding parts) and 65Mn (spring steel),the A at the end represents shows high quality steel.The chemical symbols of the alloy elements in the middle mean Mn manganese, Si silicon,Cr chromium,W tungsten,Mo molybdenum,Ti titanium,AL aluminum,Co cobalt,Ni Ni,Nb niobium,B boron,V vanadium.
