9Cr18 stainless steel ball is a spherical iron-iron wear-resistant body which is mainly composed of carbon, chromium, manganese, molybdenum and the like, and is formed by forging, spinning, rolling, grinding and casting. It is crushed today. The most important part of the industrial and bearing industry. Steel balls are important basic components, especially precision industrial steel balls play a huge role in the development of the national economy. Under special conditions, steel balls of special materials are often required to perform the functions required in different environments. In fact, some special material steel balls have been widely used in various fields of the national economy, including stainless steel, copper, aluminum, titanium alloy steel and agate, glass, ceramic balls and so on. Their promotion and application not only promote the development of the steel ball production industry, but also promote the technological development and technological progress of related industries.

The 9Cr18 stainless steel ball is the most important part of the bearing and the most used rolling element in the bearing industry. Its quality directly affects the quality of the bearing. The post-process of steel ball production, namely automatic cleaning of steel balls, automatic appearance inspection (automatic rejection of non-conforming products), automatic rust prevention, counting and packaging, are the key factors affecting the quality of steel balls. The appearance inspection of steel balls is an indispensable process in the processing of steel balls. The appearance inspection of steel balls mainly includes the detection of surface scratches, rust, surface spots and the like.

Can be used as a damper on a skyscraper. The steel ball is very hard. It is important in some small parts. The quality of steel balls is affected by many aspects:

1 Material density effect: steel ball, cast iron ball, alloy steel ball, etc., the density of different materials is different, the density of steel is larger than that of cast iron, and the alloy steel is different depending on the density and content of the main alloying elements.

2 steel ball manufacturing method: rolling and forging steel balls have dense structure, so the density is large, the cast cast steel balls, cast iron balls or cast alloy balls are not dense, even have pores, so the density is small. some.

3 Metallographic influence of steel ball: The density of different crystal structures such as martensite, austenite, bainite and ferrite is also different, which also affects the crystal fineness.

4 chemical composition factors: steel ball products due to the chemical components such as iron, carbon, chromium, manganese, sulfur, phosphorus and other components, the steel ball hardness, impact wear has varying degrees of impact, in general, When the amount of chromium is large, the steel ball has high wear resistance. Good quality!

9Cr18 steel martensitic stainless steel contains carbon and chromium. It is for this reason that it is highly prone to form uneven carbides in steel and affect the properties of steel. This requires attention during production. Due to the high C and Cr in the steel, the steel has high strength, and also has stainless steel and corrosion resistance. It is generally used for the production of stainless or weak resistant medium and resistant to oxidizing acid, organic acid and Corrosive balls such as salt, bearings, high quality knife and scissors, surgical tools, abrasion resistant parts, etc.

Due to the high carbon content in the steel, it has high hardness and wear resistance after quenching, and has excellent rust and corrosion resistance in the atmosphere, water and some aqueous solutions of acids and salts, and when this steel More obvious when containing molybdenum. The weldability of this steel is not good and should not be used as a welding material. Used in the manufacture of slicing mechanical cutting tools, shearing tools, surgical blades, bearings, valve plates and other parts subject to high friction and working under corrosive media conditions.
