Effect of heat treatment process on impact properties of 09cuptire-a mechanical properties

A709Gr.36 steel plate is used in construction steel structures, construction machinery and other steel structures, and has been exported to South Korea, Singapore, Malaysia, Dubai, Nigeria and other countries. The 09CUPTIRE-A mechanical properties) cumulative export volume has reached more than 10,000 tons. Construction steel structure, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for construction and engineering machinery parts that require good weldability and toughness.

On October 16, 2019, the Board of Directors of the World Steel Association (worldsteel) elected the following new officers for 2019/2020 at the worldsteel General Assembly in Monterrey. The new 09CUPTIRE-A mechanical properties officers are elected for a one-year period: Chairman - YU Yong, Chairman, HBIS Group Co., Ltd. Vice Chairman - Sajjan JINDAL, Chairman and Managing Director, JSW Steel Limited.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the 09CUPTIRE-A mechanical properties steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This 09CUPTIRE-A mechanical properties method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
