In 2004, Hyundai Steel Corporation acquired Han Baogang, the bankruptcy company in Incheon, and became the world's second largest electric furnace steel plant. The company also owns an electric furnace steel plant in Pohang. Since 2006, Hyundai Steel has invested heavily in the construction of large blast furnaces to produce high-quality plates for the manufacture of automobiles, ships and home appliances. Hyundai Steel is a subsidiary of Hyundai Kia Motors. The group has more than 60 large-scale companies, including Hyundai Motor and Kia Motors assembly plants all over the world, and it also has the world's largest shipyard.
Hyundai Steel Company maintains close cooperation with the subsidiaries of Hyundai Kia Motors Group. The company plans to increase the supply of coil products to the Hyundai-Kia Automotive Group. Hysco, another rolling mill in the group, specializes in cold rolled coils. In April 2011, Hyundai Steel also set up a new No. 3 blast furnace in the Tangjin area. By 2013, Hyundai Steel's crude steel production capacity will reach 24 million tons, of which 12 million tons will be electric furnace steel production capacity. In 2012, Hyundai Group plans to invest US$12 billion at home and abroad, an increase of 16% year-on-year, setting a new high for the Group's annual investment.
The Bank of Korea predicts that South Korea’s GDP will increase by 3.7% in 2012. Rapid growth in Korean steel production capacity has begun to affect the Japanese steel industry. In 2011, Japan’s exports of steel to South Korea decreased, but imports of steel from South Korea increased. At the same time, the devaluation of the won also promoted the growth of South Korea’s export trade. The Japanese steel industry is paying close attention to changes in South Korean steel production in the medium to long term. However, major Asian economies, especially China, will see further growth in crude steel production in 2012 and beyond.
Through investment in the Asian steel industry, Japan's blast furnace steel mills will continue to supply high-quality steel to domestic steel companies and affiliates in Asia and other regions, and even some affiliates in Korea. The establishment of an industrial chain on a global scale, especially in East Asia and Southeast Asia, will ensure that large steel companies in Japan and South Korea have a relatively good market environment. However, the fact is that steel production capacity in Asian countries and regions continues to grow and will pose great challenges to the steel industry in Japan and South Korea.
SDS Plus and SDS Max drill bits can be used for drilling operations in concrete, reinforced concrete, granite and similar materials. SDS-Plus has a drilling diameter of 4mm to 32mm and a drilling depth of 110mm to 1000mm; SDS-Max has a drilling diameter of 12mm to 52mm and a drilling depth of up to 1200mm.
SDS Drill Bits are available with two (properly shaped integral straight edges), three (star arrangement) or four (integral cross arrangement) inserts, made of cemented carbide. They are deeply embedded in the steel head with industrial solder and are characterized by a high degree of mechanical and heat resistance.
SDS Plus and SDS Max Bits should not only be selected based on the diameter of the drilled hole, but also their depth standard. Both of these measures are necessary to maximize productivity.
