Profile
GCr15 steel has a small alloy content and good performance. Chromium (CR) has a tendency to increase hardness, toughness and wear resistance of steel. Chrome steel is a chrome Alloy carbon steel, not a chrome plated steel.
Although these chromium steel balls have good rust resistance, but it is recommended to use a dry cloth to wipe clean after use and apply a layer of oil, so that they have better rust resistance, to extend their service life.
High Quality Graded Hardened Chrome Steel Ball bearings made from Chromium GCr15 steel. Hardened to 60-67 Rockwell Scale equivalent to 700-900 HV (Vickers Scale) and are hardened all the way through the ball. These are the same hardened steel balls used to manufacture bearing assemblies and have a high duty and life cycle.
The high-carbon chromium bearing steel is a high-carbon alloy steel with 1.30~1.65% chromium. It is characterized by a more uniform and stable structure after heat treatment, high hardness, high uniformity, good wear resistance, high contact fatigue strength, and good dimensional stability and corrosion resistance after annealing, its cutting performance is good and the price is relatively cheap. This steel can meet bearing requirements under normal working conditions.
In addition, the company has advanced production equipment and complete testing instruments, including low-speed cold headers, high-speed cold headers, ball flashing machine, ball crushers, grinding machine and heat treatment devices, and through rockwell instruments, electronic compression testing machine, optical microscope, metallographic microscope, appearance profiler meter, laser surface roughmeter, automatic appearance detector and steel ball vibration tester carry out comprehensive testing to further ensure reliable product quality.
Steel balls are widely used in bearings, hardware, electronics, mechanical equipment, electric power, mining, metallurgy and other fields.
We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
Most importantly, we can customize products to meet the various needs of customers.
