On the morning of October 13, 2019 Zhengzhou International Marathon gave opening shoots in the Ruyi Lake, CBD, Zhengdong New District. This event was the “Running China” series of activities for the 70th anniversary of the Fouding of the People's Republic of China. There were 26000 participants astm a573 standard from 32 countries and regions including China, the United States, Italy, Russia, Spain, Ethiopia, and Kenya to witness the vicissitudes of "International Zhegnzhou". In the fierce competition, the Africa players once again showed their super strength and won the men’s and women’s full marathon championships.
What should be paid attention to when using astm a573 standard, carbon steel? First, the strength level of carbon steel is low and it is easy to fracture, so carbon steel is not suitable for high strength engineering. Second, the heat-resistant performance of carbon steel is relatively poor, which can not be applied in the long-term high-temperature fields such as boilers. Third, the carbon steel is extremely easy to rust, so it is not suitable for water transport projects. Therefore, the use of carbon steel depends on the use of the environment, if it is harsh conditions, it is better to choose other steel materials.
40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel astm a573 standard is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.
The company's logistics team adheres to the development concept of “gathering advantages, providing superior services, creating value, and leading the market”, and tightly focuses on the strategic positioning of “developing large-scale steel logistics and building large-scale steel supermarkets”. Facing the whole country and integrating into the world to build an "one center, one network" international circulation system. Through the development of 5-10 years, it is expected to form a modern steel industry with annual operating income exceeding 2.5 billion yuan.
