4mm thick SA588 grade A weathering steel plate

SA588 grade A weathering steel plate, NM400 wear plates are used for wear-exposed structures, such as protective pads and shell walls of prospecting machines and bulldozers. Support or reinforcement board; cutting board for truck rollover; mixing elements and conveying elements, chute grooves, display screens, machine tools, crushers and shredders, waste briquetting presses, blades, paving abrasives and agricultural machinery.

The hardness and impact toughness of precipitation-strengthened wear plates, SA588 grade A weathering steel plate are also improved. For example, the hardness of the wear-resistant plate after precipitation strengthening is 230-300 HBW, and the impact toughness is 140-180. More importantly, the improvement of the above indicators does not bring about a significant decrease in plasticity. The performance of the wear-resistant plate after water quenching at 1100℃, first holding at different temperatures in the middle temperature zone, and then water quenching at 970℃. With the increase of the holding temperature in the middle temperature zone and the extension of the holding time, the number of carbides in the steel increases, and the precipitation strengthening effect increases, resulting in an increase in hardness.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled SA588 grade A weathering steel plate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the SA588 grade A weathering steel plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
