Independent research and development of high-strength stainless structural steel S600E released in Beijing

On December 11th, the “Sormite High-Strength Stainless Steel S600E Press Conference” jointly sponsored by China Special Steel Enterprise Association, Metallurgical Industry Planning and Research Institute and Zhengzhou Yongtong Special Steel Co., Ltd. was held in Beijing. A special steel material independently developed and named by our team, the Soxite high-strength stainless structural steel S600E (hereinafter referred to as “S600E”) was officially announced at the press conference.

Liu Zhenjiang, Party Secretary of China Iron and Steel Association, and Sun Shufang, Mayor of Gongyi City, Henan Province attended the press conference and delivered speeches. Yin Ruizhen, deputy director of the former Ministry of Metallurgical Industry and academician of the Chinese Academy of Engineering, and Li Helin, academician of the Chinese Academy of Engineering, spoke at the meeting.

Yin Ruiqi said that S600E is a low-cost, cost-effective new steel grade with high strength, good corrosion resistance, excellent welding performance and heat resistance. It can be widely used in construction of offshore bridges, offshore oil platform construction, marine engineering construction, ship construction, power transmission engineering, marine transportation facilities, etc., and many engineering construction fields and photovoltaic projects with high requirements for corrosion resistance, strength and weldability. , certain areas of wind power engineering and new energy construction.

Li Helin said that the S600E is an invention in which the Chinese have completely independent intellectual property rights. This steel grade greatly enhances the strength of traditional stainless steel and completes the leap of stainless steel to structural steel. It is a brand new Sorbite stainless steel. There is structural steel in the stainless steel and stainless steel in the structural steel. "S600E has been tested as a new microcrystalline material by Columbia University, China Shipbuilding Heavy Industry 725 and other units. It is a kind of super steel." Li Helin said that China needs more good steel for development, which is our move to a steel power. Required.

At the press conference, Li Xin, Dean of the Metallurgical Industry Planning and Research Institute, wrote a keynote report entitled "The Status Quo, Trends and Suggestions for the Development of China's Stainless Steel Industry". Wang Huaishi, Secretary General of China Special Steel Enterprise Association, read "Soxhlet" at the meeting. The implementation of the implementation standard for the series of high-strength stainless steel structural steel standards.

Wang Ping, vice president and chief engineer of Nickel Resources International Holdings Co., Ltd., gave a detailed introduction to the development and application of high-strength stainless steel structural steel. Lu Qingtian of the Naval Engineering Design and Research Institute, Yang Jianping, former vice president of China Electric Power Research Institute, and Qin Jun, deputy general manager of Makino Food Co., Ltd., respectively introduced the high-strength stainless steel structural steel in the marine engineering, power tower, and breeding project. Test and application situation.

After Song Wenzhou, a director of Zhengzhou Yongtong Special Steel Co., Ltd., read a congratulatory letter, Dong Shutong, chairman of Zhengzhou Yongtong Special Steel Co., Ltd., thanked the leaders and experts who have long supported and cared for the development of Yongtong special steel and Soxhlet high-strength stainless steel. The press conference was hosted by Xiao Bangguo, vice president of the Metallurgical Industry Planning and Research Institute.

The reporter learned from the press conference that S in S600E refers to sorbite steel, 600 refers to its yield strength of 600 MPa, and E refers to its seismic performance. That is to say, S600E has an elongation of more than 20%, a coefficient of expansion similar to that of carbon steel, a modulus of elasticity greater than that of carbon steel, and a corrosion resistance of neutral salt spray at a yield strength of 600 MPa, which is more than 100 times that of ordinary carbon steel. Excellent performance. This steel is especially suitable for use in seismic belts and various types of buildings in coastal areas. It is an ideal choice for new assembly buildings. On August 22, 2017, the China Special Steel Enterprise Association's "Sorfite High-Strength Stainless Structural Steel" series of group standards (seven items) was officially released.

At present, the Sorbite high-strength stainless steel has been well received by users such as China Electric Power Research Institute, CSIC 713, Makino, Zhengzhou Coal Mine Machinery Manufacturing Group, Naval Engineering Design and Research Bureau, and China Petroleum Pipe Research Institute. broad.
