Recently, Hudong-Zhonghua Shipbuilding (Group) Co., Ltd. (hereinafter referred to as Hudong-Zhonghua) sent a letter of thanks to Taiyuan Iron and Steel Co., Ltd., on the first 49,000-ton chemical tanker “Bao Olyan” contracted by Hudong-Zhonghua. On the occasion of the smooth delivery, thank TISCO Stainless Steel for providing high-quality duplex stainless steel plates.
Since 2017, TISCO‘s marketing and technical personnel have intervened in advance to continue to follow up the project, but foreign shipowners are cautious about domestic materials and require the use of imported materials. Under this circumstance, TISCO cooperated with Hudong Zhonghua to conduct in-depth exchanges with the shipowner for many times. Based on a detailed understanding of customer needs, it optimized and improved the product process plan in a personalized way, which further effectively guaranteed the shipowner. Most concerned about quality stability issues, and proposed to take advantage of the extended processing advantages of Daming Heavy Industries under “dismantling-production-processing-distribution”. With the joint efforts of all parties, the shipowner’s worries were finally eliminated and the company agreed to use TISCO materials.
In July 2017, TISCO won a fierce bidding with top international companies and signed a contract with Hudong Zhonghua for the supply of duplex stainless steel for four 49,000-ton chemical tankers. In August 2018, Hudong Zhonghua and TISCO Signed a supply contract for duplex stainless steel for two 38,000-ton chemical tankers. Up to now, all 15,000 tons of duplex stainless steel materials for six chemical tankers have been delivered, and the excellent product quality and perfect solutions have been fully recognized by the shipowner.
TISCO is the first company in my country to develop and produce duplex stainless steel. In 2007, it produced the first domestic-made duplex stainless steel plate for chemical ships, which successfully replaced imports and filled the domestic gap.
In more than ten years, TISCO has completed the production and supply of duplex stainless steel for 49 chemical tankers at home and abroad. According to the person in charge of duplex stainless steel research and development at Taiyuan Iron and Steel, due to different hull structures, the requirements for material technology of super-large chemical tankers have increased by more than one order. In 2016, Taiyuan Iron and Steel’s duplex stainless steel was successfully used for 33,000 tons of chemicals for the first time The construction of the ship and its application to a 10,000-ton chemical tanker can be said to be a milestone in the development of domestic duplex stainless steel materials. The application of the 49,000-ton chemical tanker this time fully demonstrates that TISCO’s duplex stainless steel material has the strength on par with international advanced enterprises in terms of process technology and product quality, which is of great significance. In the next step, we will continue to keep a close eye on the development trend of advanced steel materials, continue to develop new products, and provide strong support for the construction of a manufacturing power.
