Chromium element (Cr element) can improve the strength and hardness of EN S420ML steel plates, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
our company offered 2950 ton A36 steel EN S420ML steel plates plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
In terms of inventory, the recent arrival of new EN S420ML steel plates resources is relatively small. Due to the high ordering cost, the weakening of merchants' purchasing enthusiasm, and the rapid production of steel mills, resulting in the shortage of some EN S420ML steel plates specifications. On the whole, the market has a strong wait-and-see mood. The ex factory prices of steel mills are strong and some resources are in short supply. It is expected that EN S420ML steel plates prices will continue the high consolidation operation tomorrow.
