Hot rolled steel coil sheet S890Q equivalent

S890Q equivalent, AR400 wear-resistant plate is a special structural steel plate with high wear resistance, and is an important high-tech wear-resistant steel material. After quenching or quenching and tempering heat treatment, AR400 wear-resistant plate has a dense martensite or martensite-bainite microstructure. The thickness of AR400 wear-resistant plate can reach 100mm. The AR400 wear-resistant plate is widely used in loading machinery, construction machinery, agricultural machinery, mining machinery, metallurgy, electric power and other fields.

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 S890Q equivalent 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 S890Q equivalent steel industry.

Ultrasonic flaw detection emits ultrasonic waves to the S890Q equivalent steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the S890Q equivalent steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

With the increase of temperature, the yield limit of S890Q equivalent will decrease monotonically, but the tensile strength of S890Q equivalent will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S890Q equivalent. Near the blue brittleness temperature, the S890Q equivalent strength increases and the plasticity decreases. The elongation and section shrinkage of S890Q equivalent increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

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.
