S420ML carbon steel plate sheet carbon steel high properties

Cleveland cliffs announced on March 13 that it had completed the acquisition of AK S420ML carbon steel plate sheet steel, foreign media reported In the transaction of holding), shareholders of Cleveland cliffs and AK steel respectively voted on the US billion acquisition agreement at their respective shareholders' meeting to complete the resolutions required for the announcement of acquisition of AK steel S420ML carbon steel plate sheet at the beginning of the year. The acquisition is Cleveland cliffs' first foray into steel manufacturing.

The hardness and impact toughness of precipitation-strengthened wear plates, S420ML carbon steel plate sheet 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.
