Introduction
Chromium (GCr15SiMn, 100CrSiMn6-4, SUJ3) steel ball is a kind of high carbon chromium bearing steel with low alloy content. The high-precision chromium steel ball contains chromium and has excellent surface quality and high bearing capacity due to being quenched.Throughout the manufacturing process, statistical process control can ensure tolerance accuracy, good surface finish and consistent high quality.
The full name of bearing steel is rolling bearing steel. It has high compressive strength and anti-fatigue performance, high hardness, high wear resistance and certain toughness, good hardenability, and extremely strict control of sulfur and phosphorus. It is a high-grade high-quality steel. Make cold work mold steel. Specific gravity: 7.81.
GCr15SiMn bearing steel has higher wear resistance and hardenability than GCr15, medium cold working plastic deformation, poor weldability, sensitive to white spot formation, and temper brittleness during heat treatment. Used to manufacture ferrules with wall thickness> 12mm and outer diameter ≥ 250mm; steel balls with a diameter of 50.8-203.2 and rollers with a diameter> 22mm; in addition, it can also be used as other mechanical parts that require high hardness and high wear resistance, such as rolls. Spiral gauge etc.
Chrome steel ball, as the main part of bearing, are being widely used on the application like automotive industry, automobile, instruments, heavy machinery, engineering machinery and rolling mill machinery. etc.
We mainly produce chromium steel with a size of 7-82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
The ball has high precision, good surface smoothness, standard hardness and excellent wear resistance. Our products have been widely exported to Europe, America, Japan, Korea and so on.
In addition, the company has advanced production equipment and complete testing equipment, including low-speed cold heads, high-speed cold heads, flashing machines, ball mills, grinders and heat treatment devices.
Through comprehensive testing technology, reliable product quality can be further ensured. Through Rockwell instrument, electronic compression tester, optical microscope, metallographic microscope, appearance profiler, laser surface roughness tester, automatic appearance tester and steel ball vibration tester for testing.
