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 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.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

SA572 Gr 42 carbon steel material,The size, shape, weight and allowable deviation of Q390D, Q390D-Z35 steel plate should comply with the provisions of GB/ T709-2016. The maximum thickness of the steel plate is 135mm. When the , Q390D steel, Q390D-Z35 plate thickness is less than 100 mm, the required performance level in the thickness direction is z25; when the thickness is ≥ 100 mm, the required performance level in the thickness direction is Z35, which shall specifically comply with the provisions of GB/T5313-2010,SA572 Gr 42 carbon steel material.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate As a result, they purchase 179 tons as trial order for first cooperation After using the gind plate, the India customer has good comment on our quality Till now, we keep exporting around 100 tons per month as regularly,SA572 Gr 42 carbon steel material.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.SA572 Gr 42 carbon steel material

Boiler steel is different from Boiler steel is used to make boilers Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers Their working temperature is higher than other parts, and the environment is also harsher,SA572 Gr 42 carbon steel material.
