Introduction

Steel balls are an important basic component, especially precision industrial steel balls, which play a huge role in the development of the national economy. Under certain special conditions, it is usually necessary to use special materials of steel balls to meet the functions in different environments. In fact, some special material steel balls have been widely used in various fields of the national economy, including 9Cr18, 3Cr13 stainless steel, copper, aluminum, titanium alloy steel, agate, glass, ceramic balls, etc. Their promotion and application have not only promoted the development of the steel ball production industry, but also promoted the technological development and technological progress of related industries.

E52100 chrome steel balls are used in the ball and roller bearing industry and various automotive applications. These chrome steel balls have excellent surface quality. Through quenching, they have excellent wear resistance, high hardness and high load carrying capacity.

We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.

Our products enjoy high evaluation and satisfaction among customers. Most importantly, we can customize products to meet the various needs of customers. According to customer requirements, steel balls can be produced in accordance with Chinese standard GB/T 308, international standard ISO 3290, American standard ANSI/ABMA, German standard DIN 5401, Japanese standard JIS B 1501, etc.

Production Process

1. Wire Drawing

Each batch of raw material steel is inspected and classified according to different material (carbon, stainless, chrome), size and quantity, which marked with the Material Cert. The qualified steel comes to the quarantine area; the unqualified will be rejected with a record.

Then the steel is made into different sizes according to the needed requirements.

2. Cold Heading

The raw material certified is worked on high-speed casting machines to cast into different size pieces.

3. Ball Flashing

This step of the production process involves rolling the pieces between discs with concentric grooves to eliminate signs of casting and to increase the precision of the ball.

4. Heat Treatment

Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be achieved with the materials used.

5. Hard Grinding

Successively several careful grinding processes using ceramic grinding wheels give greater dimensional precision and prepare the balls the next, final lapping process.

6. Lapping

This procedure gives the ball a perfectly shiny, compact and defect-free surface, with very low surface roughness, much lower than that required under GB/308-2002

7. Cleaning

Remove the oil stains on the surface of the steel ball , make the steel ball cleaner and brighter.

8. Selecting and Final Inspection

The sorting machines together with the manual detecting and modern testing processes, largely ensures the high quality of our products.

9. Packaging

Pack products according to customer needs.
