Whether NM450 plate material can be quenched to obtain martensite

26SiMnMo (GY5) is armored bulletproof steel, code-named GY4, with good ballistic performance, welding performance and mechanical processing performance. It is suitable for combat command vehicles, explosion-proof vehicles, currency transport vehicles, bulletproof trucks, bulletproof cars, explosion-proof doors, and machines. Need a safe and so on. According to the clients’ requirements, the steel plates with a thickness of more than 10mm can be subjected to ultrasonic inspection one by one, and the acceptance level should be indicated in the contract.

The company adopts the NM450 plate material international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety NM450 plate material management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

In the production process of the ironmaking process, the moisture content and air temperature of the ironmaking blast furnace blast have a direct impact on the fuel consumption and fuel consumption structure of the ironmaking process. Blast furnace blast dehumidification is to remove the moisture in the blast furnace blast, eliminate the adverse effects of atmospheric humidity fluctuations on the blast furnace forward movement, and create stable operating conditions for the fans.

Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, NM450 plate material, and greatly improves the steel material's resistance to atmospheric corrosion.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
