Sorbite high strength stainless structural steel is a new type of steel developed and named by the Chinese. Combining the merits of high-grade strength, toughness, corrosion resistance, as well as easy welding and cost efficient, the product marks the completion of an innovative step from stainless steel to structural steel.

Sorbite high strength stainless structural steel S600E has an elongation of more than 20% at 600 MPa yield strength, a coefficient of expansion similar to that of carbon steel, greater elasticity modulus than that of carbon steel, and 100 times stronger in neutral salt spray corrosion resistance than that of general carbon steel.

Sorbite high strength stainless structural steel is suitable for all types of buildings in the seismic zone and coastal areas, and is also an ideal choice for new assembly-type buildings.

Zhenzhou Yongtong has collaborated with the China Electric Power Research Institute, the 713 Research Institute of China Shipbuilding Industry Corporation, the MUYUAN Group (an animal husbandry company), Zhengzhou Coal Mining Machinery (Group) Co., Ltd, Naval Engineering Design Bureau, CNPC Tubular Goods Research Institute and other customers.

All customers have given positive feedback after testing the use or actual use of the sorbite high strength stainless structural steel in their fields. Hence, there are broad prospects for further applications for the product.

Earlier this year, the relevant standards of sorbite high strength stainless structural steel were recognized as a R&D project of the Standardization Administration of the People’s Republic of China and other relevant organizations.

The MPI and Zhengzhou Yongtong has jointly set up a special group taking charge of compiling the standards of sorbite high strength stainless structural steel and completed the task. On August 22, 2017, the series of seven standards on sorbite high strength stainless steel was released by the China Special Steel Enterprises Association.

About 200 delegates from relevant research institutes, industrial associations, and government bodies including the Chinese Academy of Engineering, China Iron and Steel Association, China Steel Structure Association, China Metallurgical Association, National Defense Science and Industry Bureau of Henan Province, Henan Provincial Bureau of Quality Supervision, Municipal Committee and municipal government of Gongyi (Henan Province), had participated in Monday’s press conference.
