On January 25, RST330 hot-rolled pickling steel independently developed by WISCO for enamel tank of water heater got certified by one of domestic giants in household appliance industry, that is, GREE Electric Appliances Group Co., LTD, Zhuhai. It is another majorbreakthrough made by WISCO in the market of high-end household appliance steel after passing the certification of Haier , Qingdao in 2012.

GREE Group owns three different production lines with various facilities in Zhuhai, Hefei, Wuhan respectively. Because the facilities used by GREE have more limited adaptability to the steel strength compared to those used by Haier, the higher quality of steel is required by GREE, which also causes enormous difficulties for RST33l steel to meet the requirements of three different production lines. Associating with the production, sales and research and development staff, the project team of WISCO research institute optimized the steel components and processes through a large number of laboratory tests and trial-productions, improved the qualified rates of products from previous 70% up to 95%, obtained high recognition and successfully got certified by GREE Group.

The hot-rolled pickling enamel steel that is superior to the stainless steel tank in usability for its longer service life and higher security is a kind of important material enjoying a wide market for replacing the imported cold-rolled enamel steel plate and stainless steel tank to upgrade and update the relative products. It is reported that GREE Group will build the production line in Wuhan into the largest production base of air-source water heater in China. The successful certification of RST330 steel by GREE Group established a solid foundation for WISCO to expand the market of high-end household appliance steel.
