In response to Premier Li Keqiang's call to crack down on the war of China's manufacturing industry, SG-GITANE,quickly established a research team composed of six technicians in January 2017 to independently develop and produce ball socket materials for ball point pen heads. Based on the study of more than 20 technical indexes of ultra-free cutting materials, such as chemical composition, ultra easy cutting performance and production requirements of pen factory, they have successively overcome six technical problems, such as precise smelting of micro alloy composition, easy cutting control of cold drawn steel wire, and increase of corrosion and wear resistance of materials. They have explored and mastered the key technology of material preparation and summarized the smelting and rolling process of materials, And in more than half a year, through three stages and six rounds of trial production by two working areas, we have successfully developed the ultra-free cutting stainless steel for ball socket body of ball point pen head. This product is one of our flagship products, which is widely used in various stationery. The product has stable performance, easy cutting, excellent quality, good strength and extensibility, no environmental pollution, and is widely used at home and abroad Due to its high cost performance and high market share at home and abroad, ballpoint pen manufacturers have gradually replaced many domestic and foreign products in recent years. Our company also provides customized services for similar products. Its technology and product quality have reached the international advanced level

In the expert group appraisal,SG-GITANE ultra-free cutting stainless steel material for ball point pen head" has been highly praised by authoritative experts in the industry. Dong Han, vice president of General Institute of Steel Research of China Steel Research Group, believes: SG-GITANE is the best wire drawing enterprise in China. It works conscientiously and actively, does not flinch in the face of difficulties, meets difficulties and develops roundly The super free cutting stainless steel material for ball pen head has reached the international advanced level in consistency and stability.
