S690QL data sheet main application data

NM450 material is mainly to provide protection in occasions or parts where wear resistance is needed, so that the life of the equipment is longer. Then it can reduce the maintenance and downtime brought by maintenance, and accordingly reduce the investment of funds. S690QL data sheet, NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mine machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

Phosphorus is a very harmful element in S690QL data sheet steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of S690QL data sheet steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

The correct choice of billet type, section shape, size and weight are of great significance to S690QL data sheet steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The S690QL data sheet rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

Our company will accept the product quality objection registration record, pass it to the S690QL data sheet production unit and relevant departments, and timely coordinate the supervision of product S690QL data sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
