If you are purchasing steel balls, you need to seek advice and recommendations from professionals in the steel ball industry. As an industry veteran with over a decade of experience, Kangda Steel Balls is willing to share our knowledge and insights selflessly, providing you with some practical tips to help you avoid unnecessary detours and wasted money.
When purchasing steel balls, it is essential to first clarify your requirements and the intended use. Only after confirming these two points can you select the appropriate type of steel balls for your products. Steel balls are not a simple category; they are classified based on different materials, such as carbon steel balls, bearing steel balls, stainless steel balls, tungsten steel balls, etc. Even within the same material, there are significant differences in price and application based on different grades. For instance, high-grade steel balls like G5, G10, and G16 have high precision and low error, making them suitable for high-quality precision products. On the other hand, grades like G28, G40, G60, G100, G200, G500, and G1000 have larger numbers indicating lower precision and greater error, and are more appropriate for products with lower quality requirements. Additionally, different materials have varying hardness and rust resistance, which are also crucial factors for judgment.
Some customers use the steel balls for grinding and polishing, so you don't need to purchase high-precision ones. Low-grade G1000 can meet the usage requirements and is cheaper. There's no need to buy high-grade ones, which would be a waste of money. Some customers use them for assembling high-end products. In this case, you can't save money and mustn't choose low-grade steel balls just to save a little. It may seem like you've spent less money, but after assembly and use, you'll find that they don't meet the technical requirements. The product might be scrapped, which would increase the product cost and damage your company's reputation. It's not worth it.
If you want high hardness and good wear resistance, then bearing steel balls are suitable for you. If you also need good rust resistance, then 440C material is suitable for you.
If you want something that can be welded, has a relatively cheap price, and does not require rust prevention, you can choose Q235 carbon steel balls without firing. These balls have low hardness and are more firmly welded.
If you want good rust prevention and corrosion resistance, then using medical materials such as 316 or 316L is better. If the rust prevention requirements are not as high and the cost-effectiveness is relatively high, then we recommend using food grade materials such as 304.
In short, different purposes and requirements require different steel balls to be used. It is necessary to clarify this aspect in order to get things done with less money! For over a decade, Kangda Steel Ball has always been committed to catering to customers' needs and urging them to recommend suitable steel balls. Once customers are satisfied, making money is just a side event.
