JIS SS400 plates equivalent material

JIS SS400 plates, Q890D steel plate is quenched and tempered steel for high-strength structure, the implementation standard: GB/T 16270. In the Q890D steel grade, "Q" means yield, "890" means yield value, and "D" means grade level. The equivalent material of Q890D is EN S890Q steel. The size, shape, weight and allowable deviation of Q890D steel plate shall meet the requirements of GB/T709. Q890D steel plate delivery status (heat treatment): quenching and tempering.

Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, JIS SS400 plates, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.

Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers". I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! And sincerely hope to establish a long-term cooperative relationship with them, mutual benefit and common development.

In order to improve the JIS SS400 plates corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating.
