    - Expecting to sell more materials for premium consumer electronics and electric vehicle motors

    POSCO firmly established the system for producing the highest-grade non-oriented silicon steel, the core material for environmentally-friendly electric vehicle drive motors and world premium consumer electronics.


    On February 20, POSCO held a ceremony to celebrate the completion of the non-oriented silicon steel production capacity expansion project at Pohang Steel Works. POSCO CEO Ohjoon Kwon, and 100 officials from POSCO affiliates such as POSCO E&C and POSCO ICT, equipment suppliers and clients attended the ceremony.

    As of now, POSCO's top-grade Non-Oriented silicon steel (Hyper NO) production has been increased from 80,000 to 160,000 tons, equivalent to a quantity that can be supplied for approximately 2.6 million electric vehicle drive motor cores.  


    Electrical steel sheets are made by adding 1~4% silicon to iron. They possess excellent electromagnetic properties, and are divided into Grain Oriented silicon steel (GO) and Non-Oriented silicon steel (NO) depending on the crystallographic direction of the metal. They consist of high-grade steel material. GO is used as a material for the core of stators like transformers, whereas NO is used as a material for rotors like motors and generators as it has almost the same electromagnetic properties in all directions.


    This capacity expansion project increased the production of the top-grade NO, used as the core of high-efficiency premium consumer electronics and electric vehicles. It is an environmentally-friendly material that follows the trends of the times, e.g. energy saving and reduction of CO2 emissions.


    In a bid to quickly secure future competiveness in response to the expansion of the high-efficiency premium consumer electronics and electric vehicle market, POSCO has conducted improvement projects since 2015 over a period of 2 years and 9 months, such as improvement of APL (Annealing & Pickling Line) and ACL (Annealing & Coating Line), and construction of ZRM (Sendzimir Reverse Mill), capable of producing 0.15mm steel sheets. In particular, the 0.15mm electrical steel sheets, produced as a result of this improvement project, will contribute to minimizing power loss of customers' end products.


    ▶ On February 20, POSCO CEO Ohjoon Kwon wrote 'Realizing World-best Technology and Best Competitiveness in Hyper NO' at the completion ceremony for the highest-quality non-oriented silicon steel capacity enhancement project, and encouraged employees.


    As production of environmentally-friendly cars and high-efficiency consumer electronics has been increasing recently due to global environmental issues, it seems that the demand for top-grade electrical steel sheets, the materials for core parts, will rise from last year's 800,000 tons to more than 1 million tons in 2020. POSCO expects to increase its market share by developing customized products for individual electric vehicle manufacturers and providing services, and see its profitability improve due to the increased sales of top-grade NO, thanks to its supply of premium-grade materials for high-efficiency motors as the quality of consumer electronics is improving at home and abroad.


    Meanwhile, this project, which required investment of KRW 124.1 billion in total, greatly contributed to invigorating the local economy as a total of 200,000 construction workers were employed during the construction period. Also, as the construction period was reduced by 3 months, and equipment was recycled and the design was optimized, the total investment cost was reduced by 6.5%.  


    POSCO CEO Ohjoon Kwon said, "The completion of this project has now enabled us to proactively meet market needs due to the increasing demands for environmentally-friendly cars and high-efficiency premium consumer electronics. I sincerely hope that you will make efforts to deliver top-quality electrical steel sheets to customers by stably operating the system and working hard to develop technologies so that we can lead the premium market with quality and technology."  


    As it successfully completed this high-grade material capacity expansion project, installed additional equipment, and thus built a stable production system, POSCO expects to proactively respond to the domestic and overseas demands for domestic non-oriented silicon steel.
