High-quality Carbon Steel Wire and its Main Chemical Components
Carbon steel wire is a type of steel wire with high carbon content, which can be divided into three categories: low carbon steel wire, medium carbon steel wire and high carbon steel wire. Commonly used steel grades for carbon steel wires include Q195, Q215, Q235, 45#, 50#, 65# and 70#.
Low carbon steel wire (carbon content of 0.12%-0.29%) belongs to low-carbon steel, usually manufactured with annealed or soft state, generally used for cold heading, weaving, welding, etc. The main chemical components of low carbon steel wire are 1008, C10, C15, C15M, C20, C25, etc. The chemical components are C: 0.06%-0.15%, Si: 0.17%-0.37%, Mn: 0.25%-0.60%, P: 0.14% Max., S: 0.26% Max.
Medium carbon steel wire (carbon content of 0.3%-0.6%) belongs to medium-carbon steel, which is also known as medium-carbon high-speed steel. It is a high-speed steel used for cutting tools and is commonly used to make springs, axle shafts and bearing components. Its main chemical components are 45#, 55# and 60# steel, commonly known as spring steel. Its chemical components are C: 0.37%-0.44%, Si: 0.17%-0.37%, Mn: 0.50%-0.80%, P: 0.14% Max., S: 0.26% Max.
High carbon steel wire (carbon content of 0.6%-0.95%) It is a kind of high-carbon steel. It has good abrasion resistance, tensile strength and good fatigue strength. It is mainly used to make flat springs and shaped cross sections. Its main chemical components are 65# and 70# steel, commonly known as high-carbon steel wires. Its chemical components are C: 0.40%-0.90%, Si: 0.17%-0.37%, Mn: 0.50%-0.80%, P: 0.14% Max., S: 0.26% Max.
In summary, low carbon steel wire belongs to low-carbon steel, and its main components are 1008, C10, C15, C15M, C20, C25, etc. Medium carbon steel wire belongs to medium carbon steel, and its main components are 45#, 55# and 60#. High carbon steel wire belongs to high-carbon steel, and its main components are 65# and 70# steel. They differ mainly in their carbon content and can be used for different purposes according to the different needs of customers.
