Chinese steel giant Baowu announced that after nearly half a year of testing & technical verification, a high-strength hot rolled steel substrate for home appliances BJDX02 has been developed by BaoSteel and its downstream metal material processing units. BaoSteel has started commercial production of BJDX02 and supplies. Some leading Chinese home appliance enterprises put forward new requirements for the strength and thickness of refrigerator side and back plate materials in 2021 end to reduce the thickness by at least 10% while increasing the strength by more than 10%. Baosteel's technical service team took the lead in organizing the project evaluation and carried out multi-rounds of optimization in material composition design and hot rolling process, with clients’ technical processing capability taken into account. Through repeated trial production of sample parts, and with continuous adjustment of both the hot-rolling process in Baosteel and the processing technology of the clients, the final product quality has been stabilized, and the performance and surface quality fully met the requirements. At present, Baosteel BJDX02 high-strength steel for household appliances as well as its processing procedures by clients has been finalized, and can later be supplied stably in batches.
