After many years of research and development, Jiuquan Steel is rolling out high-end stainless steel intended for electronic products. So a long way, "Jiugang Made" can possibly be branded on high-end cell phones, reflecting fashion and famous brands. In today's fast-paced existence, electronic products with large facial value, good touch and good signal are an increasing number of popular with consumers. Based on the actual demand, Jiugang thought he would "eat crabs first", concentrating its superior durability on tackling technical problems for instance purity and permeability 1 by 1. It took the head in developing ultra-pure anti-electromagnetic shielding austenitic steel for high-end electronic products and solutions in China, which was successfully applied within the manufacture of well-known cell phones and became the chosen domestic supplier of International high-end cell phone manufacturers. In November 2016, following your international high-end mobile phone manufacturer technical team been to Jiuquan Iron and Precious metal Co.,Ltd. and set up a preliminary cooperation motive, Jiuquan Iron and Aluminum Co.,Ltd. set up an investigation and development team, technicians desired standards and documents, and inspected and analyzed ordinary 316L metal. According to the performance indicators proposed from the manufacturer, the main focus is on purity as well as permeability of molten steel, aiming to seize the means and win trust. After defining the idea of research and development, technicians analyze the principle factors affecting the residual ferrite content and find out the suitable composition and distribution ratio of new austenitic stainless; study the smelting strategy of pure steel to reduce the number and size of non-metallic inclusions; optimize the hot working process in order to avoid micro-cracks and peeling blemishes of high alloy subject material austenitic stainless steel in the operation of heating and scorching rolling; Optimize the temps curve of hot-wire sound solution treatment, control this grain size, and acquire good plastic toughness index chart. The work hardening curve of these kinds of steel can be received through experiments to greater control the hardening solidity index. From technical arrangement to order delivery, around only 2 months, the 1st 100 tons of ultra-pure anti-electronic shielding austenitic s / s developed and produced simply by Jiuquan Iron and Precious metal Co. reached the client's hands smoothly. The test results show the chemical composition and mechanical properties in the product meet the conditions of American Standard, as well as the permeability, inclusion control level and also forming performance meet what's needed of the industry. After a little trial production, Jiuquan Straightener and Steel Co. has become promoted as a experienced supplier of international high-end phone manufacturers. The R&D team made further efforts to form the process control tips of ultra-pure anti-electronic protecting austenitic stainless steelproduction, and also the key technologies of smelting, very hot rolling, annealing, pickling, cold work hardening and other processes, and realized the particular mass industrial production.https://www.steel-profile.com/Stainless-steel-wire-pl6493226.html 201911ld
