Looking for high quality G40 440C Stainless Steel Ball? Welcome to choose Condar, a professional steel ball manufacturer from China. We integrate production and sales, have many years of export experience, and our cooperation countries are all over the European, American and Southeast Asian markets. We look forward to establishing a long-term cooperative relationship with you.
Condar's G40 440C stainless steel ball is a steel ball product suitable for use in multiple fields. The material is 440/440C stainless steel, which contains carbon. Through a fine and strict processing process, it produces a steel ball with reliable strength and meets the G40 standard.
Product Features
1. High hardness: The hardness of 440/440C stainless steel balls is relatively high, which is stronger than the lower hardness of 304 and 316 stainless steel balls, and is also better than 420 stainless steel balls in performance, and can perform better under higher pressure working conditions.
2. Rust resistance: 440/440C stainless steel itself has good rust resistance. The steel ball also contains chromium, which can form a dense oxide film and is more adaptable to more severe and complex use scenarios.
3. Wide range of applications: Whether it is hardware, auto parts or various precision instruments and meters, G40 440C stainless steel balls can provide precise and high-strength resistance. Deep-sea bearings can also use this steel ball, which has good rust and corrosion resistance and sufficient strength. It can also be used in areas where safety is more important, such as food grinding and medical equipment, without the risk of pollution.
