The iron oxide defects on the surface of weathering steel Q295NH

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

NM400 steel is a high-strength wear-resistant steel plate. weathering steel Q295NH, NM400 steel has quite high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; NM400 steel plate can significantly improve the wear resistance of mechanical related parts; therefore, it can increase the service life of machinery and reduce production costs. NM400 wear-resistant steel plate is mainly used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

In the cutting process of wear-resistant plate, weathering steel Q295NH, the steel plate is processed first, because the steel plate is cut after cutting and marking; the commonly used cutting methods for wear-resistant plate are CNC flame cutting and numerical control water cutting, the cost of numerical control flame cutting is not very high, it belongs to primary processing, and its processing range is from 3 mm to 100 mm steel plate. And numerical control water cutting is mainly used under the condition that cutting is required not to deform.

weathering steel Q295NH, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
