Sany's independent research and development steel plate through international verification        

Recently, the SG700E and NM400 steel plates successfully developed by Sany subsidiary Zhong Yuan new material Co., Ltd. have been tested and certified by international authoritative testing institutions.

The toughness of the new steel plate is more than 10% higher than that of the same grade steel plate. It is understood that the source is currently only able to provide the thin NM400 wear-resistant steel plate (thickness = 5mm) of the company.

In 2013, China began to develop NM400 wear-resistant steel plate. Through a series of technological innovation and technological breakthrough, successful development and mass investment in the market.

"This plate is mainly used for wear resistance of conditions, such as excavator digging screed plate, paver bucket on the other." 31, Zhang Jianping, executive vice president of China Resources, said that NM400 wear-resistant steel plate has been widely used in industry, but there is always a problem of welding cracking and the bottleneck of performance stability and smoothness.

In view of the technical difficulties, the R & D team went deep into the production site, made a lot of comparative test analysis and process improvement, and finally solved the problem of welding cracking after the adoption of the new leveling technology, and made significant technological breakthroughs.

Since 2004, the 31 source has been aiming at the market of high strength and wear-resistant steel. After more than ten years of research and development and trial production, the high strength steel plate required for SG700E, SG1000, SYG960 and other engineering machinery products has been developed.

At the same time, the SG series of high strength steel plates are also promoted. The low temperature impact performance of this series of steel plates is greatly improved, and the flatness of the steel plate reaches the international standard. In particular, the comprehensive performance of SG700E high strength steel plate has surpassed that of the international brand. The toughness of 70KG and 100KG high strength steel plate has increased by more than 10% compared with the same grade steel plate abroad.

The steel plate after the process is improved will improve the competitiveness of the main products of the group. This means that the central source is in the forefront of high strength and wear-resistant materials in the world. Not only that, the 31 group of products manufactured by steel plate in the use of higher strength, its product advantages are self-evident, that will add a new boost to the market.
