Q235 Micro Metal Beads Small Carbon Steel Ball Magnetic Steel Balls 0.3mm 0.5mm 0.6mm



Using our standard heat treating procedure, this material will harden to a minimum of 60 on the Rockwell "C" scale (60 HRC). The hardness may be measured between parallel ground flats.


If the reading is taken on a spherical surface, it is corrected for the curve. The HRC scale uses 150 Kilogram Load ( approximately 330 lb. ) applied to a conical diamond brale indenter.


This material is commonly used for gauge ( gage ) balls. This material is considered a Ferrous Metal.



Carbon steel balls have excellent surface quality ,high hardness and high load bearing capacity as a result of through hardening.


According to the different materials can be divided into Low carbon steel ball Medium carbon steel ball and High carbon steel ball,


The main material is 1010-1015,1045,1085


According to the hardness can be divided into Soft ball(HRC28) and hard ball (HRC55-60 after heat treatment).
