PRODUCT DETAILS

Our company produces forged steel balls and hot-rolled steel balls in accordance with YB/T091-2005 forged ball standards, with an annual production capacity of 100000 tons. Exported to over 30 countries and regions, widely praised by customers.
We have advanced production equipment and comprehensive testing methods, equipped with a high-quality professional team, and have the ability to independently research and develop new products. We have successively developed and successfully launched 60 manganese forged steel balls, B2 material forged steel balls, and B4 material forged steel balls to the market. Especially the wear-resistant steel balls made of B2 and B4 materials we produce have been recognized by many countries, with high internal hardness and low wear, reaching the highest international quality level.
Our automated ball rolling mill production line is the most advanced hot rolled steel ball production equipment in China, improving the quality of steel balls and significantly increasing production efficiency, resulting in our steel ball production reaching over 100000 tons
Our company can produce steel balls with various compositions and hardness according to customer requirements, and the most commonly used ones are as follows:
