Carbon steel ball, also known as carbon steel ball, iron ball, iron ball, the main material is Q235, belongs to high quality low carbon steel, widely used in various industries. Carbon steel ball is divided into heat treatment and no heat treatment, that is, add fire and do not add fire, heat treatment of the surface hardness is high, that is, after carburizing treatment. Do not add heat treatment, hardness is not high, commonly known as iron ball, easy to weld, widely used for welding iron, hangers, crafts, and many other USES, the price is relatively cheap. Different hardness has different USES, only suitable is good.
Application: 1010/1015 carbon steel ball is a very common steel ball, has the characteristics of low price, high hardness, the use of a wide range of. Usually used for bicycles, bearings, pulleys, rails, crafts, shelves, universal ball, bags, hardware, but also can be used to grind other media.
Special: magnetic, metallographic structure for ferrite, often oily packaging, usually exposed to electroplating, galvanized, gold-plated, nickel plating, chrome plating, etc. Good wear resistance, hrc50-55.
Compared with bearing steel ball, wear resistance and hardness is not as good as the former (GCR15 steel ball hardness hrc60-66) : so the life of carbon steel ball is relatively short.
