In late autumn of this year, Hebei Iron and Steel Group Shi Gang company found that Shi Gang's high-purity non quenched and tempered steel products have been widely used in the manufacturing of car hub shafts, connecting rods, crankshafts, steering knuckles, halfshafts, front axles and engine pistons, which are not suitable for human settlements. At the same time, alloy structural steel, guaranteed hardenability structural steel, high-quality carbon structural steel and other products are widely used in BMW Audi motor company, Toyota Motor Company, Hongqi motor company, Dongfeng Motor Company and other well-known automobile enterprises at home and abroad. In late autumn of this year, Hebei Iron and Steel Group Shijiazhuang Iron and steel company found during the inventory harvest that Shijiazhuang Iron and steel can reduce the weight of each vehicle by 4 kg. High purity non quenched and tempered steel products have been widely used in car hub shafts. For equipment manufacturers of recycled plastic granulator, connecting rods, crankshafts, steering knuckles, half shafts, front axles, engine pistons are manufactured. At the same time, alloy structural steels, structural steels that ensure hardenability High quality carbon structural steel and other products are widely used in famous automobile enterprises at home and abroad, such as BMW, Audi, Toyota, Hongqi automobile company, Dongfeng Motor Company, etc

behind the good results in the production and sales of automotive steel at Shijiazhuang Iron and Steel Co., Ltd., is the efforts made by the people of Shijiazhuang Iron and Steel Co., Ltd. to pursue the automotive dream, which has supported the people of Shijiazhuang Iron and Steel Co., Ltd. for more than ten years

reduce oxygen content and open the door to the market

Shijiazhuang Iron and Steel Co., Ltd. is located in Shijiazhuang, the capital of Hebei Province, and its development space is restricted. Therefore, they find another way, do not expand one ton of production capacity, and work hard on the adjustment of variety structure. In the late 1990s, Shijiazhuang Iron and Steel Co., Ltd. took the lead in completing the transformation from general steel to excellent steel. At the beginning of this century, with the maturing of converter smelting technology of high-quality steel in the metallurgical industry, the advantages of high-quality steel of Shijiazhuang steel gradually disappeared. Shi Gang realized that it must adjust its strategic objectives and product positioning, and cultivate its own core technology through product structure adjustment. After extensive research and demonstration, Shijiazhuang Iron and Steel Co., Ltd. has determined the production direction of special steel products focusing on developing five kinds of high-quality carbon structural steel, gear steel, bearing steel, spring steel and alloy structural steel. It takes the automobile industry, which has the most potential, as its goal, and sets itself the grand goal of building a strong enterprise of special steel bars for automobiles

in 2002, Shijiazhuang Iron and steel began to contact Toyota Motor Company. After the first round, Shijiazhuang Iron and steel was tripped by the difficulty of oxygen content in steel. As a stepping stone to reaching a long-term cooperation with Toyota Motor Company, Shijiazhuang Iron and steel took the initiative to reduce the oxygen content in steel from more than 60 ppm to less than 30ppm within one year. To this end, Shijiazhuang Iron and Steel Co., Ltd. invested 40million yuan to reach a technical agreement with Aichi Steel Co., Ltd. of Toyota Motor holding company, invited experts of Aichi Steel Co., Ltd. to consult for 7 times, and sent technicians to Aichi Steel Co., Ltd. to study, so that their technicians and operators learned the essence and significance of Aichi steel. In October, 2003, the oxygen content in the steel of Shijiazhuang Iron and Steel Co., Ltd. fell below 30ppm, and passed the certification of Toyota Motor Company at one stroke

Shi Gang people did not stop at this point, but continued to explore and move forward. Now the oxygen content in the steel supplied by Shi Gang to Toyota Motor Company has fallen below 10ppm, maintaining a stable supply of more than 12000 tons of steel to Toyota Motor Company every year. Since this year, the pass rate of UT flaw detection of S48 and S53 automotive steel supplied by Shijiazhuang steel to Toyota Motor Corporation has been stable at more than 93%, while the pass rate of flaw detection inspection in Toyota Motor Corporation has remained 100% for more than two consecutive years

the steadily improved product quality of Shijiazhuang steel has gradually been unanimously recognized by Japanese auto manufacturers. Shijiazhuang steel products are gradually being used to produce the core parts of Japanese cars, including gear boxes and engines (previously imported from Japan)

authoritative certification helps market development

in 2009, Shijiazhuang Iron and Steel Co., Ltd. won three series of international authoritative certification at one go, further opening the door to the international market. One of them is the TS16949 certification issued by French BVQI company, which is mainly aimed at the foreign auto parts industry. With this exclusion method: fill the fuel tank of the experimental machine with a permit, the export products of Shijiazhuang Iron and steel are qualified to be used in international famous cars such as Renault, Peugeot and Citroen of France

in the same year, Shijiazhuang Iron and Steel Co., Ltd. received 156 more rigorous second-party audits, which were mainly concentrated in Japan, South Korea, the United States and other countries, including Japan's NSK automobile company and South Korea's Hyundai Automobile Company, which marked that Shijiazhuang Iron and Steel Co., Ltd. has entered the fast lane of special steel production

on April 28, 2011, Shijiazhuang Iron and steel signed a sales order with a processing base in China of German Mercedes Benz and BMW. So far, more than 10000 tons of steel have been supplied to Mercedes Benz and BMW, indicating that the high-quality strategy of special steel has taken a decisive step

in 2012, under the extremely severe situation of the steel market, Shijiazhuang Iron and Steel Co., Ltd. achieved remarkable results in structural adjustment, developed 35 new products throughout the year, achieved a sales volume of 85000 tons, and created a cumulative benefit of 11.67 million yuan. Due to the successful development of scm20, 20mncr5hh, 30MnVS and other varieties, Shijiazhuang Iron and Steel Co., Ltd. has taken the step of moving from commercial vehicles to passenger vehicles

at the beginning of this year, Shijiazhuang Iron and Steel Co., Ltd. proposed to carry out the annual activity of quality construction and unswervingly follow the development path of specialization, quality and characteristics. This can be used not only as a guide for the future development of Shijiazhuang steel, but also as a summary of the development of Shijiazhuang steel in the past 10 years

since then, Shijiazhuang Iron and steel began to provide ZF (which produces gear boxes and other key components for German cars) with gear steel and free cutting non quenched and tempered steel samples of multiple specifications. It is expected that the parts produced with these steels will soon appear on German passenger cars

when talking about the future of Shijiazhuang Iron and steel automobile dream, chairman Wang Liping said: there is a long way to go, full of hope
