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.

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.

Solid Chrome Steel Balls

Well-Made

Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each steel ball.

High Hardness

Ball hardness is controlled within the 60-63 HRC range as measured on parallel flat surfaces.

Wide Applications

Bearing balls are used in automotive applications, for semi-precision bearings, and in commercial applications.

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.

Established in 2006, Xi'an Machinery & Engineering Import & Export Co.,Ltd.（XMEC) is the successor to Shaanxi Marine and Engineering Import & Export Co., Ltd., which is specialized in importing & exporting mechanical and electrical products, complete equipment, various kinds of vessels and ships, marine equipment and port machinery, electronic and electric products, instruments and meters, minerals and metals, light industrial products, etc. XMEC also engages in different trading activities such as import and export of techniques and overseas project contracting.
