The "action plan" proposes to increase the development of non-fossil energy. Accelerate the construction of large-scale wind power photovoltaic bases focusing on deserts, Gobi and deserts. Develop offshore wind power in a reasonable and orderly manner, promote the large-scale development and utilization of ocean energy, and promote the development and utilization of distributed new energy sources.

304L stainless steel: The national standard of this stainless steel is 022Cr19Ni10, and its biggest feature is that it can maintain excellent performance in a low temperature environment above -196 °C. The low temperature impact toughness of 304L is good, and the risk of embrittlement and fracture of the material is relatively small even in a low temperature environment of more than -100°C.

Laser cutting is the use of high energy density laser beam irradiation on the surface of stainless steel, so that the material quickly melt, vaporize or reach the ignition point, while the high-speed airflow will melt or burn the material away to form a cutting slit.

The chromium element forms a chromium-rich protective film on the surface of the 304L stainless steel sheet, which is essential to prevent oxidation and corrosion of the stainless steel. It is because of the existence of this protective film that 304L stainless steel sheet can maintain its original luster and strength under various environmental conditions to prevent rust and corrosion.

Austenitic stainless steel has a high cold work hardening index (0.34 for stainless steel). Austenitic stainless steel is a metastable type, which will undergo phase transformation during deformation and induce martensitic phase. Martensite is relatively brittle and therefore prone to cracking.

A recent study by NIMS and Nagoya University found that in addition to the electromagnetic conversion function, iron-based amorphous alloys can be converted into a "transverse" thermoelectric conversion material through a short heat treatment, converting current and thermal current in an orthogonal direction, which provides new design guidelines for the development of thermoelectric materials.

Stainless steel can be roughly divided into 200 series, 300 series and 400 series three categories, of which 300 series is the most commonly used, 200 series and 400 series is a certain way of 300 series of substitutes, and strictly speaking, 400 series is not called stainless steel, called stainless iron, because it does not contain nickel elements, so magnets can be attracted.

There are also surface spraying processes; Stainless steel spraying and the above coloring treatment is very different in substance, due to the difference in materials, some spray paint may destroy the stainless steel surface oxide layer.
