The requirements of the petrochemical industry for stainless steel mainly include corrosion resistance, including chloride, sulfide and other salt corrosion; high temperature resistance and low temperature resistance. The stainless steel used for crude oil exploration and development requires resistance to carbon dioxide and hydrogen sulfide corrosion.
High temperature alloy is a key material for high temperature parts of aerospace and aviation manufacturing engines. It is mainly used to manufacture combustion chambers, turbine blades, guide blades, compressors and turbine disks, turbine casings and other parts. The operating temperature range is 600 ℃ -1200 ℃. The stress and environmental conditions vary with the parts where the parts are used. There are strict requirements on the mechanical, physical and chemical properties of the alloy, which are the decisive factors for the performance, reliability and life of the engine . Therefore, superalloys are one of the key research projects in the aerospace and defense fields of developed countries.
Energy and Chemical
The energy industry is the basic industry for the development of the national economy and the improvement of the people's living standards. In the past 20 years, with the rapid development of China's national economy and the continuous improvement of people's living standards, the demand for energy has continued to increase, and energy tensions have emerged. With the development of the energy industry, the energy equipment manufacturing industry has also developed rapidly, and the demand for metal and steel materials is also increasing, and it is constantly developing in the direction of high parameters, large capacity, and high efficiency.
