Stainless steel is an excellent green building material with high strength, corrosion resistance, long service life and architectural aesthetics. The International Nickel Institute once pointed out that stainless steel can be 100% recyclable and pollution-free, and truly meet the requirements of green, low-carbon and sustainable economic development.

Advanced rail transit mainly includes high-speed railways, heavy-haul railways, urban subways and intercity rail transit. The main directions for the development of advanced rail transit are high-speed, high-efficiency, safety, comfort (low noise, low vibration), longevity, energy saving and emission reduction, and greening. The requirements for steel are high strength and high toughness, wear resistance, rust resistance, high temperature resistance, and excellent manufacturing process, and stainless steel can play an important role in many of the above requirements. The advantages of stainless steel and its products applied to rolling stock are very obvious.

The first performance of silicon steel sheet: The iron loss of silicon steel sheet is required to be low. The low iron loss of the silicon steel sheet is an important indicator of the quality of the silicon steel sheet. The iron loss of the silicon steel sheet is determined according to the different grades of the silicon steel sheet. The higher the grade is, the lower the iron loss value will be.

The pattern of the earliest stainless steel checker plate is horizontal and vertical stripes. In the following 20-30 years, after continuous experiments and improvements, researchers designed patterns with better slip resistance, and promoted and applied them on a large scale. In recent years, the use of stainless steel checker plate has been constantly innovating, breaking through and changing. The applicable industries and product models are also increasing, and the speed of product replacement is also more frequent.

When buying a watch, many watches with metal straps usually indicate that the strap is 316 stainless steel or 316L stainless steel. Whether it is 316 stainless steel or 316L stainless steel, or other grade, it is only the grade of stainless steel material. At present, the grade of stainless steel materials used in watches are mainly 304 and 316, and the comprehensive performance of 316 is the most superior, so the price is slightly higher.

Hunan Hongwang, as the first silicon steel project in the strategic layout of Hongwang Group, is based in Central South, relying on the long-term strategic partnership with LY Steel, and builds a high-magnetic-inductance, high-grade-silicon-steel and intelligent plant with an annual output of 960,000 tons according to low-carbon and green standards, to meet the growing demand for high magnetic induction and high grade silicon steel in downstream industries such as automobiles, home appliances, and micro-motors.

At the beginning of 2020, the cold winter of the whole foreign trade industry came with the epidemic.Vega Huang, who has been in the foreign trade business for more than two years, like many foreign trade counterparts, is no longer active in the face of the cold and quiet market. Until June of the same year, the domestic epidemic was basically under control. The dormant seed sensed the temperature of the outside world and began to wake up.
