On December 28, 2012, the Shaanxi Machinery Industry Association was commissioned by the Shaanxi Provincial Department of Industry and Information Technology to organize the 12JS90, 12JS65, and the latest research and development of the Fast Design Institute of Xi’an Automobile Product Quality Inspection Station, Chang’an University, and Shaanxi Automobile Group. five series of new products 7DS95,6DS240T transmission and all-aluminum case and so the provincial appraisal. The deputy general managers of the company group, Wang Fengbo, Wang Shunli, and Ma Xuyao ​​attended the appraisal meeting. The responsible persons and technicians of the relevant units attended the appraisal meeting. Experts attending the meeting listened in detail to the development report, product inspection report and user usage report of the five series transmission new products such as the 12JS90; reviewed product and on-site production conditions; reviewed product design drawings and technical documents.

Alloy pipe is a kind of seamless Steel Pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe, so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels.
