Bearing Steel 

Since the development of bearing steel in 2003, NISCO’s technology level and product level have been greatly improved. High carbon chromium bearing steel successively won the "Gold Cup of Metallurgical Product Quality" from China Iron and Steel Association and " Nanjing Famous-brand Product ". The production volume also jumped over 250,000 tons now, which covers more than 8% of the market. At present, NISCO’s bearing steel products do meet the needs of different class of users.

Mainly used for manufacturing the rolling part (ball, roller, needle) of rolling bearings and the bearing ring, also can be used to make tools, such as dies, measuring tools, screw tap.

High-pressure Boiler Tube Blank Steel

NISCO started developing the high-pressure boiler tube blank steel in the year of 2006. After several years of hard-working, NISCO has formed a mature production line of high pressure boiler tube blank steel, which brings NISCO into the leading part in terms of market share in China. In 2010, sales volume of high pressure boiler tube blank steel was 176,000 tons. In 2011, the sales volume of only T series of tube blank steel reached 56,000 tons, among which, the sales volume of T91 (ultra) super critical boiler tube blank steel reached 13,000 tons, which makes NISCO one of the main  suppliers in the boiler tube blank steel market.

NISCO has always taken customer satisfaction as its mission during high pressure product production. After many times of quality research, NISCO has solved a series of technical problems in the smelting, casting, rolling processes, thus its products boast some characteristics like high purity, strict control of chemical composition, and good surface quality. The products have passed the company certificates of Harbin Boiler Company Limited, Dongfang Boiler Group Co., Ltd, and are widely welcomed and approved by other large-scale boiler tube production enterprises in China.
