The copper brittleness defects control of hardox 500 density

Q690D grade is a low-alloy high-strength structural steel, belonging to the structural steel category. Q690D steel plate executive standard: GB/T16270-2009. Q is the expression of yield strength, 690 is its lower limit yield value, and D is its grade. This grade also has a higher yield strength and tensile strength. Q690 series grades also include Q690C, Q690D, Q690E, Q690F. Delivery status of steel HARDOX 500 density: It should be delivered in quenched and tempered state. In addition, this grade can be delivered according to some special requirements of customers, but it should be indicated in the contract.

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the HARDOX 500 density hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the HARDOX 500 density steel industry.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and HARDOX 500 density steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and HARDOX 500 density medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to HARDOX 500 density, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

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.
