Description
High carbon chromium bearing steel is a high carbon alloy steel containing 1.30 to 1.65% chromium. Its characteristics are more uniform and stable structure after heat treatment, high hardness, good uniformity, good wear resistance, high contact fatigue strength, good dimensional stability and corrosion resistance after annealing, good cutting performance, and relatively cheap price. . This steel can meet bearing requirements under normal working conditions.
Weldability
Because this material has 1% carbon, it does not weld well. It can be resistance welded with difficulty. It can be soft soldered with a high tin solder using an acid flux. It can be silver soldered or brazed; but the heat will cause distortion of the ball and a loss of hardness. For light load applications, the ball can be attached with an adhesive such as epoxy. When adhesive bounding is used, an area on the ball should be roughed up by etching or abrasive blasting. The area should be thoroughly cleaned.
Metal balls are used mainly in precision ball bearing designs, roller applications and other demanding industrial applications. The surface is fine finished and hardened for a high load capacity.
After more than 20 years of continuous efforts and development, our company has become one of China's leading equipment suppliers, and can provide high-precision steel balls with complete specifications. The steel ball has high precision, good surface smoothness, standard hardness and excellent wear resistance. Our products have been widely exported to Europe, America, Japan, Korea, Central Asia and Southeast Asia.
Chrome steel and other metal balls are manufactured using the following processes
- Forging and cold heading. Rough ball shapes are forged from bar stock material.
- Deflashing. Rough machining or soft grinding removes the forge flashing.
- Heat treatment. Balls are heat treated based on technical specifications in a controlled process.
- Finishing. Stainless steel balls skip this step. Other steel balls may be hardened using heat treatments, quenching, or other tempering methods.
- Hard Grinding. The steel balls are ground to remove nicks and imperfections.
- Lapping. A controlled mechanical sanding/polishing process brings the balls into the intended design, grade dimensions, and spherical accuracy within 1/1,000,000 of an inch.
- Inspection & Packaging. Lubricant or rust-preventive is applied as a final step before the steel balls are inspected and packaged.
We also offer a range of grades of steel, such as AISI 52100 or 100Cr6. So pick the material and grade that meets your needs precisely.
